Choose The Right Mold Release
When using a mold release agent from Stoner Molding, there are three primary types.
- A silicone or sacrificial wax coating will transfer the mold release agent onto the product after unmolding, meaning you may need to clean the product before a secondary application.
- A semi-permanent mold releasecross-links and cures to the mold for multiple releases per application, significantly reducing the need to clean a part before proceeding to the next step in the manufacturing process.
- Finally, if the part needs post-production applications, like gluing, painting, and welding, youll need to use a mold release designed for that secondary decorating step.
To eliminate the need for cleaning molded products after production, choose a semi-permanent mold release or use one designed for the next post-production activity, like a paintable release.
If you use sacrificial mold release agents and want to clean those parts after the molding process, we have various solvent- and water-based cleaners to consider. Be aware that if there is a lot of mold release on your finished product, you likely applied too much of it.
Choose The Right Mold Solutions Products
When you choose the right mold solutions for your molding process, youll find you can reduce the time needed to clean molded parts before heading to secondary applications. The industry-leading products Stoner Molding Solutions provides are specifically designed to minimize prep work before beginning post-molding operations. Use Stoner Dry Film Mold Release, a sacrificial mold release containing no silicone, oils, or waxes. This mold release is great for molding silicone rubber, and most molded parts dont require cleaning before heading to secondary applications in the molding process.
Another product is the Stoner Mold Release & Ejector Pin Lube, which is a paintable release agent. You can use it for plastics or rubber molds. This mold release agent allows the parts to be painted, plated, hot stamped, or decorated after molding. Remember, choosing the right mold release product will help minimize the amount of cleaning needed before heading to post-molding applications.

An Adjustment Period For Tires And Drivers
Even if youve refitted your car with the same brand and model of tires you previously had, you might notice a difference in how driving feels. Its likely your old tires had very little tread depth by the time you replaced them. Tires with very little tread tend to respond quicker, because theres less tread that needs to flex during maneuvering. So, new ones might feel slightly less responsive before theyre fully broken in.
As well as enabling your tires to adjust and start performing at their best, a gentle breaking in period will give you a chance to adjust to your new tires, too.

Removing Mold Release From Rubber Parts
Like plastic parts, we recommend using a mold release that doesnt require cleaning before rubber parts head to a secondary application, like metal bonding. A water-based mold release, like Stoner Molding Solutions TraSys® water-based release products, is a semi-permanent mold release. Therefore, you shouldnt require additional cleaning before the molded products head to a secondary application.
However, if you find a remaining mold release residue on your molded products, it may need extra curing time or more heat for the mold release to evaporate entirely. Read this Knowledge Base article for more information on making the switch to water-based mold release from a solvent-based release.
If you use a sacrificial mold release for your molding process, clean any extra residue left on the molded part with Stoners A320 All Purpose Mold Cleaner. It quickly cuts through the mold release, grease, oil, and other residues to leave your molded part clean.
Why Do My Brand New Tires Look Dirty
If youve just purchased new tires, you may be wondering why they look dirty. In most cases, this is simply due to the fact that they are brand new and have never been used before. Once you start driving on them, the dirt and grime will quickly wear away, revealing the clean surface beneath.There are a few exceptions to this rule, however. If your tires were shipped to you or if they were stored in a warehouse for an extended period of time, they may have picked up some dust and debris during transit. In these cases, its best to give them a quick once-over with a damp cloth before hitting the road.Finally, keep in mind that even brand new tires arent immune to the elements. If its been raining or snowing recently, your tires may pick up some mud or grit that will need to be cleaned off before long.

How Do You Get Rid Of Dots On New Tires
There are a few different ways that you can get rid of the dots on new tires. One way is to use a tire shine product. This will help to mask the dots and make them less visible. Another way is to use a tire cleaner. This will remove the dots completely. Finally, you can also sand the tires down. This will remove the top layer of the tire and make the dots less visible.
Why Antiozonant Causes Tire Sidewalls To Turn Brown
Tires bloom because antiozonant pushes its way to the outer edge of the rubber casing with time. As the element comes into contact with oxygen, it leaves a brown residue on the surface of the tire. Antiozonant is organic and helps tires last longer as it slows deterioration due to oxidation. This is what makes it possible to manufacture long-lasting high-mileage tires that can last up to 10 years.
The rubber structure is built in a way that allows the element to move forward to the surface, thus continuingly providing the material with its benefits. As a result, the tire remains pliable and UV/oxygen-resistant for a longer time.

Note: When new tires are fitted, they should not be subjected to sudden acceleration, hard cornering, maximum power or braking for at least 100 miles. Failure to do so may result in loss of control and serious injury. The 100 mile run-in is required to adjust to the feel of new tires versus the worn tires.

Background Of The Invention
1. Field of the Invention
The present invention relates to a method for removing a mold release agent. In particular, the invention relates to a method for removing a mold release agent adhering to a tire surface so as to affix an adherend to the tire surface after a cure-molding process.
2. Description of the Related Art
Conventionally, the tire manufacturing process includes post-processes of affixing adherends to the inner and outer peripheral surfaces of a tire after cure-molding, in which designs, emblems, etc., are printed on the tire surface , a sealant for prevention of flat tire or an acoustic absorbent to reduce noise of vehicular travel is applied, or a tire monitoring device for monitoring the tire inner pressure is attached to the inner surface of the tire. A process of removing mold release agent adhering to the tire surface after molding is carried out as a step prior to those post-processes. The mold release agent is applied to the surfaces of molds and bladder in the cure-molding process to make the stripping of the tire from the molds easier, but is found adhering to the tire surface at the stripping of the tire from the molds. In the release agent removal process, the mold release agent adhering to the tire surface is wiped off with a wash solution or removed together with the rubber by buffing.

Silicone As A Contributor To Tire Blooming
Tires do not bloom because of silicone-based tire dressings. Silicone is sticky, so it may allow dirt and dust to hold on to the surface of the tire as you drive, which makes tire sidewalls turn brown. The tire becomes dirty but doesnt bloom.
In this case, you can remove the color with a simple clean, using a brush and some water. Likewise, you can also remove silicone-based dressings with special degreasers and scrubbing.

How To Clean Brown Tires
So, now youre ready to give your ride a makeover and get those tires looking their best! By the end of these instructions, you should hopefully have taken care of the problem without having to buy new tires.
This is what youll need:
What Causes Tire Blooming
Okay, before we can deal with the problem, we first need to understand what causes it.
Lets dispel the central myth: that the cause of tire blooming is tire dressings/products. People have suggested that these products will degrade over time and leave the brown marks behind.
While this makes sense, it isnt true!
The cause of tire blooming is the tire itself. Tires might seem like theyre just lumps of rubber, but they are highly specialized pieces of equipment. Manufacturers add multiple compounds and chemicals during the production process, and one of those compounds is called antiozonant.
Antiozonant helps to prevent the tire from degrading over time. Rubber will naturally dry out and crack unless its protected. Antiozonant doesnt completely prevent this, but it does slow the process down.
Unfortunately, it also reacts with the outside elements. Air and water are the main culprits here, and they work to break down the antiozonant over time. Its this breakdown that leads to that ugly brown color.
A quality tire dressing helps to stop this process by forming a barrier between the tire/antiozonant and the outside elements. With this barrier in place, the degradation process occurs more slowly, and may even prevent it completely with regular applications. So, a tire dressing has two benefits: not only does it give that rubber a fresh black color, but it also helps to prevent blooming and decay in the future.

Do All New Tires Have Hairs
Although vent spews are found in new tires only, not all tires have them, according to some drivers.
However, this is not a cause of concern because it doesnt affect how the tire performs or other essential features of the tire.
The hairs will only be present in new tires therefore, some may have them in plenty depending on the brand or manufacture process, while others have a few.
Once you buy your new set of tires, you should prioritize other features such as tread, which is more critical for the performance of your tires.

Should I Wipe My New Tires
Yes, you should definitely wipe your new tires before driving them. Heres why:1. Wiping your tires helps remove any manufacturing oils or chemicals that may be on the surface of the tire. These can be harmful to the tire and can potentially cause premature wear.2. Wiping your tires also helps to clean off any debris or dirt that may have accumulated on the surface during shipping and handling. This can help prevent the tires from being damaged while youre driving.3. Finally, wiping your new tires gives you a chance to inspect them for any damage or defects. This is important because it allows you to catch any problems early on and get them fixed before they cause more serious damage down the road.

Use A Paintable Mold Release For Plastic Parts
Stoner Molding recommends using a paintable mold release for the plastics industry, like Stoner E302 Rocket Release. This product is the most paintable release available, allowing the molded parts to proceed to secondary painting, stamping, bonding, or other applications without the need to clean the piece.
If your molded part doesnt require a secondary application, use a silicone-based mold solution. If there is a residue that needs cleaned on the molded part, use mild dish soap and a hot water bath. Immerse the molded parts into this bath, which will cause the silicone to rise to the top of the surface. Skim away the silicone and give the pieces a final hot water rinse. Let them air dry or use compressed air for drying. You can also use isopropyl alcohol to remove silicone-based mold release.
Mold Releases As Contributors To Tire Blooming
Mold releases used in tire manufacture dont make tire sidewalls turn brown. However, they contribute to the issue as they keep antioznant on the surface of the tire. Moreover, the more of it is left near the outer edge of the tire structure, the more the oxidation process will make it leave brown residue.
Mold releases are non-stick lubricants put in tire molds. They help release ready tires from the forms freely. Some of the lubricant usually remains on the tire, so it may contribute to blooming after just a couple of weeks of driving.
