Upgraded Silicone Cap Starter Kit

The kit includes 21 different sizes ranging from 0.070" to 0.750" diameter. Each size comes with 2 caps so you can test fit on your parts before committing to a bulk order. This covers most common threaded stud and pin masking needs in powder coating and painting operations.

These silicone caps are rated to 600F (315C), which covers standard powder coating cure temperatures of 350F to 450F with a comfortable safety margin. They maintain their shape and seal through repeated heat cycles without hardening, cracking, or leaving residue on the masked surface.

Silicone caps work with powder coating, e-coating, wet painting, anodizing, and plating. The silicone material resists chemicals used in pretreatment and coating processes. Caps create a tight seal that prevents coating from reaching threaded holes, studs, and pins during the finishing process.

Yes. Silicone caps are designed for repeated use across many coating cycles. After each run, pull the cap off and any cured coating peels away from the silicone surface. A single cap typically lasts 20 to 50 uses depending on cure temperature, chemical exposure, and how carefully they are removed.

The Upgraded Silicone Cap Starter Kit is priced at $85.00 and ships in stock from Creative Coating Solutions. The kit includes 42 total caps across 21 sizes. This is a cost-effective way to identify the exact sizes you need before ordering larger quantities of individual cap sizes.
