Specifically designed for powder coating and E-coating masking applications, StockCap's silicone caps will resist temperatures up to 600°F (316°C) and have a service life beyond a single use. 

High Temperature

Silicone's ability to function under extreme heat for extended periods of time has made it the masking product of choice for high temperature painting and powder coating. 

Coating Line

Unlike silicone "lubricants" that can wreak havoc in a coating facility, silicone caps are solid material and pose no contamination risk to a coating line. 

Medical Packaging

Used extensively in the medical packaging field as silicone is a very pure material that can easily withstand the sterilization temperatures used in this market.
