UV Inhibitors and Surfactants

Hapco’s UV Screen 101™ is used when a part will see outdoor use on a continuous or periodic basis. Direct sunlight can be detrimental to a part’s clarity and UV Screen 101™ can enhance a material’s ultraviolet resistance. Anti-Air™ is often used when a material is too thick to degas in a vacuum chamber.

Color Dispersions

Opaque and Translucent Colorants

Hapco’s Color Dispersions have been used extensively in the prototyping and aftermarket parts industries to give pieces a unique look as opposed to painting them. Whether it’s intended to hide proprietary circuitry, or highlight individual components, Hapco’s Color Dispersions will leave a lasting impression.
