Cockling-Protecting PSA Release Liners from Heat and Humidity (.pdf)
Siliconised release liners play a critical role in pressure-sensitive adhesive (PSA) systems, protecting the adhesive during transport and storage and through various converting and assembly processes. To successfully provide this protective function in varying atmospheres, the release liner must

What Are Refractory Metals?
tungsten can be used at high temperatures, oxide films become volatile above temperatures of. approximately 538oC (1000oF). So, for use at extremely high temperatures, tungsten parts must be coated, used in. a vacuum; or be surrounded by a protective atmosphere. Typical uses involving protective

Finishes and Coatings
coatings: Zinc, cadmium, tin, nickel, and chromium coatings are most common for fasteners. Zinc is preferred for industrial atmospheres. Cadmium is best in marine atmospheres but is more expensive than zinc. Corrosion products form a protective film on zinc and cadmium surfaces, but the film on cadmium
