A pressure sensitive adhesive composition can cure via hydrosilylation to form a pressure sensitive adhesive. The pressure sensitive adhesive composition may be coated on a substrate and cured to form a protective film. The protective film is useful in flexible OLED device fabrication processes, e.g., for protection of passivation layers.

Waterproof urethane-based adhesive compositions for flooring applications. Silane is reacted with a prepolymer to at least partially end-cap the prepolymer. A reinforcing extender, a thixotropic agent, a magnetic agent, a first catalyst, and methylethylketoximino (MEKO) silane are also added to the composition to form the deactivated adhesive mixture. Prior to coating a substrate with the adhesive, a second catalyst is added to the adhesive mixture. The second catalyst speeds up the curing time and improves the shelf life of the moisture cure adhesive. The adhesive is cured to a final product that is waterproof, hydrolytically stable, and pH resistant.
