WATERPROOF ADHESIVE COMPOSITIONS
20230212445 · 2023-07-06 ·

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.
