Question: We have been considering organosilane adhesion promoters for use in several of our adhesives, and I am trying to understand how the organosilanes act chemically. Most literature shows them working primarily in adhesives for bonding glass. Will they work for other substrates (e.g., metals)?
Formulating pressure-sensitive adhesives (PSAs) presents a number of complex challenges. The adhesive must flow and set without activation from anything more than the pressure of a hand, remain permanently tacky, and exhibit a strong bond—often to a variety of substrates, such as wood, glass, or metal—for as long as the application requires or until the end user decides to remove it.
I work in the technical department developing coatings based on various polymer backbones. I am familiar with typical polyurethane raw materials, but have recently become aware of polyaspartic coatings. Could you provide an overview of this technology?
