Catalyzing amino-substituted organosilane ester primers

Abstract

Methods for bonding a polymer surface (e.g., a fluoropolymer surface) to a substrate, including foam tape substrates, and articles produced thereby. The methods can include using a primer composition having an amidine catalyst in combination with an amino-substituted organosilane ester.

Background technique [0003] Fluorine-containing polymers (also known as "fluoropolymers") are a class of commercially available materials. Fluoropolymers include, for example, crosslinked fluoroelastomers and semicrystalline or glassy fluoropolymers. Fluoropolymers are generally highly thermally stable and are particularly useful at high temperatures. They also exhibit extreme toughness and flexibility at very low temperatures. Many of these fluoropolymers are almost completely insoluble in various solvents and are often chemically resistant. Some have extremely low dielectric loss and high dielectric strength, and can have unique non-stick and low-friction properties. Fluoropolymers, partic...

Problems solved by technology

However, when one of the layers is a fluoropolymer, it is often difficult to establish a high bond strength due in part to the non-adhesive qualities of the fluoropolymer
