Abstract:
The present invention provides an adhesive material with improved bonding performance to a wet substrate, the adhesive material includes a first component selected from a polysiloxane-based adhesive, or a polyurethane-based adhesive; and a second component of a catechol-containing polymeric additive which includes a reaction product of polyvinylpyrrolidone with 3′,4′-dihydroxy-2-chloroacetophenone, and the weight ratio of polyvinylpyrrolidone to 3′,4′-dihydroxy-2-chloroacetophenone ranging from 10:1 to 1:1. The adhesive material being a mixture of at least the first component and the second component, where the second component is approximately 1 wt. % to 10 wt. % of the first component.
