Effect of Silane Coupling Agents on Adhesion of Polybutadiene to Glass
1993
The chosen silane coupling agents consist of a polybutadiene skeleton with Si(CH3)2OCH3 or Si(OCH3)3 pendent groups hydrolyzable on the glass surface. Their number, and therefore the amount of potential bonds, can be varied. These modified polybutadiene polymers act as primer compatible with the polybutadiene coating to be deposited.
The subsequent cross-linking of the double bonds of the silane primed surface with polybutadiene is initiated by benzoyl peroxide, creating chemical bonds between the solid support and its coating.
The strength of the adhesion of polybutadiene to glass is measured by the 180° peel test and the values are compared with a non-modified glass surface.
