Abstract
A method for adhering/bonding a frame profile (e.g., weather strip, water seal, spacer, etc.) to a substrate (e.g., glass or plastic substrate) in the context of a vehicle window unit. A frame profile is formed via extrusion so as to include both a polymer profile portion and a selectively activatable interface or adhesive portion. Following extrusion, the frame profile may be stored, cut, trimmed, cure, etc. At some point following extrusion, the interface/adhesive is in a non-activated state, or at least in a state where it is not activated to an extent sufficient to bond/adhere the frame to the substrate. To adhere/bond the frame profile to the substrate, the interface/adhesive portion of the frame profile is activated (e.g., heat activated). Following and/or during heat activation, the frame profile is pressed against the substrate, or vice versa, so that the activated adhesive bonds the polymer profile to the substrate.
