U-428 Plus adhesive is a one-component, conventional-cure adhesive. It eliminates steps and speeds installations by incorporating glass primer into the urethane. It is primerless to glass and require only BETAPRIME 5404A primer if the metal is scratched during glass removal, or when bonding to encapsulations or pre-applied adhesive systems (PAAS). U-428 Plus provides improved decking, even in hot weather. 
Conventional-cure adhesive like U-428 Plus rely on temperature, humidity and time to cure. The water in the air causes a chemical reaction in the adhesive. The adhesive bead cures from the outside to the center as the moisture diffuses into the adhesive. The curing bonds the adhesive to the substrates and existing bead of urethane adhesive.

Structurally bonded or direct glazed automotive glass, such as windshields, backlites, quarter glass and other stationary glass
