ABSTRACT:
A primer for block copolymer based sealants comprises a solution of the block copolymer, an adhesion promoting resin compatible in the higher softening point block of the block copolymer, a silane and oxidation/UV stabilizers. A process for applying a block copolymer based sealant comprises coating a substrate with a thin layer of a solution of block copolymer, an adhesion promoting resin associating with the block having the highest softening point, a silane and oxidation/UV stabilizers in a solvent, evaporating the solvent and applying a layer of block copolymer sealant over the residue left after evaporating the solvent.
