BLOC GPIB2400 Grafted Polyisobutylene Adhesive Resin

BLOC GPIB2400 is an acrylic-grafted polyisobutylene resin for water-blocking and sealing adhesive applications. It is used in reactive membrane manufacturing where excellent moisture barrier performance, strong tack, and compatibility with multiple resin systems are required.

The resin also provides strong adhesion to glass, metal, plastic, and membrane-based substrates.
