KALENE® 1300 by H.B. Fuller is a low molecular weight liquid polymer derived by the depolymerization of butyl rubber. It vulcanizes at either ambient or elevated temperature with the standard curatives for butyl rubber. It contains no solvents or additives. It provides gas impermeability, chemical resistance, moisture resistance, good electrical properties, and excellent vibration/sound damping qualities. This grade also displays tack to pressure sensitive adhesives and improve the adhesion of butyl-based adhesives and sealants. KALENE® 1300 is used in construction sealants and pressure sensitive adhesives. The shelf life of this grade is 2 years.
