KALENE® 1300 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. KALENE® 1300 is light gray and contains no solvents or additives. KALENE® 1300 has the higher viscosity of the two KALENE® grades available and is the ideal choice for applications requiring the maximum retention of physical properties at the expense of a maximum reduction in viscosity. KALENE® 1300 is the preferred liquid butyl rubber for adhesive applications and a reactive additive to ordinary butyl rubber. KALENE® 1300 provides gas impermeability, chemical resistance, moisture resistance, good electrical properties, and excellent vibration/sound damping qualities. Features and Benefits: KALENE® 1300 offers the performance benefits of butyl rubber and the processing convenience of a liquid. It makes convenient bases for sealants, coatings, and adhesives. These coatings have higher solids than those based on butyl rubber because the KALENE® products are liquids. KALENE® elastomer's butyl properties impart chemical resistance to a wide variety of sealants and adhesives. It is ideal for applications requiring chemical and moisture resistance. KALENE® products also provide tack to pressure sensitive adhesives and improve the adhesion of butyl-based adhesives and sealants. Since they cure by the same mechanism as butyl rubber, they become part of the polymer matrix. Information provided by H.B. Fuller Company |
