KALENE® 800 is a low-molecular-weight liquid polymer derived by the depolymerization of butyl rubber. It vulcanizes at either ambient or elevated temperatures with the standard curatives for butyl rubber. KALENE® 800 is light gray and contains no solvents or additives. KALENE® 800 has the lower viscosity of the two KALENE® grades available and is the preferred liquid butyl rubber for coating applications. KALENE® 800 provides gas impermeability, chemical resistance, moisture resistance, good electrical properties, and excellent vibration/sound damping qualities.

ISOLENE® 400-S is a low-molecular-weight liquid polymer derived from synthetic polyisoprene rubber. It offers the performance and processing characteristics of natural rubber with the added benefit of a lighter color and none of the natural impurities inherent in natural rubber products. ISOLENE® 400-S is a high-viscosity liquid at room temperature. It is a translucent, honey-colored liquid in bulk form and virtually clear in a thin film.

KALENE® 1300 is a low-molecular-weight liquid polymer derived by the depolymerization of butyl rubber. It vulcanizes at either ambient or elevated temperatures 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 and sound damping qualities.

ISOLENE® 40-S is a low-molecular-weight liquid polymer derived from synthetic polyisoprene rubber. It offers the performance of natural rubber with the added benefit of a lighter color and none of the natural impurities inherent in natural rubber products. ISOLENE® 40-S is a lower viscosity liquid than the other ISOLENE® liquid rubber products. It is a translucent, honey-colored liquid in bulk form and virtually clear in a thin film.
