Product Description: SP-1045 is a heat reactive, phenolic resin used in the resin curing of butyl rubbers*, adhesive systems and sealants. A halogen donating activator (typically 5 phr of mercaptan-modified polychloroprene is used in butyl polymers) should be added for best results. Halogenated butyls do not require a halogen donor as activator.Information provided by Akrochem Corporation |
