Uses and Characteristics:

(1) Polyether for crosslinking agent, used as a crosslinking agent in polyurethane elastomers to increase product hardness; as a crosslinking agent in rigid foams to reduce the viscosity of the compound; in foam sealants to enhance foam hardness and curing speed.

Polyether for waterproofing materials can also be used as a crosslinking agent for polyurethane elastomers, rigid foams, and foam sealants. When used in polyurethane waterproofing materials, it increases product hardness. As a crosslinking agent for polyurethane elastomers, it enhances product hardness; in rigid foams, it reduces the viscosity of the compound; in foam sealants, it improves foam hardness and curing speed. Both can be used in foam sealants, with MN-500 providing a more noticeable increase in foam hardness, while MN-700 offers performance between the two.
