Uses and Characteristics:

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

Polyether for waterproofing materials can also be used as a crosslinking agent for polyurethane elastomers, rigid foam crosslinking agent, and foam sealant. Used in polyurethane waterproofing materials to increase product hardness. Used as a crosslinking agent for polyurethane elastomers to increase product hardness; used as a crosslinking agent for rigid foam to reduce the viscosity of the compound; used in foam sealants to increase foam hardness and curing speed. Both can be used in foam sealants, with MN-500 providing a more significant effect in increasing foam hardness, while MN-700's performance falls between the two.
