Product overview
This product is a polyurethane two-component reactive sealant: it is composed of resin (A component) and curing agent (B component), and after fully mixing the sealant (tan curing agent and resin) when used, it is injected into the shell cavity from the glue injection port and completely cured.
This product doesn’t contain solvents. It has the characteristics of minimal shrinkage, good permeation resistance, high volume resistivity, good insulation after cured. The product is constructed under room temperature and operated conveniently. It effectively combines waterproof property and insulation, and becomes a special material for sealing, fireproof and flame retardant of underground high-voltage cable joints.
