Under normal conditions of use (and in the case of a coating on its appearance), it is estimated that the service life is not less than ten years, in the temperature range of -10 ℃ ~ 80 ℃ curing foam to maintain good flexibility and bonding force. After curing the foam has a filling, bonding, sealing and other functions. Another flame retardant polyurethane foam can achieve B and C-class flame retardant.
