IsoMelt HMPUR 1119

IsoMelt HMPUR 1119 is a one-component reactive hot melt adhesive that combines quick initial bond strength that continues to develop strength after application in the presence of atmospheric moisture. IsoMelt HMPUR 1119 cures into a cross-linked inert structure providing exceptionally high adhesion to wood and other porous substrates while also maintaining superior resistance to extreme temperatures and chemicals. IsoMelt HMPUR 1119 has an excellent initial bond, dramatically reducing downtime for a more efficient and productive manufacturing process. Ideal results are obtained when one of the surfaces adhered is permeable to humidity. Impermeable surfaces may need abrading to increase mechanical bond. Once set, the material can only be removed by mechanical means and it should not be removed by burning. IsoMelt HMPUR 1119 is idea for profile wrap applications.
