China Waterproof Spray PU Foam for Packaging Purpose

High density 750ml polyurethane spray foam for construction
DEscriptION
Multi purpose large expansion PU foam sealant is an one-component, self-expanding, multi-purpose polyurethane foam.This foam will expand and cure by moisture in the air.It is used for a wide range of building applications.It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation.Higher expansion rate than normal Pu foam.
ADVANTAGE
1.Can apply around 70 meters ( 30mm*15mm)
2.Most cost effective for each window or door.
3.No shrinkage and cracking after cured.
4.Better adhesion and harder.
APPLICATIONS
