Junbond Concrete Stone & Brick PU Foam Adhesive

It is a one-component, economical type and good performance Polyurethane foam. It is fitted with a plastic adapter head for use with a foam application gun or a straw. The 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. It is environmental friendly as it does not contains any CFC material.
