Applications: Gd-app101 is an effective fire retardant for applications such as: 1, intumescent latex and solvent based paints. 2, intumescent mastic, caulks and putties. 3, polymer systems such as polyethylene, polypropylene, polyurethane, 4, rubbers, acrylics, polyterephthalate. 5, building materials such as wall coverings, ceiling tiles, roofing products, wall panels, wood chip board.
