Key properties:
1, low water solubility gd-app101 has low water solubility which makes it useful in application where the product is exposed to high humidity conditions or water.
2, high phosphorus content -gd-app101 contains 72.5% phosphorus (as p2o5) which makes it a very effective fire retardant.
3, nearly neutral ph-gd-app101 can be neutralized or brought to the alkaline side by the addition of small amounts od ammonium hydroxide.
4, non-halogen-gd-app101 is a highly effective non-halogen fire retardant.
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.
