Core Performance Features

The product is used for fireproof protection of other decorative materials of buildings. The coating not only has a certain decorative effect, but also expands rapidly when encountering high-temperature flame to form a uniform and dense carbonized layer which is tens of times that of the coating, and the carbonized layer has low thermal conductivity, good structural strength and high temperature flame shear impact resistance, can effectively prevent the combustion flame retardant effect of the material protected in the fire scene, prevent the extension of the expanded fire source, and win time for rescue and fire extinguishing. It can minimize the loss caused by accidental fire.
The product consists of ammonium polyphosphate with high polymerization degree, melamine, pentaerythritol and other synthetic expansion carbonization flame-retardant materials, titanium oxide, antimony oxide and other pigment fillers, water dispersible emulsion and other coating additives, and does not contain asbestos, heavy metals, benzene and other petrochemical solvents and other harmful components.

Construction Process

1. Before construction, the surface of components shall be inspected and accepted, and the surface shall be clean, dust-free and oil-free;
2. Open the packaging barrel. If there is sediment or viscosity (can not be hardened and dried), add a proper amount of water, use an electric stirrer to stir up and down evenly without affecting the quality, and then carry out spraying, brushing or roller coating construction. Apply 1 ~ 2 times according to the construction situation. The surface of the coating constructed in the previous time shall be dry (about 12h at room temperature) until it reaches the thickness required by the design;
3. Precautions: It is not suitable for construction under low temperature conditions; it is not suitable for open construction under wind, rain, sand and dust weather conditions; During construction, if the viscosity of the coating is too high, a proper amount of water can be added and stirred evenly;
4. The construction curing period is 15 days, and the outer layer shall be painted with protective finish before the water resistance and moisture and heat resistance test.
