Fire-retardant mastic |
The fire-retardant mastic is made of asphalt, macromolecule resin, mineral filling, added with proper amount of fire retardant. It has the properties of air-tightness, waterproofing, refrigerating prevention corrosion-resistance,rigid cracking and aging, availability for cold construction under normal temperature, and fire-retardant property after drying. It is an external protection layer used together with cellular glass or PU rigid cellular glass, and also a perfect fire-proof, water-proof, and damp-proof cold insulator |
Usage:Apply the mastic on the surface of heat insulation layer, in 3mm thickness, and line one layer of water-proof glass fabric or plastic window curtain in the middle;
Apply evenly, level smoothly, prevent from air bubble;
Use 12.5kg (including the loss) in every 6mm2. |
