Product advantages 

Excellent fire resistance: can withstand high temperatures above 800°C, with a fire resistance limit of 1-4 hours, reducing the risk of structural deformation. 
Environmentally friendly and safe: made of inorganic materials, no toxic gas release, in line with fire protection and environmental protection standards (GB 8624-2012). 
Strong bonding: firmly bonded to concrete, brick walls, steel structures and other bases, not easy to hollow out and fall off. 
Good durability: anti-freeze, anti-seepage, corrosion resistance, long-term use performance is stable. 
Convenient construction: can be mechanically sprayed or manually plastered, similar to the construction process of ordinary mortar.

Product Description

Letong fireproof thermal insulation mortar is a premixed powder mortar composed of inorganic compounds and perlite. After mixing with water, these compounds will form a highly insulating fireproof sealing material to prevent fire and smoke from spreading through openings in fire-resistant walls and floors. It has a granular surface and a low density. The coating does not expand when heated. Because it has good thermal insulation, it is also called thermal insulation fireproof coating. Its fireproof mechanism is to use the inherent good thermal insulation of the coating to prevent the heat of the fire from transferring to the surface of steel and other buildings, and form a dense glaze at high temperature, which can effectively isolate oxygen and reflect heat, delay the temperature rise of the steel structure, and play a role in fire protection.
