PRODUCT INTRODUCTION

The fire retardant coating is a water-based intumescent fire retardant coating, which has the characteristics of thin layer and highadhesion. The paint can play the role of fire prevention and anti-corrosion when brushed on the surface of the steel structure, and thesurface of the coaling rapidly expands when exposed to fire to form a uniform and dense fire protection and heat insulation layer, so asto achieve the fire protection effect of the steel structure.

Executive standard:GB14907-2018

CONSTRUCTION METHOD

1. Thoroughly remove dust and rust from the surface of the steel structure before construction.

2. The construction should be at a temperature (5-35)'c, and the relative humidity should be controlled within 80%. The steel structureshould not be operated due to condensation, frost and water droplets on ralny days. The construction process should avoid rain aneexposure.The curing time should be prolonged for yellow mold days.

3. After the coating is opened, it should be stired evenly with an electric tool, and then the construction should be carried out aftesuficient stirring. The coating should be able to level and not sag.fthe paint is found to be too thick during construction,it can be dilutecby adding an appropriate amount of water and mixing well before construction.

4. The coaling construcion should be spraying. The coating thickness should be controled at about 1.5mm for thin type and 0.2mm foultra-thin type, subject to no sagging. The next coating can be applied after the surface of the coating is dry.

5. Before the coating is completely dry, it is forbidden to wash with water and rain.

6.Outdoor fireproof coating shall be provided with waterproof protective layer according to normal construction.

Seriai number	Fire resistance time	Construction thickness	Construction times	Theoretical dosage	lllustrate
