Indoor intumescent fire retardant coating for steel structure (water-based)

PRODUCT INTRODUCTION

The fire relardant coating is a water-based intumescent fire relardant 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 coating 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 condensalion, frost and water droplels on rainy days. The construction process should avoid rain andexposure.The curing time should be prolonged for yellow mold days.

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

4. The coating construction should be spraying. The coaing thickness should be controlled at about 1.5mm for thin type and 0.2mm forultra-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.

Seriai number	Fire resistance time	Construction thickness	Construction times	Theoretical dosage	lllustrate
1	150min	4.5mm	Ultra thin 10 / thin 4	5kg	The thinner the first pass, the better, try tocontrol it to about 0.5mm, about 4 hoursafter the surface is dry, you can apply thesecond pass, after each pass, control it toabout 0.8mm, until the specified thickness.
