Indoor non-intumescent fire retardant coating for steel structure

PRODUCT INTRODUCTION

The fire retardant coating is a two-component heat insulating fire retardant coaing.When the coaling encounters a fire,a glaze layer isformed on the fire site for heat insulation and fire prevention, so as to 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.

Nole: At the construction site, there should not be too many ingredients at a time. Generally, use as much as you want to prevent failure
It is best to use it up in 30 minutes before using it again.

Seriai number	Fire resistance time	Construction thickness	Construction times	lllustrate
1	180min	32mm	5 all over	The primer shall be roughened first and sprayed with styrene acrylic lotion or 707 glue with a thickness not exceeding 1mm,Each construction is subject to non-sagging, and the next pass can be carried out after the coating surface is dry, and each pass is controlled at about 6mm until the thickness required by the design is reached.
