Detailed introduction

WBLY-02 outdoor thin fireproof coating

WB (LY-B) outdoor thin steel structure fireproof coating, its fire resistance, physical and chemical properties are better than the requirements of GB14907-2002 standard WB type. The product can be widely used in fire protection of large-span outdoor steel structures in industrial and civil buildings. Has the following characteristics:

  • People-oriented, green and environmentally friendly, the first fire-resistant coating product in China that has passed China Environmental Labeling Product Certification.

  • The production time is early, the technology is mature, the technology is advanced, and the formula is reasonable.

  • Has good durability and reliable fatigue resistance. After 1.2 million times of stress fatigue test (equivalent to 30 years) and resistance to atmospheric aging (equivalent to 30 years of test), the coating did not appear chalking, cracking, slagging, shedding, etc. The coating was bonded to steel Good, the test results are the first in China. This product was listed as a national key new product in 1995.

Construction method 1. Spraying should be used for construction. Self-weight spray gun is used for spraying tools. The air pump pressure should be 0.4-0.6Mpa during spraying.
2. Pay attention to the consistency of the spray coating. It is advisable not to fall down when spraying.
3. According to the requirements of the fire resistance limit level, spraying is performed in 2-3 times, and the second time after the curing.
4. If surface coating is needed, wait until the bottom layer is dry.
3. Storage and transportation < br This coating is suitable for storage under the environment above 0 ℃. Shelf life is 6 months. Packaging and transportation should be freeze-proof and impact-resistant.
