Multi-component Polyurethane Waterproof Coating

1. Description

The two-component polyurethane waterproof coating is a film formed by reaction and solidification of two components A and B. Component A is a transparent to light yellow viscous liquid containing isocyanate end group generated by polymerization of polyether, polyisocyanate and other raw materials; Component B is a paste formed by mixing and processing of cross-linking agent, accelerator, toughener, tackifier, mould inhibitor, filler and pigment. When in use, A and B components are mixed in a certain proportion, stirred evenly, scraped and coated on the base surface, and after several hours of reaction curing, a waterproof coating with elasticity, toughness and durability is formed.

2. Product usage introduction

Multi-component Polyurethane Waterproof Coating is used for spraying method and scraping method.

• First of all,base cleaning then ingredients and construction of additional layer .
• Final,large area painting and protective layer construction.

3. Characteristics

• It does not contain toxic and harmful substances such as coal tar.
• It is solidified at normal temperature, the waterproof layer is seamless, flat and smooth, and firmly bonded with the base.
• It is easy to construct in the position with complex shape, and the effect is better than that of coiled material.
• Liquid cooling construction, simple and convenient operation.
• It has long service life, weather resistance, aging resistance, oil and acid-base resistance, and wide application range, and can be used on the upstream and downstream water surfaces.
