Product Description

Two-components high-strength polyurethane waterproof coating for high speed railways

 

Reference dosage: 2.0~3.0kg/m2.

A component: 10kg, B component: 20kg.

 

Product Introduction

Polyurethane waterproof coating is divided into two-component, single-component two.
Two-component parts A and B are two groups, and A component is a polyether resin and diisocyanate and other raw materials, after polymerization reaction made containing diisocyanate group (-NOC) of giant carbamate prepolymer; B component is a glue linker, accelerator, toughening agent, tackifier, anti-mildew agent, filler and diluent and other mixed processing.
The single-component is made by mixed polyether for dehydration, and add diisocyanate, and various additives for epoxy modification.
Both two-component and one-component are asphalt-based environmentally friendly materials.

 

Product Characteristics

After curing into a rich elasticity of the overall coating film without joints, the product is a reactive coating, with no coal tar and volatile solvent in the formula, which highly reduces the pollution to the environment and the danger to the person.

 

Construction Method

①Mix A and B components separately according to the ratio on the product package, and use up within 20 minutes.
②Keep the construction site well ventilated.
③Store in a room below 40℃, avoid long-term light and forbid smoke and fire.
④Construction in rain, snow, and wind of grade 5 or above is strictly prohibited.
⑤No construction when the temperature is higher than 35℃ or lower than 5℃.

 

Cautions

①Require solid grass-roots level, no floating slurry, oil stain, etc.

②The construction method of scraping can be used, and the next layer is perpendicular to the direction of the previous layer.

 

Performance Index
