TS-201 Environmentally friendly polyurethane waterproof coating (911) is formed from two components’ reaction, component A is polyurethane prepolymer obtained from the reaction of polyether polyol and isocyanate, component B is from the reaction of various auxiliaries, such as anti-ageing agent, vulcanizing agent, crosslinking agent, etc. When use, we mix A&B at a certain proportion, after curing, it forms a elastic, strong, and durable waterproofing coating film.
Product characteristics
It can be constructed on complex base surface to form integral seamless waterproof coating.
Green environmental protection, ambient temperature solidification, liquid construction, easy operation;
It has good weather resistance, high elongation and excellent waterproof performance.
Scope of application
Basement waterproofing, subway, tunnel, pipe gallery, pit, pool, trench, toilet and bathroom waterproofing; expansion joint, construction joint, deformation joint waterproofing; concrete structure of flat roof, slope roof, planting roof waterproofing.
Usage method
1. Base surface requirements: construction base surface requirements are flat, dry, no damage, no dust, no oil pollution;
2. Ingredients: According to the proportion of component A: component B = 1:2 (or the proportion provided by the manufacturer), first put component A into the container, then add component B, mix evenly, then use it; in order to cut off moisture in the base and improve the bonding strength between the base and the coating, a layer of base treatment agent can be coated;
3. Construction method: Rubber scraper is used to scrape the mixed uniform coating on the base surface during construction. The coating thickness is generally 1.0-2.0 mm, and it is constructed 2-3 times. After the previous coatings are dry, the next construction can be carried out.
4. In order to increase the cohesion between the waterproof layer and the protective layer, before the final coating is solidified, sprinkle clean coarse sand or fine stone on its surface, which can enhance the cohesion between the protective layer and the waterproof layer; avoid raining before the coating is dry; the joint must be painted evenly and full, and the weak part can be pasted with fiberglass cloth to increase the strength.
