Waterproof coating two-component polyurethane (PU) TF3165

1. Product Overview:

This product is a two-component reactive polyurethane (PU) waterproof coating composed of component A and component B. After mixing, it forms a highly elastic waterproof coating through chemical reaction. The product has excellent weather resistance, high elongation, chemical corrosion resistance, and good construction performance, suitable for waterproof protection of various buildings and engineering structures.

2. Product Features:

(1) Strong weather resistance: The coating has excellent UV resistance, high and low temperature cycling resistance, and is not easily aged, powdered or cracked when exposed to outdoor environments for a long time, maintaining a long-lasting waterproof effect.

(2) High elongation: The coating has a high elongation at break, which is suitable for deformation such as base expansion and settlement, effectively preventing cracking of the waterproof layer caused by structural displacement.

(3) Environmental protection and health: 100% solid content, no organic solvents, and no coal tar components.

(4) Convenient construction: Two components can be mixed in proportion for construction. It has a fast curing speed and can be applied thickly.

3. Physical performance parameters:

Item Specification range Testing standard
Hardness, Shore A 60-65 GB/T 19250
Tensile strength, MPa ≥4 GB/T 19250
Elongation at break, % ≥450 GB/T 19250
Surface drying time, h ≤8 GB/T 16777
Hard drying time, h ≤24 GB/T 16777

4. Precautions for use:

(1) Before use, component B must be thoroughly stirred to ensure the homogeneity of the liquid.

(2) Construction environment: Avoid construction in rainy, snowy, and strong winds above level. The ambient temperature should be between 5-35 ℃.

(3) Safe operation: Operators must wear protective gloves, glasses, and masks.

(4) Disposal: The remaining paint and packaging materials shall be disposed of in accordance with local environmental regulations.

5. Packaging and Storage Transportation:

Packaged in plastic drums, stored in a cool and dry place indoors, with a storage temperature range of 10 ° C to 25 ° C, avoiding contact with water, alcohols, and amine substances. This product is not a hazardous chemical and can be transported by ship, air, etc.

Specification: The net weight of component A per barrel is 20kg, and the net weight of component B per barrel is 20kg.

Shelf life: 6 months in sealed packaging.
