Single-component Moisture Cured Polyurethane Waterproof Coat

Description

Single-component moisture cured polyurethane waterproof coating can be applied on wet surface and complicated projects, forming a seamless, strong bonding,elastic and flexible waterproof film.

Features

1. Packed in one component and ready to use. It avoids the quality instability induced by the inappropriate compounding of two or three components.
2. The performance is stable. It possesses the property of aging-resistance, acid and alkali resistance, fatigue resistance as well as high and low temperature resistance.
3. Environmentally-friendly.
4. Good leveling property, simple construction. After coating, it will react with moisture in the air and cure, forming a compact, seamless, tough and high elastic waterproof film.
5. It can be compounded with high polymer membrane and self-adhesive modified bitumen waterproof membrane to form a compound waterproof system.


Application

1.Non-exposed roof
2. Underground
3. Indoor bathroom and kitchen
4. Non-potable water waterproof construction
5. Bridge and tunnel

Application Guidance
 1. Leveling
 Substrate should be smooth and firm.
2. Cleaning
No garbage, floating pulp on the substrate, keep it dry.
3. First coating
The first layer should be very thin, covering the substrate is enough, less than 0.5mm thickness.
4. Second & Third coatings
Apply the second layer provided the first layer is cured. Coating direction is vertical to the first one and then the third layer's direction is the same as the first one. 
Recommended usage: 1.65 kg/sqm, 1mm thickness, total thickness no less than 1.5mm

Packaging
20kg/barrel
Shelf life
Do not store product exposed to weather and sun. When kept in a cool, dry and protect area, sealed pail have a 12-months shelf life.
