Description
Product Description
STWD8006 one component transparent PU wood structure coating takes high performance single component PU prepolymer resin as raw material, curing after reaction with air moisture. The coating film contains large amount of urea bond, urethane bond and hydrogen bond, with excellent physical property, stable chemical resistance to acid, alkali, salt and oil, with superior waterproof, mildew resistance, pest control and anti-white ants performance.
Features and advantages
*coating film is smooth and full, compact, with high decoration effect.
*high adhesive strength, abrasion resistance and impact resistance
*good pest control, anti- white ants effect
*excellent waterproof and mildew resistance effect
*excellent anti-aging, no powdery, crack or peel off after long term outdoor application
*excellent chemical resistance such as acid, salt, alkali etc.
*green and eco friendly, do no harm to environment and human body during and after application.
*it is water based coating, pollution free to the environment, safe for the workers application
*one component material, easy to apply, without mix and save labor cost.
Typical use
Anticorrosion waterproof protection of stainless steel metal surface, buildings, park landscape, municipal engineering and other wood structures.

Application environment
Relative temperature: -5~-+30ºC
Relative humidity: RH%:35-85%
Dew point: ≥3ºC
Application tips
Recommended dft: 40-80 um
Re-coating interval: 4-24h
Coating method: airless spray, air spray, brush, roller
Application tips
Apply the products at above -10ºC. The temperature of raw material shall has 3ºC higher than dew point, to prevent the condensation phenomenon.
STWD suggests to pour out the limited material each time to prevent moisture cure. Any material leftover shall be stored in separate container for future use. Don't pour the material to original buckets. Seal the package immediately after pour out the limited material. Reduce the time of contacting with air is necessary for it will react with air moisture.
Use out of the material within one hour or the viscosity will be increased then affect application.
Use ace tone or MEK to clean the tools before the products fully cured.
