Product Description

Product Description

STWD9539 is a single component aliphatic polyurea waterproof anti-corrosion coating material, which has excellent adhesion to various substrates. Due to the unique chemical structure of aliphatic prepolymers, this product not only has excellent high elasticity, high strength, wear resistance, and impact resistance, but also has excellent corrosion and weather resistance. It does not pulverize or change color when used outdoors for a long time, and has good decorative effects.

Product features and advantages
*High solid content, low VOC emissions
*The application method is simple, it can be brushed, roller, air sprayed or high-pressure airless sprayed.
*Good physical properties such as wear resistance and impact resistance
*Excellent waterproof performance
*Excellent resistance to chemical media corrosion, capable of withstanding certain concentrations of acids, alkalis, salts, oils and organic solvents
*Excellent anti-aging, non powdering and non discoloration for outdoor use
*Excellent adhesion force, can quickly and firmly bond to the surface of substrates such as steel, concrete, wood, fiberglass, etc
*Wide temperature range for application, it can be used in environments ranging from -50 ºC to 80 ºC
*The characteristic of single component makes it easy to apply, without the need for mixing, reducing labor costs

Application scopes
Outdoor waterproof and anti-corrosion protection for industries such as petroleum, chemical, transportation, construction, power, and containers. Such as bridge maintenance, building roof waterproofing, water conservancy dams, hydropower station building waterproofing, etc.

Application tips
Recommended dry film thickness: 100-200um (or according to design requirements)
Coating interval: 6-30h. If the coating time exceeds 30 hours or there is dust accumulation on the surface, it is recommended to use sandpaper to polish and clean before application.
Suggested painting methods: airless spraying, air spraying, brush, roller

Application environment
Environmental temperature: -5--35 ºC
Relative humidity: 35-85%
Dew point: when apply on metal surface, the substrate temperature must be 3 ºC higher than the dew point temperature.

Substrate treatment
Metal surface: It is recommended to sandblast to achieve Sa2.5 level according to ISO8501-1 or GB8923 standards.
Concrete surface: achieve a strong, dense, flat, clean, and dry state. There should be no phenomena such as sanding, shelling, cracks and honeycomb. Usually, putty is needed for repair.
Wood surface: clean, dry, without burrs, fragments, and loose debris.
The application treatment of other substrates please consulted with STWD technical personnel.

Application precautions
This product can be used at low temperatures below -10 ºC. When using in low-temperature environments, it is recommended to place the paint bucket in an air-conditioned room for at least 24 hours.
STWD recommends mixing the paint evenly before use, pour out the accurate quantity of material that will use up in one time and seal well immediately. Don't pour the rest liquid to the original bucket.
The viscosity of the coating has been adjusted as needed when this product leaves the factory. thinner shall not be random added by the applicators. Call the manufacturer for the instructions of special thinner if the viscosity changed as the application environment and humidity.
