Product Description

Descriptions       
STWD9522 is a single component aromatic polyurea anticorrosion wearable coating, it is compatible with concrete substrate and epoxy, polyurethane coating film. With its unique chemical structure, it has excellent chemical resistance and anticorrosion property, high strength, high elasticity which makes the coating film be abrasion resistance, impact resistance and scratch resistance, to avoid concrete broken from impact and crack power, it is especially suitable for the application of chemical industry, printing and dyeing, pharmaceutical industry. It passed the food class test that is safe for the food processing enterprises application field. It has various color based on the customers' requirements to decorate the application projects.

Product features and advantages.
*High solids, low VOC emissions 
*Easy to apply, brush, roller, air spray or airless spray all suitable.
*High physical properties of wearable, impact resistance and scratch resistance

Application environment
Relative temperature: -5~-+35ºC
Relative humidity: RH%:35-85%
Dew point: the temperature of metal surface must have 3ºC than dew point.

Application tips
Recommended dft: 100-200 (as design requirement)
Re-coating interval: 4-24h, if the interval time exceed 24h or has dust deposited, sand-blasting first and clean well prior to application.
Coating method: airless spray, air spray, brush, roller

Application note
It can be applied in the low temperature below 10ºC. Put the coating bucket into the air-conditioning room for over 24 hours when apply in the low temperature environment.
STWD recommends to agitate the coating uniform prior to application, pour accurate quantity of material to another vessel and seal well immediately. Don't pour the rest liquid to the original bucket.
The viscosity of product is set up in 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.
