SR-H85
Organobentonite thickening rheological agent
主要用途：
Suitable for anti-corrosion paint, industrial paint, such as polyester, acrylic resin, epoxy resin, polyurethane and other systems.
使用方法：
The product is added after mixing the solvent and part of the resin into the container, dispersed at high speed for 5 minutes, added activator, dispersed at high speed or grinding.
In order to maintain better results, the amount of highly polar solvent in the mixed solvent generally cannot exceed 30% of the total solvent system, the addition amount of general paint 0.5-2.5%, the recommended selection of methanol/water (95/5) ethanol/water (95/5) as the activation agent is generally 30-50% of the amount of SR-H85. If you choose to use acetone/water (95/5) as the activator,the recommended dosage is 50-60% of the added amount of SR-H85.
