Features and benefits
? Because the bubbles mixed by mechanical agitation are in a high viscosity or solvent-free system, polysiloxane defoamers are difficult to eliminate. STA-0512F can inhibit the mixing of air, reduce the generation of air bubbles, and help the bubbles to escape and crack. , So as to achieve better bubble breaking effect;
?Especially has a very good defoaming effect on primers with high powder content, without affecting recoating;
? STA-5012 has good compatibility, can be matte finish and color paint。
Application range
? Acrylic resin, nitro lacquer, UV curing system, two-component polyurethane, epoxy resin, alkyd resin, baking system, etc.
Added amount
? It is recommended that 0.2-2% of the total system is added before grinding.。
Packaging specifications
? 25KG drum
Precautions
? Pay attention to sealing and low temperature storage. During operation, avoid direct contact with skin and eyes. Do not contaminate this product with other products and containers. Please test spray before each batch.
