ADVANTAGES
USAGE
DE-181 can be added directly in powder under high shear condition. The addition is recommended to be before grinding procedure to get the best effectiveness. Addition level is commonly 0.2%~1.0%. In low polarity system such as mineral spirit, if polar activator is added, better efficiency can be achieved.
Dosage of polar activator is suggested to be 10%-20% of DE-181 by weight.
