Features:
* Can use 20-50% less to achieve low MFFT;
* Improve coating rheology and pigment wetting;
* Easy to add in low shear mixing;
*Minimum water solubility improves distribution performance;
*Good compatibility with latex particles;
* Improve open time to enhance film formation;
* Improve the color development of the coating, with minimal impact on gloss;
* Improve film hardness without cracking;
* Improve scrub resistance;
*Resistant to hydrolysis, so it can be used in high pH emulsions and alkaline substrates.
Dosage:
Add 5-10% of the amount of emulsion in the formula, Dosage does not exceed 12% of the amount of emulsion.
