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.
