Application:

CS-12 film-forming additives can be effectively used in vinyl acetate homopolymers and copolymers and terpolymers latex, and acrylic, styrene and vinyl , vinyl acetate latex. When used in latex paint and coating, it has good resin compatibility. As a new type of latex paint film-forming agent, CS-12 is safe, efficient and applicable to all types of synthetic resin. The advantages of CS-12 used in the latex paint is: better coalescence strength at low temperature, better viscosity stability, better color stability; and to improve the application of paint, such as weather resistance, accessibility of polish and clean, repair capacity and color forming ability.

Operating and instructions:

1) For emulsion paint, the dosage of CS-12 mainly depends on the hardness of the emulsion polymer, compared to the soft emulsion (low Tg values), the hard emulsion (high Tg value) need to add more dosage to achieve the same film-forming effect. In addition, using the same formula but different ingredient (different PVC) will also require different CS-12 dosage.

2) Ingeneral, the dosage of CS-12 depend on the 3～8% solid content of emulsion. Larger dosage will obtain better results. It does not affect the stability of the emulsion when not exceed 12% of solid content of emulsion.

3) It's process is very simple when using CS-12 in latex paint production. In principle, it can be added directly at any stage in the production. If the formation occur when adding the material, in advance it could be mix with surfactant and water which is used in latex paint production, then add into the emulsion.

4) If CS-12 is added in two stage, it will fully play its special role:

A)Add half amount of CS-12 in the grinding stage, it would help the wetting and dispersion of pigment and filling.

B) Add another half in paint mixing stage, CS-12 will help prevent bubbles.
