Product Description
CS-12 (film-forming additive) CAS: 25265-77-4
Synonyms: 2, 2, 4-trimethyl-1, 3-pentanediol mono (2-methylpropanoate),
Molecular Formula: C12H24O3
CS-12, which is developed by Guangzhou DongHuang Chemical Technology Co, Ltd, is a film-forming additive widely used in latex architectural trade paints. It is a slow evaporating solvent and difficult to dissolve in water. They provide many excellent properties to the coating: High scrub resistance, color development, stable property, ect. It serves as an excellent coalescing aid for emulsion polymers with good hydrolytic stability, can be used in different kinds of latex paints, such as high pH latex coatings. After adding CS-12 into latex coatings, it was adsorbed by emulsion polymers and soften them, so that it can complete the fusion process when drying the film. Because of the excellent hydrolytic stability, CS-12 won't be absorbed with water when painted on porous material.

Operating and instruction
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 (P, A, V, C, will be different ), will also require different CS-12 dosage.
2) In general, the dosage of CS-12 depend on the 3~8% solid content of emulsion. Larger dosage will obtain better results. It dose not affect the stability of the emulsion when not exceed 12% of solid content of emulsion.
3) It 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 gel 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.
