Properties and applications
1/ Colorless, transparent liquid, b.p.255℃, specific gravity: 0.945-0.955 (20/20℃), freezing point -50℃, refractive index 1.4423 (20℃).
2/ C-12 is an ideal water-based coalescent agent, and has good compatibility to emulsion polymers and reduce the MFT/Tg. Mean while, C-12 has proper evaporation speed, and can be easily absorbed in the surface of polymer without affecting the stability of emulsion particles.
3/ C-12 is appropriate for various kinds of water-based coating systems such as emulsions, adhesives synthesized from methacrylate, cinnamene and vinyl acetate.
4/ C-12 can be used directly. After appropriate churning, add C-12 into the water-based coating systems.
Dosage： It is recommended that C-12 dosage is equivalent to 5-10% of the emulsion content and not exceed 12%.
