Coating Printing Thickener
BS-201

 

Ⅰ. Specification

Appearance: light yellow viscous liquid
Total solid: 352%
Viscosity: 1-5Pa.s
pH: 4-12, optimum at 6-7
Thickening effect (2%): rotational viscosity ≥30Pa.s.

Ⅱ. Characteristics

* High efficiency. 2-3 parts of BS-201 equals to 100 parts of Acrapon A.
* Low cost. Cost can reduced by 2/3. Also negates use of white kerosene.
* Easy to use: add calculated amount of BS-201 into water, stir for 2 minutes. Sotck paste is stable within 15 days.
* Improved printability.
* Can be used in combination with self-crosslinking adhesives, eg. BS-101.

Ⅲ. Use

* Add calculated amount of BS-201 or BS-201 stock preparation (1:1, water) into color paste, and stir (1400rpm).
