Ⅰ. Specification
Appearance: light yellow viscous liquid Total solid: 35±2% 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).
