SR-83
Organic bentonite forgeneral purpose
主要用途：
Paint, ink, sealant, grease, putty and other fields.
使用方法：
The application of the product does not require heating dispersion, to obtain the best gel efficiency is to prepare pre-gel, gel preparation method:
A, solvent or mixed solvent (85 ~87%)
B,SR-83(10%)
C, polarity activator(3~5%)
Mix A first, add B at low speed, disperse at high speed for 5 minutes, then add C, and continue to disperse for 10 to 20 minutes.
The required polar activators are: methanol/water (95/5), ethanol/water(95/5), acetone/water(95/5), and the amount of addition can be appropriately reduced as the polarity of the solvent increases
The amount of SR-83 added to the system is generally 0.2~2.0%(weight ratio).
It is worth noting that increasing the dispersion speed and extending the dispersion time will improve the efficiency of using SR-83.
