AT-70 base swelling Thickener 

 AT-70 is acrylate, methacrylate copolymer made of crosslinked polymer emulsion thickener. AT-70 is an acidic group of the alkali-soluble thickener, the viscosity is very low in acid medium, but the availability of a high alkaline medium viscosity. AT-70 high molecular weight, thickening ability, good anti-settlement and mildew, easy to use. AT-70 can improve the coating's low shear viscosity and improve the splash and sagging.

 Use 

 For interior and exterior latex paint, water-based ink, textile coating and mortar, pigment printing paste, pressure sensitive adhesive emulsion, 
 Thickening silicone defoamers. 

 Recommended method 
 1 ﹑ thickened with ammonia will be transferred to the system's PH value 8-9. 

 2, AT-70 with water at 1:1 (or 1:2) ratio were mixed. 

 3, in the low speed state, the dilution of the AT-70 was slowly added to the thickening of the system to achieve the required viscosity, stop adding.
