About Foam Thickener Thickenol
Product Description
Thickenol BR 60 is an acid containing, cross linked acrylic emulsion copolymer.
When the emulsion is diluted with water and neutralised with a base, each emulsion
particle swells greatly. The emulsion clarifies under these conditions and becomes
highly viscous
Thickenol BR 60 is effective in improving low shear rate (Brookfield) viscosity,resulting in paints that have highly shear thinning characteristics Paints formulated with Thickenol BR 60 as a sole thickener exhibit a high yield value or gel structure. This structure develops upon removal of shear, hence Thickenol BR 60 are suited to the development of moderately textured paintsOther benefits to the paint manufacturer include reduced roller spatter compared to
high molecular weight cellulosic thickeners
As Thickenol BR 60 is non cellulosic, it offers a high degree of resistance to bacterial and enzymatic attack, resulting in long term paint viscosity stability.
Thickenol BR 60 is recommended for use in textured paints, or as a secondary thickener to control sagging in paints having too much flow.
Thickenol BR 60 can be used in exterior paints but we suggest formulators exercise caution to minimize potential blistering which can occur due to the anionic nature of this product
Use of Thickenol BR 60 alone or combination with other thickeners can yield the following benefits
