Colloidal silica for water-paint
1, overview and feature
The colloidal silica for water-paint, an excellent in-organics film former, can be widely applicable to various water-based paint, stone like paint or the emulsion etc.has a function to facilitate filming which don’t change with the temperature. There’s the following fine effect after the colloidal silica mixed with paint: a, faster for the filming speed of the paint. b, hardening of paint-coat. c,waterproof,wash resistance and pollution-proof.

3, Attention
A, It's advised for quantity added to the paint to 15-25% of emulsion.
B, TUS-3 is a new product that is further improved on the basis of TUS-2, it has a better calcium ion stability and enhanced effect after mixing with the emulsion.
C, It is not suitable for mixed with vinegar, organic silicone emulsion.
D, After add this, products such as slight fall yellow, film former showed slightly muddy is normal, and similar organic silicone emulsion.
E, On the choice of auxiliary materials, please choose non-ionic products as far as possible, don't choose cationic products.
F, There’ll be rapid thickening reaction once cellulose material meet with it, which can be back to normal with continue to stir.
G, We can debug the compatibility stability of emulsion samples provided if the customer necessary.
