BASF Attagel50colloidal clay

Basf company produces ATTAGEL50 thixotropic thickener, in aqueous and solvent system has very good thickening effect, it is dry powder, the average particle size of 0.1 (including its main ingredients for aluminium magnesium silicate, formula for mgo style 3 · 15 alo3 · 8 sio2 · 9 h2o it through special processing, can be applied to emulsioni paint, paint, ink, adhesives, putty and sealant, toothpaste, cleaning supplies, etc.Thickening, anti-hanging effect is obvious.

Product advantages:

1. The thixotropic thickening effect is obvious, preventing pigment deposition, and improving the drying and shrinkage of paint film.

2. Anti-flow hanging and anti-splash, improve the uniformity of paint film surface.

3. It is not sensitive to water and has anti-bacterial property, so as to maintain the stability of the product in the long term.

4. Chemical inert, not sensitive to PH changes.

5. Improve the coloring power and hiding power of pigment.

Product use

A. waterborne system:

In latex paint, the most common use of ATTAGEL50 is to work with a small amount of cellulose thickener.The concentration of ATTAGEL50 is 0.5-2.0% (weight ratio), and the amount of cellulose is about 1/4 to 1/6 of the amount of ATTAGEL50.Using 300 2.5% hydroxyethyl cellulose (HEC) or hydroxypropyl methyl-cellulose (HPMC) aqueous solution, with 20 ATTAGEL50 dry powder and 70 water mixing, the thickened pre-dispersible pulp can be prepared.This pre-disperse slurry is diluted to the coating to achieve the desired effect.

B. Solvent based system.

ATTAGEL50 instead of organic clay used in solvent free system can significantly reduce the cost of coating in the solvent system used in ATTAGEL50 need a small amount of cationic surfactants to appropriate wetting and dispersing, surface active agent shall, first of all, to join in the paint, then add the pigments and other components, add ATTAGEL50 after fully dispersed and scattered.The optimal ATTAGEL50 and table surfactant ratio (about 5:1-10:1) should be adopted to achieve the best results.Various grinding techniques can be used in dispersion.High - speed dispersion is the most commonly used method, grinding can produce excellent dispersion effect.Many customers prepare 12-20%ATTAGEL50 surfactant pre-gel slurry, which can directly add pre-gel slurry to a large amount of paint toppings.And you don't have to apply a high shear, just stir well enough.
