colloidal attapulgite powder as paint additive/thickener/thixotropic agent

Product Overview

Description

attapulgite powder paint additive

  

It is a special formulated and customized product with high viscosity based on the natural attapulgite clay and by special processing technology. It is characterized with strong adsorption and cohesion forces, and has good suspending and colloidal properties.

 

excellent leveling/thixotropic/thickening agent for paint/coating

comparing with additives for paint and coating, such as calcium carbonate light,cellulose, our attapulgite powder additives makes paint and costing

1.better stabilized feature
2.better colloidity
3.better fluidity
4.better thixotropy

5.lower production cost

 

Characteristics

Natural nano-structures, colloidal performance, light weight, good suspension, roll into a good, good chemical stability, absorption capacity, strong bond, green environmental protection.

=================================================================

Attapulgite is a kind of crystalloid hydrous magnesium-aluminum silicate mineral, having a special laminated chain structure in which there is a crystalline lattice displacement existed. Thus it makes the crystals contain uncertain quantities of Na+, Ca+, Fe3+ and Al, and present in the shape of needles, fibers or fibrous clusters. Attapulgite has very good colloidal properties such as: specific features in dispersion, high temperature endurance, salt and alkali resistance, and also high adsorbing and de-coloring capabilities. Furthermore, attapulgite has certain plastic and adhesive characters. Its ideal molecular formula is:

Mg₅Si₈O₂₀(HO)₂(OH₂)₄•₄H₂O.
