Purpose

WellCoat AT A135 Synthetic Thickener is used as a rheology modifier in the manufacture of various aqueous-based paintwork materials. Due to the presence of hydrophobic groups, a mesh structure with hydrophobic domains is formed when interacting with water, providing high-quality interaction with pigments and hydrophobic binders. This interaction makes it possible to effectively regulate the viscosity of the composition and improves the filling of paintwork materials. WellCoat ATA135 is non-toxic and highly resistant to bacterial action. The product reduces splashing during application and allows you to get a smooth and even coating, increases the paint covering power, improves the filling of paintwork materials.

Recommendations to application

For the best introduction of WellCoat AT A135 into the system, it is recommended to dilute one to three parts of water. Optimal thickening is achieved in alkaline conditions (pH = 7-10). The recommended dosage is 0.3-1.5% by weight of the composition, depending on the type of binders, fillers and dispersants used and should be determined by laboratory tests. WellCoat AT A135 must be stored in closed containers, avoiding exposure to low temperatures, the optimal temperature range is from +5 to 40 °C. A film may appear on the surface of the product due to evaporation of water during storage. This phenomenon does not affect the functionality of the product, the film can be removed by filtration. Salts of some metals may cause turbidity of highly concentrated WellCoat AT A135 solutions.
