Associative thickener PUR-50

Associative thickener PUR-50

Overview

PUR-50 is a modified polyurethane thickener. It is a water-based non-ionic synergistic rheology modifier that tends to be perfect. It has low VOC, low odor, and excellent high, medium and low shear viscosity distribution. , Whether it is the internal water resistance, color development and other properties of the paint film, or the can opening effect and leveling performance outside the system, it has very excellent performance. It is a perfect supporting product for water-based coatings: we sincerely recommend This product is used in high-end interior and exterior wall coatings.

Typical parameters

Product features

Ø Low VOC, low odor: PUR-50 is a solvent-free polyurethane compound, which can be directly used in water-based coating systems after mixing evenly in a certain proportion.

Ø Improve the can-opening effect: Improving the can-opening effect is the most distinctive and outstanding performance of PUR-50. On the basis of not affecting the leveling of the paint film, the thickness of the paint film, etc., PUR-50 can give the coating system a very beautiful appearance. In-tank fluidity: Even in the acetic acid-acrylic system, which is prone to produce “pseudoplastic” effects, PUR-50 can also give the acetic acid-acrylic system good fluidity.

Ø Excellent construction performance: PUR-50 has excellent performance in high shear viscosity (ICI viscosity). The paint film after construction has excellent flow and leveling properties, and the paint film is thick and uniform.

p>

Ø: No adverse effect on the water resistance, gloss and color development of the coating.

Ø: Anti-microbial decomposition: PUR-50 responds poorly to fungal microorganisms, which can eliminate the influence of most microorganisms on the viscosity of the system and ensure the stability of the system.

Application field

Ø Suitable for water-based architectural coatings, water-based wood paints and other systems.

Ø In fine-grained lipophilic emulsions, it can be used as the main thickener, with better thickening effect and more sensitive response.

Ø It can be used as a synergistic thickener in ordinary pure acrylic, styrene-acrylic or acetic-acrylic systems to reduce material costs and improve the overall performance of the system.

User Guide

Ø Dosage: 0.1-1.0%.

Ø Addition method: After mixing with water at 1:1 or 1:3 and mixing it evenly, slowly add it in the beating stage or paint making stage of paint production.

Ø Product matching: good compatibility with cellulose, alkali swelling and associative thickeners.
