ACRYSOLTM RM-8WE

ACRYSOL™ RM-8WE Rheology Modifier is a product offered by Dow Coating Materials, designed for use in water-based coatings to improve their performance and environmental friendliness. Here's a summary of what it is and how it works:

What is ACRYSOL™ RM-8WE Rheology Modifier?

ACRYSOL™ RM-8WE is a non-ionic urethane type polymer that functions as a rheology modifier in water-based coatings. Its purpose is to enhance the rheological properties of paints and coatings, enabling better flow and sag resistance while maintaining a balance between viscosity and application properties.

Key Features:

1. Environmental Benefits: It is formulated to be used in low VOC (volatile organic compounds) or solvent-free interior and exterior paints, contributing to environmental friendliness.
2. Mid-Shear Builder: It has a rheology profile similar to that of ACRYSOL™ RM-8W but without the intentional addition of tin compounds during production.
3. Easy Incorporation: Supplied as a low viscosity liquid, it is simple to add to formulations without pre-blending with other rheology modifiers.
4. Compatibility: Works well with dispersing agents and can be used as a co-thickener in various formulations to achieve desired viscosity balances.
5. Wide pH Range: Being non-ionic, it can be used over a broad pH range, typically between 7.0 and 9.0 for optimal stability and rheology control.

Formulation Guidelines:

• Can be added to the mill-base or letdown portion of the formulation.
• Should not be pre-blended with other rheology modifiers before adding to the paint.
• Compatible with dispersing agents like OROTAN™ series and can be used with pigment dispersants for low odour paints.

Rheology Profile:

• Mid-shear HEUR (hydrophobically modified polyethylene oxide urethane) type thickener with a balanced rheology that facilitates paints with an outstanding balance between flow and sag resistance.

Interactive Effects of the Paint System:

• The efficiency of ACRYSOL™ RM-8WE Rheology Modifier is influenced by factors such as latex polymer particle size and distribution, latex polymer composition, surfactants, and co-solvents.

Handling Precautions:

Before using, consult the Material Safety Data Sheet (MSDS) / Safety Data Sheet (SDS) for details on product hazards, handling, and storage recommendations.

Storage and Disposal:

• Store in tightly closed original containers at recommended temperatures.
• Dispose of in accordance with local or national regulations. Empty containers may still contain hazardous residues.

Product Stewardship and Customer Notice:

Dow emphasizes product stewardship and encourages customers to consider the environmental and health impacts of their manufacturing processes and applications. They offer technical support and safety data sheets for proper use of their products.
