AI Overview
Low gloss polyurethane dispersions (PUDs) are environmentally friendly, waterborne coatings featuring low-VOC emissions, providing a, matte, or satin finish. They are used for durable, abrasion-resistant, and chemically resistant coatings on wood, concrete, and plastics. These coatings can be formulated using matting agents (like waxes) or self-matting resins for consistent, low-sheen surfaces.
Key Characteristics & Applications:
- Appearance: Provides a low-luster, non-reflective finish (e.g., satin or matte), ideal for hiding imperfections, dirt, and scratches on surfaces.
- Durability: Offers high performance with excellent flexibility, adhesion, and resistance to abrasion.
- Sustainability: Water-based nature reduces VOC emissions, enhancing safety compared to solvent-based alternatives.
- Applications: Commonly used in wood flooring, furniture, industrial coatings, printing, and packaging.
Types and Formulation:
- Aliphatic PUDs: Often used for high-performance coatings needing UV stability and non-yellowing, such as for hardwood floors.
- Self-Matting PUDs: Specialized resins, such as those from Lubrizol, maintain clarity and chemical resistance without requiring external matting additives, which can sometimes reduce performance.
- Crosslinkers: Often formulated as 2K (two-component) systems for superior hardness, such as CFS-Low Gloss Water Based Urethane.
Commonly Used Additives for Lowering Gloss:
- Waxes/Matting Agents: Incorporated to reduce surface reflectivity.
- Surface Modifiers: Used to adjust the texture and gloss.

What is polyurethane dispersion?
Polyurethane dispersions (PUD) are binary colloidal systems formed by particle dispersions in an aqueous phase, recognized for their low organic content and versatility in coatings, exhibiting properties such as abrasion resistance, adhesion to various polymers, and low-temperature flexibility.

What is the difference between semi-gloss polyurethane and gloss polyurethane?
Gloss Levels for Polyurethane
High-gloss: High-gloss finishes are very shiny and reflective. They enhance the wood's grain and color but show scratches and imperfections more readily. Semi-gloss: Semi-gloss finishes have a slightly less reflective surface, offering a good balance between shine and practicality.
