DSM Neocryl XK-12 from DSM's Neocryl series self-crosslinking modified acrylic emulsion range is a high-performance water-based resin designed for wood coating in industrial and architectural fields. As an anionic modified acrylic copolymer emulsion, it can achieve self-crosslinking without additional crosslinking agents, with excellent blocking resistance and chemical corrosion resistance after film formation
Self-crosslinking without additives - Can complete crosslinking and film formation without additional crosslinking agents, simplifying the formula system and ensuring batch performance stability.
Excellent protective performance - Outstanding water resistance, chemical corrosion resistance and damp-heat resistance, effectively resisting daily environmental erosion, with long-lasting and reliable coating.
High-end decorative performance - High gloss and good transparency, excellent wetting of wood pores, highlighting the natural texture of the substrate, no yellowing in QUV test.

Q1: What is the primary function of Neocryl XK-12 in waterborne coating formulations?
A: Neocryl XK-12 is a hydrophobically modified acrylic associative thickener designed to provide rheology control—particularly high-shear viscosity and sag resistance—while maintaining good flow, leveling, and spatter resistance in low-VOC, waterborne architectural and industrial coatings.
Q2: How does XK-12 differ from cellulosic or polyurethane thickeners?
A: Unlike cellulosics, XK-12 offers superior water sensitivity resistance and reduced roller spatter; compared to polyurethane thickeners, it delivers more consistent viscosity build across varying pH and electrolyte conditions, with lower susceptibility to microbial degradation in the final formulation.
Q3: Is Neocryl XK-12 compatible with common co-thickeners and additives?
A: Yes—XK-12 is generally compatible with other associative thickeners, non-ionic surfactants, defoamers, and dispersants used in waterborne systems. However, optimal performance requires careful sequencing during let-down and compatibility testing with cationic additives or high levels of certain biocides.
Q4: What are key handling and storage recommendations for XK-12?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from freezing and prolonged exposure to direct sunlight. Avoid contamination with incompatible materials; always pre-dilute with deionized water before addition to formulations, and use clean, non-reactive equipment for transfer and dosing.
