DSM Neocryl XK-190 is a one-component self-crosslinking waterborne acrylic emulsion in the Neocryl XK series, designed for outdoor decorative and multi-substrate flexible environmentally friendly coatings. It is a milky-white liquid with a solid content of 45%, a pH of 8.7, a viscosity of 200 mPa.s (25°C) and a minimum film-forming temperature of <0°C, featuring excellent flexibility and outdoor durability, forming transparent films, strong adhesion to plastic, wood, metal and other substrates, good weather resistance and water resistance,
Flexibility & Crack Resistance - Forms flexible films, resisting substrate deformation and temperature changes, reducing coating cracking, suitable for outdoor temperature difference environments.
Outdoor Durability & Stability - Excellent weather resistance and water resistance, UV aging resistant, not easy to lose luster, fade and chalk after long-term outdoor use.
Strong Adhesion to Multi-Substrates - Strong adhesion to plastic, wood, metal and other substrates, meeting the needs of multi-material outdoor and decorative coating.
High Transparency & Natural Texture - Forms highly transparent films, presenting the natural texture of substrates, enhancing the decorative effect and texture level.
Plastic Outdoor Decorative Paints - Used for ABS, PP and other plastic outdoor products, featuring good flexibility and weather resistance, improving the outdoor service life and aesthetics of products.
Waterborne Wood Matte Clear Coats - Used for outdoor wood decoration, transparent and flexible, weather and water resistant, protecting wood while presenting natural textures.
Metal Light Anti-Corrosion Paints - Used for light anti-corrosion of outdoor metal products, strong adhesion, weather and corrosion resistant, extending the service life of metal products.

Q1: What is the primary function of Neocryl XK-190 in waterborne coating formulations?
A: Neocryl XK-190 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 Neocryl XK-190 differ from non-associative thickeners like CMC or HEC?
A: Unlike cellulosic or non-associative acrylic thickeners, XK-190 functions through transient hydrophobic associations in aqueous systems, delivering superior shear-thinning behavior, enhanced film integrity, and reduced sensitivity to electrolytes and surfactants commonly found in modern paint formulations.
Q3: Can Neocryl XK-190 be used in both interior and exterior coatings?
A: Yes—it is widely employed in both interior and exterior waterborne architectural coatings, including flat to semi-gloss paints, due to its compatibility with common pigment dispersions, binders, and co-thickeners, as well as its contribution to balanced open time and scrub resistance.
Q4: What is the recommended addition method for optimal performance?
A: For best results, XK-190 should be added during the let-down stage, typically after pigments and primary binder, under moderate agitation. Pre-dilution with water or compatible solvent may aid dispersion, and pH adjustment to 8.0–9.5 prior to addition supports full thickening development.
