MEKO Replacement | VALIREX NOVAL NEXT
MEKO-Free Anti-skinning Agents & Isocyanate Blockers
If you’re looking for a one-to-one replacement for MEKO-based anti-skinning agents and isocyanate blockers, then our VALIREX NOVAL NEXT product line offers the right solution. This portfolio provides high-performance alternatives to traditional MEKO products, with the added benefit of causing minimal health and environmental impact.
Regulatory and Sustainability Concerns for MEKO (methyl ethyl ketoxime)
MEKO is commonly used in alkyd coating technology as an anti-skinning agent. It prevents the formation of a surface film on the product while it is stored in a sealed container.
This skin could mix with the remaining paint, potentially impacting its quality and performance. Additionally, MEKO is known to act as an isocyanate blocking agent in polyurethane coatings and adhesives.
Despite its effectiveness, MEKO has faced regulatory pressure in numerous countries due to its toxicity profile. As of November 2023, EU REACH has legally classified MEKO as Carcinogenic Category 1B.
As a result, its usage is heavily restricted, including a ban on consumer and professional applications.
Moving Beyond MEKO Products – VALIREX NOVAL NEXT
VALIREX NOVAL NEXT serves as the perfect MEKO substitute for solvent-based coatings. It is a high-performance, less toxic alternative. VALIREX NOVAL NEXT can be dosed as a one-to-one replacement for MEKO and is compatible with a wide variety of paint driers.
However, note that skinning performance depends on various factors beyond the type of anti-skinning additive and drier used, such as the type of resin, pigments, and other additives.
At Umicore, we are committed to helping alkyd paint suppliers discover the right formulation solutions and transition to safer alternatives without compromising performance.
