How much do you know about wood coatings additives?
BASF formulation additives demonstrate superior performance in solvent borne and UV-curing applications in the furniture and flooring market. Read this short Q&A to test your knowledge on additives in the wood coatings market.
Q&A
Q: Performance Properties: Viscosity and settling are always a concern when using UV matting agents. What type of additive would be useful to combat this issue?
Q: Material Consolidation: To move from solvent borne to water borne or UV applications, the choice of additives is very important. What characteristics are needed in an additive to achieve greater flexibility?
A: Water compatibility - Efka® SL 3299 can be used in solvent, solvent-free and water-based applications. As formulations are converted from solvent to water, additives like Efka SL 3299 do not need to be replaced, providing flexibility in evolving formulations and the added benefit of simplifying your toolbox.
Q: Spray Applications: For vertical spray applications of wood coatings, which rheology modifiers give you ease of use with high clarity and high sag resistance?
A: Polyamide wax - To address the challenge of sag resistance in vertical spray applications, low shear rheology modifiers are required. For clarity and ease of use, Efka® RM 1469 is a great solution. It's a modified polyamide wax that does not require high temperature activation.
Q: Anti-Migration: What aspects of an additive would be useful in terms of anti-migration?
A: Crosslinking functionality, high molecular weight, and degree of branching within the polymer. Migration of additives is a concern as it can lead to undesirable appearance, loss or change of surface and film properties, and environmental issues. Crosslinking functionality in additives allows them to be chemically bound in the coating. Efka® SL 3299 is a surface modifying wetting agent with OH functionality, allowing it to react into polyurethane coatings, eliminating migration and adding longevity.
