Oxime-Free Anti-Skinning Additives Support Alkyd Reformulation
Need to Know
- The two additives are designed for solvent-based alkyd resin systems and drier packages as alternatives to traditional oxime-based anti-skinning agents.
- The manufacturer reports skin prevention at reduced dosages while maintaining favorable drying performance and coating hardness.
Borchers, a Milliken brand, has introduced Borchi Guard A and Borchi Guard T, two oxime-free anti-skinning additives for solvent-based alkyd coatings.
The additives were developed as formulators evaluate alternatives to methyl ethyl ketoxime (MEKO), 2-pentanone oxime (2-PO) and related chemistry amid evolving regulatory requirements. Borchers says the products provide effective skin prevention at reduced dosages compared with traditional oxime-based anti-skinning agents.
The additives are designed for broad compatibility across solvent-based alkyd resin systems and drier packages. The company also reports fast dry times and favorable hardness across a broad range of formulations.
