BORCHI® GUARD T LP 2399 is a MEKO- and oxime-free anti-skinning agent for oxidatively cured solvent-based coating systems, printing inks, and pigment pastes. It improves storage stability by preventing skin formation on the surface while material is still in the container, maintaining stability with minimal loss of dry. Efficient at low dosages, it achieves excellent dry times across a variety of primary driers. Additionally, it controls surface-dry retardation and keeps the film open longer, allowing deeper oxygen penetration into lower film layers to promote thorough drying and improve flow and leveling properties.
