EFKA® SL 3299 is an organically modified polysiloxane, which increases slip, surface smoothness, and gloss. This additive can be used in wood, industrial (epoxy, PUR), and UV curable applications. Due to its excellent compatibility properties, it is very suitable for use in high-gloss clear wood coatings. EFKA SL 3299 also improves the orientation of matting agents in matted wood finishes.

Features & Benefits

• Excellent slip performance at low addition levels
• Superior anti-blocking characteristics increasing surface smoothness and abrasion resistance
• Improved leveling
• Minimal effect on foam stabilization
• No haze in clear coats
• Good compatibility, no negative gloss effect in high gloss systems
• Improve the orientation of metallic pigments and matting agents
• Prevents floating and flooding
• Cross-linkable in PUR or melamine coatings

Sustainability

• Low VOC (<1%)
• ~ 100% solids
• Solvent and solvent-free, water-based systems
