Overview
EFKA-3033 is a silicone-based leveling agent developed to address surface defects in coatings and inks. Manufactured by EFCA Additives (now part of BASF), it is widely recognized for its ability to improve flow properties without causing foam or intercoat adhesion issues. This additive is particularly effective in solvent-borne systems, where it migrates to the surface during film formation to create a uniform interface. Its non-reactive nature makes it suitable for diverse formulations, including polyurethane, alkyd, and acrylic coatings.
Physical and Chemical Properties
As a modified polysiloxane, EFKA-3033 exhibits low surface tension (approximately 20-22 mN/m), enabling it to rapidly homogenize coating surfaces. The additive is chemically inert and thermally stable up to 200°C, ensuring performance in high-temperature curing processes. Its viscosity ranges between 500-1,000 mPa·s at 25°C, facilitating easy incorporation into formulations. The product is typically used at 0.1-1.0% of total formulation weight, with optimal dosage determined by substrate and application method.
Main Applications
In automotive OEM and refinish coatings, EFKA-3033 eliminates cratering caused by substrate contamination. For wood coatings, it enhances leveling in high-gloss polyurethane finishes while preventing fisheyes. The additive is equally valuable in industrial maintenance paints for metal substrates, where it improves wetting on rusty or oily surfaces. In printing inks, it ensures uniform pigment distribution and reduces dot gain in gravure applications.
Safety and Storage
EFKA-3033 requires standard chemical handling precautions—use nitrile gloves and safety goggles. Though not classified as flammable, storage areas should be well-ventilated and away from oxidizers. Unopened containers have a shelf life of 24 months when stored below 30°C. Crystallization may occur at low temperatures; gently warming to 40°C with agitation restores homogeneity without affecting performance.
B2B Procurement Guide
When sourcing EFKA-3033, verify the supplier's certification as an authorized distributor to ensure product authenticity. Bulk purchases (200kg drums) typically offer 10-15% cost savings versus small packaging. Request batch-specific certificates of analysis and regulatory documentation (REACH, RoHS compliance). For global procurement, confirm whether the supplier can handle hazardous goods shipping documentation if required by local regulations.
