EFKA® SL 3031 is compatible with all medium- to high-polarity solvent-based systems.

Wood finishes
In unsaturated polyesters, e.g., UV-curable, EFKA SL 3031 improves slip and smoothness of the surface with no influence on curtain stability when applied by curtain coating. The sensitivity to air drafts when sprayed or poured will be reduced by EFKA SL 3031.

Metal coatings
EFKA SL 3031 improves leveling and mar resistance and acts as an anti-blocking agent. This is particularly advantageous in PUR systems based on hydroxyl acrylics. Due to its high surface activity, EFKA SL 3031 can interfere with intercoat adhesion when recoated without sanding. If air is introduced by the application equipment, small amounts of defoamers such as EFKA PB 2020 and EFKA SI 2022 should be added.

Features & Benefits

• improves mar resistance
• increases slip and surface smoothness
• prevents cratering
• decreases the tendency to pigments’ floating and sensitivity to air drafts
