Wood finishes: in unsaturated polyesters, e.g. UV-cured, EFKA-3031 improves slip and smoothness of the surface, and does not influence curtain stability when applied by curtain coating. The sensitivity to air-draughts when sprayed or poured will be reduced by EFKA-3031. Metal coatings: EFKA-3031 improves levelling and mar-resistance and acts as an antiblocking agent. This is particularly advantageous in PUR systems based on hydroxyacrylics. Due to its high surface activity, EFKA-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-2020 and EFKA-2022 should be added.
