Epimastic 3100

A high build surface tolerant polyamide adduct cured epoxy anti-corrosive primer for underwater areas.

Berger Epimastic 3100 is a tough, hard wearing maintenance primer/sealer coat for steel substrates and provides outstanding fresh and seawater resistance. Suitable for use in immersion applications. It has excellent anti-corrosive performance with outstanding tolerance to moisture. It is also used in situations where blasting is impractical and only power or hand tool surface preparation is possible. It is able to cure under adverse conditions, at temperatures down to 8°C and provides good hardness and abrasion resistance. An ideal tar free replacement for coal tar epoxies.

Surface preparation

• Remove all wax, oil and grease by solvent cleaning in accordance with the guidelines given by SSPC-SP1. Soluble salts, dirt and dust must be removed by dry brushing and freshwater washing. Remove scale by chipping, needle gun or spot blasting. Any loose or flaking coatings should be taken back to a firm edge.
• Mechanically clean the surface using hand or power tools to a minimum standard of St 2 (ISO 8501-1:1988) or SSPC-SP2 taking care to avoid polishing the surface.
• Where necessaries remove weld spatter and round off all rough weld seams and sharp edges to smooth surface.
• For best performance abrasive blasting should be used. Abrasive blast clean to a minimum surface preparation standard of Sa2½ (ISO 8501-1:1988) or SSPC-SP10, with an average surface profile of 50 – 75 microns.
• Apply Epimastic 3100 immediately after blasting to prevent oxidation and recontamination of the steel surface. In case of oxidation or recontamination, re-blast to the required standard.
