epidermix 372 FS

Any surface to be treated must be clean, sound and dry. It must be free of foreign matter such as oil, grease, paint, dust, debris of preparation and any other form of contamination. Smooth surfaces should be roughened by some appropriate method.

Preparation of specific surfaces: 

• Cast concrete and pockets in concrete – free of all laitance and shutter release.
• Drilled concrete and rock – if wet drilled, free of all traces of dry slurry; if dry drilled, free of all drilling debris.
• Fibre cement – free of all dust.
• Smooth steel – free of millscale, rust and other foreign matter. Ideally abrasive blast cleaned.
• Deformed and threaded steel – free of oil, grease and rust.
• Aluminium – free of grease. Abrade and degrease. Bond immediately.
• Stainless steel – is not a candidate material.
• Timber – roughen by rasping. Oily woods (e.g. teak) should be acetone washed.
• Glass – detergent wash, clean water rinse, alcohol rinse.
• Glass fibre laminates – abrade to expose fibres and solvent wash.
• Ceramic (unglazed) – contamination free and dry/SSD.
• Stone – free of contamination.
• Rubbers – degrease and roughen.
• Thermoplastic plastics (except polystyrene) – are not candidate materials.
• Polystyrene – must be free of foreign matter.

No priming required.

Mixing Ratio: 2 base to 1 activator by volume. Carry out mixing on a flat clean surface, such as a board or plate.

Set up carefully measured quantities (2 volumes base and 1 volume activator) of each component, side by side on the mixing plate. Do not mix until application site operations are ready. Use separate tools to remove each component from its container thus preventing contamination. With putty knives, paint scrapers or similar flat tools, mix the two components until a completely homogeneous material results. The larger the volume of the mix the longer should be the mixing time. If a filled material is required, add the filler only after complete mixing of the base and activator has been achieved. Remove mixed material to a clean surface and carry on mixing to ensure no unmixed material from the first mixing area is incorporated in the final product.

Application rate: 

• In general 1 litre of mixed epidermix^® 372 FS covers 1 m² to a thickness of 1 mm.

Note: This information makes no allowance for site wastage.

Maximum application rate: 

• AS AN ADHESIVE: Use thinnest possible film allowing for full wetting of adherents.

Application by putty knife or trowel.

AS AN ADHESIVE: Mixed material should be spread onto the face of one adherent, thickly enough to extrude when both faces are mated. Bonded
mating faces must be kept under compression until the adhesive layer has set. On heavy assemblies excess adhesive should be removed immediately
and may be reused on other units. In delicate work such as jewellery bonding, extruded material should be left to obtain initial set and then cut
off with a fine sharp blade. If prevention of staining of faces is important a release agent should be used, care being taken to see that it does not affect
the mating faces.

Tools and mixing equipment should be cleaned immediately after use and before material has set with abe.^® super brush cleaner followed by washing with soap and water.

Allow a minimum of 4 hours and a maximum of 12 hours before commencing with epoxy coatings.

10°C to 40°C. 

General-purpose thixotropic epoxy adhesive.

The adhesive/grout will be epidermix^® 372, a two-component, solvent-free, thixotropic, polyamide cured epoxy system applied in accordance with the recommendations of a.b.e.^®. The compound will have a 7 day compressive strength of 70 MPa and a lap shear strength on grit blasted steel of 16 MPa.

epidermix^® 372 is supplied in 90 ml and 500 ml.

This product has a shelf life of 24 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.

Wet epidermix^® 372 is toxic but non-flammable. Ensure the working area is well ventilated during application and drying. Always wear gloves when working with the material and avoid excessive inhalation and skin contact. If material is splashed into the eye, wash with plenty of clean water and seek medical attention.

Cured epidermix^® 372 is inert and harmless.
