Structural dry-To-dry epoxy adhesive

Two-component, solvent-free, filled, polysulphide modified epoxy compound.


  • Structural bonding of precast concrete, brickwork, steel, aluminium elements to themselves and in any combination
  • Bonding of fibre cement and unglazed ceramic to most structural materials. Suitable where gap-filling properties as well as adhesion are required

Note: Bonded concrete assemblies should always be used in such a way that there is a compressive stress permanently on the bond line.

  • Structural adhesive for most building materials
  • Use as a gap filler
  • Non-slump
  • High ultimate strengths
  • Non-shrink
  • Mixing control with coloured components
Surface Preparation

The concrete surfaces must be clean, mechanically sound and dry. Surfaces must be free of dust, laitance and any foreign matter as well as cracked or loose stone. Maximum bond strength is only achieved if main aggregate of existing concrete is exposed. This may be done by scabbling, grinding, abrasive blasting or manual chipping. All cracked and loose aggregate must be removed. Steel must be degreased and abrasive blast cleaned to a minimum of Sa 2,5 on the Swedish Code of Practice SIS 055900.

Aluminium must be abraded with medium grit emery paper and washed with abe® thinners no. 3 to degrease the surface and remove all debris of preparation. Apply adhesive as soon as possible after solvent application, to reduce re-oxidation of metal surface.

Bonding / Priming

Self priming.


Always carry out mixing in coolest area available.

Individually stir the contents well of each container. If using an entire kit, remove the lip from both containers using a tin opener. Remove all or the required amount of base and activator from the containers and place them side by side on a clean board or steel plate.

Mix together by using trowels or paint scrapers, until a streak-free, grey material results. This is likely to require at least 5 minutes. Remove mixed material to a clean board prior to placing, to obviate the chance of picking up any unmixed material.


1L/m2 at 1 mm thick.


Apply mixed epidermix® 350 to one working face, placing material in such a fashion that the highest point of the application is in the centre and no depressions exist in the surface of the compound.

Mate the other face to be bonded in the wet adhesive mound so that material extrudes all around the bonded assembly. Scrape extruded material off with a clean spatula off to obtain a neat finish. If an extremely neat finish is required masking tape may be used. Any bonded joint must be kept under full compression for at least 5 days.


Tools, brushes 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.

Protection on Completion

Maintain compression on bonded surfaces until cured. Compression must be maintained permanently for concrete assemblies.

Model Specification

Two component, polysulphide modified, dry to dry, structural epoxy adhesive for precast concrete, steel and brickwork in any combination.The structural adhesive shall be epidermix® 350, a two component, solvent free, polysulphide modified, dry to dry epoxy adhesive applied in accordance with the recommendations of a.b.e.® and have a steel/steel lap shear strength of 11 MPa.


epidermix® 350 is supplied in 500ml, 1 litre and 2 litre metal containers. 

Handling & Storage

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.

Health & Safety

Wet epidermix® 350 is toxic and flammable. Always ventilate the working area well during application and drying. Avoid flames in vicinity. Always wear gloves and eye protection when working with the material and avoid excessive inhalation and skin contact. If material is splashed in the eye, wash with copious quantities of clean water and seek medical attention.

Cured epidermix® 350 is inert and harmless.
