Liquid (Non-Structural) Epoxy Adhesive.

Two-component, solvent-free, polyamide cured epoxy.

General purpose liquid epoxy compound. Adhesive for various substrates. Binder for epoxy mortar. Crack injection compound. Coating for expanded polystyrene, primer for epoxy mortar, fibre glassing compound.

Advantages
  • Solvent free.
  • Easily applied liquid.
  • Can be injected.
  • Mix with aggregates to form mortar.
  • Liquid general purpose adhesive.
  • Coating for polystyrene.
Surface Preparation

Any surface to be treated must be CLEAN, SOUND and DRY. It must be free of foreign matter such as grease, oil, old paint, dust, debris of preparation and any other form of contamination. Smooth surfaces should be roughened by some appropriate method. epidermix 365 will not adhere to most thermoplastics and should also not be used to bond stainless steel, glass or non-ferrous metals.

Bonding / Priming

Self priming.

Mixing

Stir each component separately and then add the activator to the base and stir with a flat paddle for at least FIVE MINUTES. It has been found that mechanical mixing gives better dispersion than manual mixing.

A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a paddle. If only part of a kit is to be used add  1 volume of activator to 1,5 volumes of base. Measuring must be accurate and separate stirrers and containers used for proportioning each component. If being used as a mortar binder combine base and activator as above and when fully mixed add in slowly, with agitation, up to 3 volumes dry, clean, a.b.e.® graded silica sand to give the consistency required. Under no circumstances exceed 3 volumes of silica. If impermeability is a prime requirement, fill in the range of 2,5:1.

Practical Coverage Rates
Adhesive 1 – 4m2/l (dependant on surface texture and porosity)
Crack injection 1 – 4m2/l (dependant on surface texture and porosity)
Tile pointing mortar 1l mixed epoxy liquid yields approx 3L mortar (when mixed 1:3 with a.b.e.® silica sand)
Hold down bolt grout 1l mixed epoxy liquid yields approx 1,9l grout (when mixed 1:1,5 with a.b.e.® silica sand)
Epoxy concrete 1l mixed epoxy liquid yields approx 3,4l epoxy concrete (when mixed with 2l a.b.e.® graded silica sand and 2l 10 – 19mm washed and dried stone)
When using epidermix 365 as a grout, the hole diameter should be 1,3 – 1,5 times the diameter of the steel.  When metal is being grouted, its surface temperature should not exceed 25ºC at the time of grouting.
Grouting – Quantity Calculations

The quantity of epidermix 365 required may be calculated from the formula:

0,8 (D + d) (D – d)HN = litres required
1000 

where D = diameter of hole (in cm)
d = diameter of metal (in cm)
H = depth of hole (in cm)
N = number of holes

This gives the total number of liters of grout required, without any allowance for wastage.

When a grout comprising of 1 volume epidermix 365: 1,5 volumes of abe® silica sand is used, epidermix 365 will comprise 60% of the final volumes. Diameter ratio of hole to rod should ideally be 1,3:1.

 

Safedeck System

Where used as a bonding coat in the safedeck system, the concrete surface should be primed with abe.®cote 386. This must be left overnight and then overcoated with epidermix 365. The grit layer which provides the non-slip finish must be evenly broadcast into the wet epidermix 365 at the rate of approximately 1 kg/m2.

This is left overnight and excess, loose grit swept off the following morning whereupon sealing with the selected top coat system may proceed. abe.®cote 320 or abe.®cote 441 are usually selected as the finish coat on safedeck systems. Always use abe.®cote 441 if the system is going to be exposed to ultra violet light.

Application

epidermix 365 may be applied by brush or short fibre roller when it is used as a primer. Its resulting film must be overlaid with epoxy mortar while still wet or at least tacky. epidermix 365 when used as an adhesive, should be applied by brush. The face of the one adherent should be lightly coated and all excess compound scraped off.

Apply a full coat of epidermix 365 to the second adherent and sandwich the faces together maintaining necessary compression across the bond line. Remove all extruded material immediately and take care to pre-mask any areas which could be disfigured by excess adhesive. Strip masking as soon as adhesive flow ceases. epidermix 365 mortar is normally trowelled into place onto a coat of still wet epidermix 365 primer. Plastic wrapped shutters will be needed on vertical faces to retain the mortar until it sets.

Horizontal mortars may also need shuttering depending on the particular use of the material. If a very smooth open face is required work with a steel float moistened with white spirit to achieve the final polish. Details of crack injection procedures will be found in the relevant technical data sheet.

Health & Safety

Uncured epidermix 365 is toxic and flammable. Always ventilate a working area well during application and curing. Avoid naked flames in the 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 advice.

Cured epidermix 365 is inert and harmless.

When transporting liquids and semi liquids by aircraft, ask for material safety data sheet.
