EPOXY TAR MASTIC
Two-component, solvent-free, filled, amine-cured epoxy tar mastic.
Uses:
- Bonding and filling of most construction materials, including concrete to asphalt, especially kerbstones, and cuts in roadways
- Tack-bonding of rubber. Bridge bearing pads to concrete stoolings
- Bonding metal framed cats eyes to road ways (tarmac and concrete)
- Good gap filling properties
- Not for structural ℓoading, or use in drinkable water
Advantages
- High strength, multi use
- Resistant to motor fuels, oils and water
Surface Preparation
Any surfaces to be treated with epidermix® 315 must be LEAN, MECHANICALLY SOUND and DRY. The surface must be free of all
preparation debris prior to placing the compound.
Bonding / Priming
Self bonding.

Application
Rough apply the mixed epidermix® 315 to the prepared surface using a trowel or putty knife. Work the material so as to ensure thorough wetting of the surface.
A final, fair fi nish may be obtained by trowelling off the surface of the still uncured epidermix® 315 with a water-wet tool.
Cleaning
abe® super brush cleaner before dried/cured.
Protection on Completion
Against traffic and spillage until cured.
Temperature and Relative Humidity
See properties during application and properties of cured material.
Model Specification
Two-component epoxy tar paste for bonding and filling of many construction materials.
The bonding material shall be epidermix® 315, a two component, solvent free, amine cured, epoxy coal tar system, applied in accordance with the manufacturers recommendations, a.b.e.®. The compound shall have a 7-day compressive strength of 20 MPa.
Packaging
epidermix® 315 is supplied in 500 ml and 5l yield 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® 315 is toxic but non-flammable. Always ventilate the working area well during application and drying. 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.
Harmless, but not for contact with food or drinkable water.
When transporting ℓiquids and semi ℓiquids by aircraft, ask for material safety data sheet.
