Epoxy tar adhesive/grout
epidermix® 316 is a pour grade, solvent free, amine cured epoxy tar slot sealing compound. Designed for sealing of electric cables, signal switches and mechanisms placed under trafficable surfaces in concrete and asphalts.
For the grouting in and maintenance of road traffic cables, signal mechanisms, inductance transmission loops and lighting systems set into saw cuts and cable slots in:
- Road traffic surfaces
- Airport runways
- Taxi ways
- Hard stands, aprons and cargo areas
- Airport runways and taxiways recessed guide light channels
- Installation of automated gates, booms and barriers
- Cold applied, no heating equipment required
- Resistant to certain solvents and chemicals
- Pourable and self levelling
- Fast setting and curing time – minimises down time
Any surface to which epidermix® 316 is to be applied to must be clean, dry and mechanically sound. If slot has been formed by means of saw cutting, all dust, dirt, laitance, slurry and water must be removed from the joint. The joint must be flushed out with clean water, and standing water must be flushed out with dry, oil free compressed air and allowed to dry.
When applying epidermix® 316 to steel, aluminium and coated alloys, the surface must be clean, free of rust, oil, millscale and any other foreign matter. For maximum adhesion bare metal surfaces should be abraded by means of sand blasting.
Encapsulated cable slot, and guide light cavity (no movement)
epidermix® 316 can be applied directly into the prepared saw cut or cable slot, fully encapsulating the cable when no movement is anticipated.
Isolated cable slot and guide light cavity (movement)
When cables are required to be isolated from the epidermix 316 slot sealing compound. The cable should be laid loose at the bottom of the slot or recess and covered with duracord that is a minimum of 25% bigger than the slot. The epidermix® 316 is then applied over the backing cord to fill the slot or cavity.

Protection of Adjacent Surfaces
Masking tape applied to the adjacent slot edges will protect them from over run, spillage and smearing and enable slots to be finished to a neat line. The masking tape should be applied after the slot or light cavity has been prepared, prior to the product being poured. The masking tape must be removed after all finishing/tooling has been completed but before the material has set.
If the geometry of the slot or cavity dictates that a backing rod is required or if the cable needs to be isolated from the sealing compound , insert the appropriate size duracord, into the slot to the correct depth.
epidermix® 316 must be mixed in the correct proportions and packs should not be split or diluted. Separately stir the contents of both containers well, then add the activator to the base component and mix thoroughly with a slow speed drill or mixer with a flat paddle.
In slots and cavities: By volume, dependent on slot or cavity geometry.
As an adhesive: Spreading: 1 L/m2/mm thickness.
After mixing pour the epidermix® 316 into the prepared slot utilising an appropriate pouring device with spout, nozzle or funnel.
If required the surface of slot or cavity can be smoothed of with a clean putty knife or spatula, as soon as the epidermix® 316 has been poured.
Tools and mixing equipment should be cleaned immediately after use and before the material has set, with abe® super brush cleaner followed by washing with soap and water.

Handling & Storage
This product has a shelf life of 12 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® 316 is toxic. Always ventilate the working area well during application and drying. Avoid flames in the vicinity of uncured epidermix® 316. Always wear gloves when working with the material and avoid excessive inhalation and skin contact. If material in splashed in the eye, wash with copious quantities of clean water and seek medical attention.
