Low viscosity crack injection compound.

Two component, solvent free, low viscosity modified epoxy.

Uses

A crack injection compound for cracks between 0.10 and 0.05 mm in width. It is also suitable for gravity feed applications subject to crack width and depth, for better penetration consider the injection process. May also be used as primer for epoxy mortars and electrical encapsulation.

Advantages
  • Stabilizes cracks in concrete.
  • Insulates and tamper proofs electrical fittings.
  • See properties of dry film.
Surface Preparation

Concrete should be clean and dry. Surfaces should be sound enough to provide sufficient strength for bonding of injection nipples and surface seal.

Bonding / Priming

Self-priming.

Mixing

Add the entire contents of the activator can to the base material. Stir for five minutes using a flat paddle. If only a small quantity is required, pre-stir the contents of each container using separate flat paddles. Pour two volumes of base component and one volume of activator into a separate, clean container. Mix together for five minutes using a flat paddle.
