Bilt Hamber Epoxy Mastic 1L - Black

Bilt Hamber Epoxy-Mastic is an ultra-durable, high solids, heavy duty protective coating for steel and alloys. It provides the ultimate corrosion protection to chassis, vehicles, plant and machinery.

Made in the UK with superior epoxy and low surface tension wetting hydrocarbon resins.

When compared to competing formulations this material will outperform other Epoxy-Mastic and moisture cure urethane products.

Our epoxy mastic is further combined with pure zinc phosphate to provide unparalleled rust and corrosion proofing.

• Two-pack product
• Long pot life.
• Coverage: 10m per two litres at 100 micron dry film thickness.
• Corrosion Inhibitor additives.
• Suitable for long term immersion in marine environments.

How To Use:

Epoxy-Mastic can be applied to mechanically cleaned rusted steel, or steel cleaned by grit blasting.

Where steel is clean of rust and corrosion, application of Electrox zinc rich primer will dramatically increase the long term performance and provides protection far beyond epoxy mastics applied directly to steel.

On previously corroded steel that is not fully clean, increased protection can be afforded by the use of Hydrate-80.

Steels should be degreased and free from loose scale and debris. Aluminium, stainless steel and galvanised steel should be etch-primed with Etchweld self-etching primer.

Mix 4 parts of 66MAS to 1 part 66 ACC The former is the mastic base, the latter is accelerator or hardener.
Stir thoroughly and apply by brush or roller. Thin and clean brushes with Epoxy-Mastic Thinner.

Hard dry in seven hours depending on temperature and conditions, drying is retarded below 10 degrees C.

Coverage 10m per two litres at 100micron dry film thickness.

All epoxy mastic coatings can chalk on long term exposure to UV light. To prevent this aesthetic deterioration overcoat with suitable UV stable topcoat. Epoxy-Mastic is inert to the vast majority of top coat systems.
