EPONAL 382

Epoxy primer for waterproofing coating systems

Additional Downloads
MSDS PART A (resin)
MSDS PART B (hardener)
Definitions
PrimerLiquid or paste applied onto a substrate to obtain optimum bonding. It helps regulate the porosity of the substrate (reduce absorption, therefore adhesive usage), increase adhesion to non porous surfaces, improves application properties of later on applied adhesive
Working timeTime between end of waiting time and moment when the application is no longer possible

Uses

EPONAL 382 is a two-component solvent-free epoxy resin used as a primer in waterproofing systems.

Benefits

Solvent-free
Free from aromatic amine and benzyl alcohol
Excellent adhesion to concrete and steel

Consumption:

EPONAL 382: 250 g/m²

Shelf life:

Up to 24 months in the original, unopened containers, stored in a dry place between +15°C and +35°C. The product must be protected from frost as it may cause product crystallisation.

Application

Application conditions

Working temperature: +10° to +25°C

Relative humidity: maximum 80%

Substrate temperature must always be at least 3°C above the dew point temperature during application and cure.

Surface preparation

Preparation should be in accordance with building standards. Surfaces must be clean, sound, dry, of adequate compressive and tensile strength (at least 25 MPa and 1 MPa respectively after 28 days cure for new concrete). They must be free from laitance, clean and free from dust, grease, curing compounds or any other contaminants that would inhibit proper bond. Depending on surface condition and type, substrates are treated by abrasive blasting, mechanical planing, scabbing, sandblasting, high pressure water washing or chemical stripping. After mechanical treatment of a subfloor, thoroughly vacuum all dust.

Steel surfaces should be sanded or abrasive blasted to a white metal finish, then degreased with MEK (Methyl Ethyl Ketone).

Application of EPONAL 382

Slowly add the hardener into resin (components A + B) while mixing, mix thoroughly for 2 to 3 minutes with an electric drill and mixing paddle (speed: not more than 300 rpm in order to avoid air bubbles inclusion). Apply immediately the mixture with a roller onto the substrate.

After full cure of EPONAL 382 (i.e. 24 hours at +20°C), EPONAL 384 binder for reinforced lining systems can be applied either immediately or after several days (at least 7 days) without any specific preparation.
