Batimix Epoxy Primer 152 T1

Description

BATIMIX Epoxy Primer 152 T1 is a pre-tinted, low viscosity solvent-based epoxy primer. It is used to seal and prime concrete and other substrates before the application of liquid resin systems. It is absorbed into the substrate, sealing off surface defects, which may cause bubbling on the final surface finish.

Main Purpose

BATIMIX Epoxy Primer 152-T1 is a semi-clear two-pack epoxy resin of low viscosity. It is used to seal and reinforce porous concrete before the application of other resin-based flooring products.

Features

BATIMIX Epoxy Primer 152-T1 adheres strongly to concrete, with failure occurring within the concrete rather than the epoxy system on test. It adheres well to concrete, metal, wood, and most flooring compositions.

Health and Safety

BATIMIX Epoxy Primer 152-T1 is not a hazardous material. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Application & Dosage

Pour the full content of the hardener container into the full content of the resin container, and mix thoroughly with a slow speed electric stirrer for a minimum of 2 minutes. The mixing ratio A/B is 2/1 (where A is the resin component, and B is hardener).

BATIMIX Epoxy Primer 152T1 must be applied on sound and thoroughly cleaned substrates free of oil, dust, loose particles, and paints. The traces of mould joints must be leveled. All surfaces should be free from water prior to application. Admissible substrates include concrete, metal, wood, and most flooring compositions.

Apply by brush or roller, working the resin well into the surface. On porous surfaces apply further resin until the surface is completely wetted out. Push out the resin as thinly as possible, just leaving enough resin on the surface to give a wet appearance. Allow curing hard before application of any appropriate resin system.

The temperature during application should be between 5 and 35 °C, and the maximum moisture content (relative humidity) should not exceed of 50%.

BATIMIX Epoxy Primer 152T1 is generally applied at a rate hovering from 100 to 150 g/m², depending on porosity of substrate. In general, the following coverage rates are applied:

Rough porous concrete = 175 g/m² Average surface finish = 125 g/m² Smooth finish = 100 g/m²

Compatibility

BATIMIX Epoxy Primer 152-T1 is compatible with and adheres to an extensive range of epoxy resin and polyurethane resin flooring systems.
