Metal Primer - Epoxy WB - Water Based - CPR 410 - CPRL

Description

Metal Primer – Epoxy WB

CPR 410 Metal Primer – Epoxy WB is a two-pack, water-based, epoxy, anti-corrosive primer designed for the protection of steelwork. Whilst optimum performance will only be achieved by applying to well-prepared substrates CPR 410 Metal Primer – Epoxy WB will adhere well to minimally prepared surfaces. CPR 410 Metal Primer – Epoxy WB has been formulated to provide fast touch dry times and rapid hardness development.

Directions for Use

Surface Preparation

Steel/Galvanised steel: Any rust, mill scale and other contaminants should be removed by grit-blasting to Swedish Standard Sa 2.5.
Reduced levels of surface preparation, e.g. wire brushing to remove loose rust, are permissible but may lead to lower performance levels.

Mixing

Mix the two components together, preferably by mechanical means, until a uniform consistency has been achieved.

Application

Apply the material by brush, roller or airless spray, at a nominal rate of 4-6m² per litre per coat.

Equipment Cleaning

Clean equipment with CPR 200 Tool Clean Solvent immediately after use.

Curing

CPR 410 Metal Primer – Epoxy WB will be touch dry following 1-2 hours cure @ 20ºC in conditions of good ventilation.
Following 4 hours cure @ 20ºC the material will be hard dry, and then maybe re-coated.
Allow 7 days cure@20ºC for optimum chemical resistance and mechanical properties.
The primer may be allowed to age and weather for a maximum period of up to 2 months prior to top coating.

Storage and Shelf Life

Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C.
Avoid frost.
CPR 410 Metal Primer – Epoxy WB has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with the manufacturer’s instructions.

Packaging

CPR 410 Metal Primer – Epoxy WB is supplied in 1L and 5L.

Coverage

1 litre of CPR 410 Metal Primer – Epoxy WB will be sufficient to treat 4-6m² of surface, achieving an overall dry film thickness of 100-150 microns.

Technical Data

Limitations

Do not apply to wet surfaces.
Do not apply at temperatures of 3°C or less.
Owing to its comparatively weak cohesive nature, the primer is not suitable for overcoating with very high build systems such as CPR 820 Waterproof Deck System – Epoxy HB (danger of ‘splitting’ of the primer and subsequent delamination of the system.

Health and Safety

Avoid skin and eye contact with the material.
Wear gloves and goggles.
Wash off splashes immediately with soap and water.
Any eye contamination must be rapidly irrigated with copious amounts of clean water, and immediate medical attention sought.
