404S Epoxy Metal Primer is a two pack, high solids, epoxy, anticorrosive primer designed for the protection of steelwork, aluminium and galvanising.

Whilst optimum performance will only be achieved by applying to well-prepared substrates, 404S Epoxy Metal Primer will adhere well to minimally prepared surfaces. 404S Epoxy Metal Primer has a long overcoating window and provides excellent corrosion protection.

Typical Properties

Coverage

• 1 litre of 404S Epoxy Metal Primer will be sufficient to treat 8-10m² of surface, achieving an overall dry film thickness of 80-100 microns

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
• New galvanised steel or aluminium may be abraded and solvent wiped

Mixing:

• Pour the contents of the curing agent container into the base container and thoroughly mix, preferably by mechanical means until a uniform colour is achieved

Mixing Ratio:

• By Volume - 4 Base: 1 Curing Agent

Application

• Apply the material by brush, roller or airless spray, at a nominal rate of 8-10m² per litre per coat

Cleaning

• Clean equipment with 109 Tool Cleaner prior to curing of the coating

Curing

• 404S Epoxy Metal Primer will be touch dry following 4 hours cure @ 20ºC in conditions of good ventilation
• Following 6 hours cure @ 20ºC the material may be 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 3 months prior to top coating

Limitations

• Do not apply to wet surfaces
• Do not apply at temperatures of 5°C or less

Storage & Shelf Life

• Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C
• Avoid frost
• 404S Epoxy Metal Primer has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions

Health & Safety

• Avoid contact of the material with skin and eyes
• 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
• Please refer to Material Safety Data Sheet for additional information
• 404S Epoxy Metal Primer shall be applied strictly in accordance with the manufacturer’s instructions
