Hempel Hempaprime Multi 500 Winter 45953

Hempel Hempaprime Multi 500 is a two-component, fast drying, high solids epoxy primer that provides hard wearing and long lasting barrier protection. Suitable in specified coating systems for severe corrosive environments.

Best Uses

Hempel Hempaprime Multi 500 is recommended as a high-build, intermediate coat in high performance coating systems where fast handling and short over-coating times are required.

Due to its fast drying - up to twice as fast as comparable, competitive products - the product is excellent for projects where fast return to service is key. Hempel Hempaprime Multi 500 can also be used as a self-priming coat and a finishing coat in heavy-duty coating systems.

This product is intended for all-year application and can be applied at low temperature (down to -10⁰C). It is the standard product for UK environment - Hempaprime Multi 500 Summer is suitable for warmer climates.

Application

New steel: Abrasive blasting to minimum Sa 2½ (ISO 8501-1:2007).

Zinc silicate painted or spray-metallized surfaces: Remove oil and grease, etc. with suitable detergent. Remove salt and other contaminants by (high pressure) fresh water cleaning. Zinc salts (white rust) must be removed by high pressure hosing combined with rubbing with a stiff nylon brush if necessary. It is recommended to recoat spray-metallized surfaces as soon as possible to avoid possible contamination.

Repair and maintenance: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to minimum St 2 (spot-repairs) or by abrasive blasting to min. Sa 2, preferably to Sa 2½ (ISO 8501-1:1988). Improved surface preparation will improve the performance of the product. Feather edges to sound and intact areas. Dust off residues. Touch up to full film thickness. On pit corroded surfaces, excessive amounts of salt residues may call for high pressure water jetting, wet abrasive blasting or, alternatively, dry abrasive blasting, high pressure fresh water hosting, drying, and finally dry abrasive blasting again.

Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. Use only where application and curing can proceed at temperatures above: -10°C. The optimal paint temperature for proper mixing, pumping and spraying is 20°C. In confined spaces provide
adequate ventilation during application and drying.
