Product Characteristics

Description

Hempel Multi-purpose Epoxy High-build Paint 500 (Summer) is a fast-drying high-solids epoxy resin coating. It provides hard abrasion-resistant protection and long-lasting barrier protection in the coating system, suitable for severely corrosive environments.

Recommended use

When fast handling and short overcoating times are required, Hempel Multi-purpose Epoxy High-build Paint 500 (Summer) is recommended as a high-build intermediate coat in high-performance coating systems. Due to its ultra-fast drying (twice that of similar products), it is very suitable for projects requiring fast production. This product can also be used as a self-priming surface-tolerant coating layer and a topcoat in heavy-duty coating systems.

Service temperature

• Under dry conditions: maximum service temperature 120 °C [248 °F].

Product features

• Fast recoat.

• Crack-resistant at high film thickness.

• Low VOC.

• Due to its long pot life, it is suitable for application in hot climatic conditions.

• Surface tolerance.

VOC content (after mixing the multi-component paint)

Subject to specific legislation; see the explanatory notes on the Hempel website hempel.com or your local Hempel website. VOC values may vary with colour; refer to Section 9 of the Safety Data Sheet. This product complies with the VOC requirements of national mandatory or recommended standards; consult the company representative for details.

Handle with care. Before and during use, observe the safety labels on the packaging and paint containers and comply with all local and national safety regulations. Consult the Hempel Safety Data Sheet and Product Data Sheet for the product at all times.

For professional use only.

Surface Preparation

Cleanliness

• Remove oil, grease and other contaminants by cleaning with a suitable cleaner.

• Remove salts, detergents and other contaminants by high-pressure fresh water washing.

New construction

• Abrasive blast clean to Sa 2½ (ISO 8501-1) / SP 10 (SSPC) minimum.

- Stainless steel, aluminium and other non-ferrous metals and alloys: use a non-metallic blast medium (e.g. corundum, garnet).

• Sweep-blast to obtain a uniform fine sharp profile, with no bare spots.

• Remove dust, blast abrasives and loose material.

Maintenance and repair

• Spot abrasive blast clean to Sa 2 (ISO 8501-2) / SP 6 (SSPC) minimum.

• For small areas where abrasive blasting is not possible, clean by hand or with power tools.

• Water jetting to Wa 2 (ISO 8501-4) minimum.

• Maximum flash rust grade FR M (ISO 8501-4).

- Stainless steel, aluminium and other non-ferrous metals and alloys: use a non-metallic blast medium (e.g. corundum, garnet). Sweep blast to obtain a uniform, dense, well-defined profile without bare spots.

• Feather the edges into sound surrounding coating.

• Remove dust, blast abrasives and loose material.

Roughness

• Surface roughness Medium (G) (ISO 8503-2).

Pot Life

Recommended method

If brush or roller application is used, several coats may be required to achieve the specified dry film thickness. Spray parameters are indicative and may be adjusted to suit site conditions. Pressure figures apply to the material at 20 °C. (*For other application methods, consult the company representative.)

Film thickness

Depending on the end use and service area, the product may be specified at film thicknesses other than those indicated. This will alter the spreading rate, drying and curing times and recoat interval. To achieve optimum performance, avoid excessive film thickness.

Application conditions

• The ideal paint temperature for proper mixing, pumping and spraying is 25 °C [77 °F].

• The surface to be coated must be clean and dry, and its temperature must be at least 3 °C [5 °F] above the dew point to avoid condensation.

Relative humidity

• During application, the relative humidity must be below 85%.

• During curing, the relative humidity must be below 85%.

Notes

• This product requires heavy-duty spray equipment; hoses should be as short as possible.

• Thermally sprayed coatings shall be overcoated before exposure to open air.

• When recoating porous substrates, a mist coat technique is recommended.

Drying and recoat

Product compatibility

• Previous coat: none, or according to Hempel's specifications.

• Subsequent coat: according to Hempel's specifications. Recommended products:

Drying Time

Measured at 150 µm dry film thickness under standard conditions; see Hempel's explanatory notes.

Recoat

Hempel's specifications supersede all guidance shown in the recoat table.

Extendable* Depending on the actual exposure conditions, the coated surface may be recoated after an extended time. Contact your local Hempel representative for advice.

For products of the same generic chemical composition, recoat times are for reference only.

For further information, refer to Hempel's specifications.

Drying conditions

- To achieve the stated drying times, adequate ventilation during application, drying and curing is essential.

• In accordance with Hempel's specifications.

Recoat notes

• If the maximum recoat interval is exceeded, the surface must be roughened to ensure intercoat adhesion.

• The surface must be dry and clean before application.

Others

• Epoxy coatings have an inherent tendency to chalk when exposed outdoors. This does not affect coating performance.

• Hempel's specifications supersede any recommendations in the Product Data Sheet.

Storage

Storage conditions

- Store the product in accordance with the Safety Data Sheet, label and local regulations. Keep containers in a dry, cool, well-ventilated place away from heat and sources of ignition. Keep containers tightly closed. Handle with care.

Carbon footprint

Carbon footprint is based on a 1 µm dry film thickness formed over a surface area of 1 m².

The scope includes raw materials, transport to the Hempel factory, the Hempel production process, and any volatile organic compounds (VOC) emitted during and after use of the product.

Calculated based on the standard colours defined in this PDS. Values may vary with colour.
