Features & Benefits
- Two-component polyamide adduct-cured epoxy paint
- Cures to a flexible, well adhering coating
- Contains aluminium
- Sealer for Hempadur systems on aluminium/zinc metal sprayed substrate in atmospheric exposure.
- Service temperature - Maximum, dry exposure only: 140°C
Application
- Remove oil, grease and other contaminants by suitable detergent cleaning
- Remove salts, detergents and other contaminants by high pressure fresh water cleaning
- Mixing ratio Base 17949 : Curing agent 97290 (2 : 1 by volume) Stir well before use
- Thinner: Hempel's Thinner 08450
- Apply with brush, roller or airless spray (Nozzle pressure: 175 bar [2500 psi] Nozzle orifice: 0.017-0.019")
- Pot life: 4 hours @ 20°C
- Dry film thickness: 25 micron
- Wet film thickness: 80 micron
- Coverage: 12 m²/L
- To avoid condensation, apply on a clean and dry surface with a temperature that is at least 3°C above the dew point
- Surface temperature must be above 0°C during application and curing
- Optimal paint temperature for proper mixing, pumping and spraying is: 15-25°C
- Surface dry in 60 minutes @ 20°C
- To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing
- If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion
- Metallised surfaces should be overcoated before exposure to open air conditions
- The surface must be dry and clean prior to application
- Epoxy coats have an inherent tendency of chalking in outdoor exposure. This does not affect the performance of the coating
If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C.
Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval. For best performance, avoid excessive film thickness.
