Hempel epoxy zinc-rich primer 172CE base: 172C7 hardener: 971CE Overview: Hempel epoxy zinc-rich primer 172CE is a two component epoxy zinc-rich paint. It can be cured to form tough wear, excellent weather resistance film. Provide local mechanical damage parts of the cathodic protection. Uses: As with a "VOC applicability" feature universal long-term primer, used as epoxy paint, vinyl paint and acrylic paint primer coating for steel supporting surface moderately to severely corrosive environment. Zinc content in line with SSPC-Paint20 second class second grade requirements, compliance with ISO12944-5 standards. Physical parameters: Color / Color: Red Grey / 19830 Paint: Flat Volume solids: 65 + 1% Theoretical coverage: 13.02 / liter (50 micron dry film) Flash point: 24 ° C Weight: 2.7 kg / liter Dry to touch: 1 hour (20 ° C) to fully cure: 7 days (20 ° C) VOC: 332 g / liter content (VOC): Construction Description: Surface treatment: with a suitable cleaning agent thoroughly remove oil and grease. High pressure fresh water washed away the salt and other contaminants. Abrasive blasting to Sa2.5 level, the surface was a sharp shape, equivalent Rugotest No.3, Keane-Tator Comparator's 2.0G / S, 2S, or ISO comparison plate grade (G). NOTE: 2004/42 / EC: Product undiluted diluted to 15% (by volume) Phase II, 2010 172CE19830 332 g / l 410 g / l 500 g / l Other Color products VOC, please refer to the MSDS. Note: If the device is used as a high temperature corrosion protection coating independent space, pay close attention during the sabotage can not let any water vapor to penetrate into, this is to avoid at elevated temperatures resulting "wet etching." WEATHERING / temperature: This product also has a natural tendency of epoxy coatings, and exposure to outdoor easy powder and the temperature rises, the more susceptible to mechanical damage film thickness and chemical exposure: depending on the purpose and use of the area use non-recommended film thickness. The most typical dry film thickness in the range of 40-50 microns, but the construction may be 15 microns (additional dilution) - 50 microns. This will alter spreading rate, influence the amount of diluent required drying time and recoat interval. (Dry film thickness range does not consider the correction factor listed in ISO19840 rough surface.) Mixing: In order to re-disperse any given substance may sink after storage, and before that must be thoroughly mixed with the curing agent stir the base material. After mixing, in order to maintain a uniform mixing paints, stirring was continued still important. It is particularly important in a lot of dilution and / or construction period, the highest zinc sedimentation rate long stoppage. Repainting Note: If more than the maximum recoat must roughening the surface to ensure intercoat adhesion. The pollution of the environment enough to use surface must be washed with high pressure fresh water clean, let it dry before recoating. In addition, application of hard brush to remove zinc corrosion products (white rust). Gary | ??
