  December 2013Revision of October 2013 DESCRIPTION  Inorganic Zinc Silicate Primer  PRINCIPALCHARACTERISTICS  – >85% zinc in dry film – Provides outstanding corrosion resistance – Abrasion resistant – Resistant to dry film temperatures of up to 750°F – Recommended for ISO 12944 C5I and C5M Conditions COLORANDGLOSS  GreenFlat BASICDATA Volume solids 63% ± 3% (based on applied film, including porosity)VOC* 4.1 lbs/gal (491 g/L)*  For compliance with regulations which require < 420 g/L, Dimetcote 9VOC can be specified interchangeably.For compliance with regulations which require <340 g/L, Dimetcote 9H can be specified interchangeably. RecommendedDry film thickness (per coat) 2 - 4 mils (50-100 microns)*  Applications up to 6 mils are acceptable with random spot readings up to 8 mils. For high temperatureapplications, a maximum of 3 mils is allowed. Theoretical Spread Rate @ 1 mil dft 1,011 ft 2 /gal@ 3 mils dft 337 ft 2 /galComponents 2 (liquid, zinc powder)Dry Temperature Resistance Continuous — 750°F Color will drift at elevated temperatures. Shelf Life Liquid – 9 months from date of manufacture when stored indoors in the original unopenedcontainer. Storage temperature should be 40-100°F and in dry conditions.Powder – 24 months from date of manufacture when stored indoors in the srcinalunopened container. SURFACEPREPARATION  Coating performance is proportional to the degree of surface preparation.Steel – Abrasive blast to SSPC SP-6 or higher with a 1.5-3.0 mil surface profile. Higher surface profiles up to 5 mils are acceptable, but the product must be applied in athickness great enough to achieve a minimum of 2.5 mils dry film thickness. Apply  Dimetcote  9 as soon as possible to prevent the blasted surface from rusting.Keep moisture, oil, grease, or other organic matter off surface before coating.For touch up and repair, power tool cleaning in accordance with SSPC SP-11 isacceptable. ENVIRONMENTALCONDITIONS  Ambient temperatures 0°F to 120°F (-18°C to 49°C)Surface temperature must be at least 5°F above the dew point temperature.Material temperatures 40°F to 90°F (10°C to 32ºC)Relative humidity 50% minimum*  Work area can be artificially humidified by atomized water spray and/or ponding water under the coated structures. After the film is dry-to-touch, a fine mist may be applied over the coating to expedite curing in low humidity environments. Surface temperature 0°F to 130°F (-18°C to 54°C)Surface temperature must be at least 5°F above the dew point temperature.General air quality Area should be sheltered from airborne particulates and pollutants. Ensure goodventilation during application and curing. Provide shelter to prevent wind from affectingspray patterns. DIMETCOTE  ®  9 page 1/3  INSTRUCTIONSFORUSE Mixing 77 parts liquid :: 23 parts powder by volume.Pre-mix base component with a pneumatic air mixer at moderate speeds to homogenizethe container.Add powder component slowly under agitation until fully mixed. Strain themixture from one container to another through a 30 mesh filter/strainer to remove anyundispersed lumps.Pot life**  Maintain agitation throughout application to prevent settling of the zinc. Protect product from moisturecontamination  Airless spray Standard airless spray equipment, 30:1 pump or larger, 0.019 – 0.023, reversible fluidtip recommended Air spray Thin up to 10%, dedicated equipment for inorganic zinc is highly recommend, standardconventional equipment, 0.070” fluid orifice. A moisture and oil trap in the main line isrecommended. Separate regulators for air and fluid pressure are recommended. Use anagitated pressure pot. Limit fluid hose length to 50 feet.Brush & roll Use a high quality natural bristle. Brush application is only recommended for smalltouch up and/or repair areas. Roller application is not recommended.Repair When dry though, measure the dry film thickness. If film thickness is lower thanspecified, additional material can be applied up 24 hours from the previous application.Thin the second coat with  Amercoat   101 thinner or   Amercoat   930 thinner. Ensure anydry spray is removed.For aged inorganic zinc coatings, spot blast rusted areas in accordance with the surfacepreparation instructions before touching up with  Dimetcote  9. When blasting is notpractical,  Amercoat   68HS or   Dimetcote  302H may be used for repair.Thinner   Amercoat   65 (xylene),  Amercoat   101 (recommended for > 60°F),  Amercoat   930 (recom-mended for applications > 80°F or when dry spray is a problem)Cleaning solvent  Amercoat   12 Cleaner or   Amercoat   65 thinner (xylene)Primers Direct to metalTopcoats  PSX   700,  Amerlock   2/400,  Amercoat   385,  Amercoat   370, others A mist coat / full coat application technique is required when topcoating to preventapplication bubbling. Ensure dry spray is removed from the surface.Product can be un-topcoated in certain applications.Safety precautions For paint and recommended thinners see safety sheet 1430, 1431 and relevant materialsafety data sheetsThis is a solvent borne paint and care should be taken to avoid inhalation of spray mistor vapor as well as contact between the wet paint and exposed skin or eyes. DRY/CURETIMES  Dimetcote  9 @ 3 mils dft and 50% relative humidity*  A MEK rub resistance rating of 4 or higher, indicates the film has cured sufficiently for topcoating. **  Surface must be power washed as needed to remove all surface contaminants including zinc salts. Surfacemust be clean and dry.
