Product Description APPLICATION SCHEDULE Applied by electrostatic spraying gun that can provide negative tension of 60-80 kV. Curing schedule :15 minutes at 180oC (metal temperature )Optimal film thickness : 60 -90 um POWDER PROPERTIES Specific gravity : 1.25 - 1.75 (depend on colors)Particle size distribution(Laser Particle size analyser) : Less than 5% above 100 um 50 - 65% above 32 um : Average particle size : 35 - 45umCOATING PROPERTIESThe following are typical properties determined on 0.8 mm gauge degreased galvanised steel .Film thickness (ISO 2178) :60 - 90 μmGloss (ISO 2813, 60o) :> 40% Adhesion (ISO 2409) :GT= 0Pencil hardness(ASTM D3363 ) :2H Direct and reverse impact (ASTM D2794) :> 50kg.cmSalt spray Resistance ( ASTM B117, 1000hrs)(Maximum undercutting ,1 mm ): No blistering Humidity Resistance (ASTM D2247,800 hrs):No blistering or loss of adhesionChemical Resistance:Resistant to some common inorganic acids, bases and salts, organic acids and solvents.SUBSTRATES AND PRE-TREATMENT In order to obtain optimal anti-corrosion properties, it is recommended to apply a chemical pretreatment prior to powder coating application. Ferrous metals(cold rolled steel, cast iron etc.): Iron or zinc phosphatation Zinc surfaces(galvanized steel, zinc alloy) : Chromatation or zinc phosphatation Aluminum alloys : Chromatation STORAGE Should be stored under dry conditions with good ventilation at a temperature not exceeding 30 C.Storage period recommended should not exceed 6 months,in case exceeding 6 months without affecting their free flowing properties, the powder will still have optimal characteristics.Should be protected from excessive heat,humidity,water and contamination with foreign materials such as powder, dust, dirt, etc.Any leftover powder should be kept in an appropriate area that is cool and dry. Do not expose to the air too long as the powder properties may deteriorate with the moisture.
