Model Number: P14994 Brand Name: WONCHENG Key Specifications/Special Features: Polyester powder coating main compositionMainly made of epoxy resin and curing agent, leveling agent, pigment, filler and other addictive. It has super chemical resistance and mechanical properties. It can be used in painting those metal products that have special requirement of corrosion resistance, electric insulativity and pliability. Directly outdoor using is not to be suggested. Product processing material blending – melting – hot extrusion – sheeting – cooling – chipping – grinding – sieving – packing order to maintain the relative stability of product, material blending time shall follow the standard to avoid the chemical interaction.Main feature:Produce a uniform, smooth and durable appearanceExcellent corrosion resistance, electric insulationGood stability when stored in the normal temperatureExcellent mechanical property (impact resistance, hardness, flexibility, adhesion and more.)Enhanced coating efficiency due to easily charged particles produced from epoxy resinProne to over-baking or yellowing if curing temperature is too high or curing time too long ProductDetails Type PolyesterPowderCoating ProductCodeNo. P14994 Color RAL3001 GlossLevel Glossy 90% SurfaceFinish Smooth PowderProperty Appearance Finepowder ParticleSize Average32-40μm SpecificGravity 1.3-1.5g/cm3 Coverage 7-8squaremeterperKgat80μmfilmthickness ApplicationRecommendation Applicatoin Corona ApplicationVoltage 60-90KV GuntoComponentDistance 15-30CM FilmThickness 80-90μm CuringTemperature 190℃(Objecttemperature)for15minutes PowderCoatedFilmMechanicalProperties Adhesion Cross-cut(2mm),nolossofadhesion ImpactResistance Direct&Indirect50kg/cm PencilHardness 2H Flexibility 7mmMandrel BendingTest 3mm PowderCoatedFilmChemicalResistance SaltSprayTest 5%NaClSolutionfor1000hours-Nochange AcidResistance 5%HCLfor48hoursdiptest-Nochange AlkaliResistance 5%NaOHfor48hoursdiptest-Nochange SurfacePreparation Allsurfacesshallbedegreasedandpre-treatedforoptimalperformancebeforeapplication Aluminium Yellowchromateorgreenchromate/phosphate Ferrousmetals ZincphosphateorIronphosphate Zinccoatedmetals Zincphosphateorchoromateconversion ExteriorDurability QUVA340Resistance 240hours-70%glossretention StorageStability Storeinventilated,dry,cleanroom,temperature Relativehumidity50-65% Awayfromdirectsunlight,fire,heat Forbestperformance,usewithin6months
