Inorganic Phosphate Zinc-rich Coating(zinc rich)

GZH203 Inorganic Phosphate Znic-rich Coating Composition:inorganic phosphate,silicate,ultra-fine zinc powder,solvent,accessory ingerdients Characteristic:catholic protection,chemical corrosion,shielding function,excellent weather,water resistance,oil resistance,solvent resistance,is the updated products of SIPZC coating. Use:The paint is applied to the steel corrosion under the environment of PH5-9. Basic Standard Item Standard 1.Mixing ratio glue:curing agent:zinc powder=1:0.8:3.2(weight ratio) 2.Specific gravity 1.9g/ cm3 3.Thickness dry film:50μm/layer wet film:100μm/layer 4.Coating rate theoretical dose:270-290g/ m2 Actual value:it is related to the surface treatment,enviroment and way of constraction 5.Storage temperature 25°c 6.Storage period glue,zinc powder:12 months curing agent:6 months 7.Resistance to salt spray no peeling,blistering,rusting in 5000h 8.Heat resistance no layer-off,cracking,shedding(400±10°c,4h) 9.Attachment strength ≤1 rate 10.Impact resistance50kgf.cm 11.Pencil hardness>2H Constraction data 1.Way of painting brush painting,spraying,roll coating 2.Diluent special diluent 3.Constraction temperature 0°c-40°c 4.Drying time surface drying time:≤30 min;actual drying time:≤8h 5.Recoating timethe shortest recoating time of the coating is 8h(25°c),the shortest recoating time of the matching paint is 24h,the longest recoating time of the matching paint is 7days 6.Matching paint epoxy,chlorinated rubber,bitumen,polyurethane,ethylene,fluorocarbon 7.Surface treatment remove the rust of the steel surface to make it reach the standard of ISO Sa2.5 Constraction conditions 1.relative humidity ≤80% 2.steel’s surface temperature 3 degrees higher than dewpoint 3.wind ≤3 4.the air should be clean,and without oil and water 5. Rain, snow and ice days or occasion of sand is not suitable for construction.you should stop painting on occasion of mentioned conditions,and protect the painted part well,also you should check if the film is normal before next construction,or you should deal it before next process.After painting you should keep it from water and fog and paint the intermediate paint and primer as soon as possible.
