coating material additives, also by is paint material, is types made coating material 辅助材 material, use 时 需 add a small amount of additives to coating material formulation in, can control or reinforcement coating material property can and promote coating film formed. coating material additives large has types different function type type and types type, its in resistant oxidation agent, light stabilizer, dispersant, outer absorption agent, light agent, leveling agent and other different chemical formed separation formed additives. usually coating material formulation in 会包含 multiple additives, generally lower additives use amount in formulation amount amount small 于5%, has lower can can high 达10% above, due to additives value versus for relatively high, in formulation design 时会尽 can can decrease/reduce additives use amount. that 么, additives in coating material formulation in use need attention/notes which issues 呢?

一 additives remove main/primary function outer, meanwhile also has di heavy or more heavy property function. therefore, in design coating material formulation 时就必 must comprehensive 考虑, adjustment formulation in use amount or formulation. 如 light stabilizer add to coating material formulation in not only can as is coating material color or 修补漆 also can for/regarding gloss reduce,, generate cracks, 汽泡,, and color and other has very good made function. therefore, in selection types has additives need separation understanding it property can.

additives 协同效应 is types or multiple additives, through 适当 配 combined use versus effect/influence increase function. 如 resistant oxidation agent can and other additives 如辅助 antioxidant, light stabilizer and anti-static agent and other mixed combined use, mixed combined use rear large large improve/increase coating material application property can.

additives application to coating material most applications made 约, different coating material product types for additives color, odor, resistant property, resistant property, electrical property, heat resistant, resistant property and other has different requirements. outer ring use coating material need has very good weather resistance, heat resistant property and resistant property and other.

selection additives 时应首先 attention/notes additives and resin versus property issues, additives must long stability in powder coating material in, can its has can, therefore generally use additives need has and ring oxygen, poly 醋, acrylic and other resin tool has versus property. generally lower, need comparison material additives and resin versus property, use methods is according to it structure versus property. 例如 leveling agent is powder coating material production in main/primary additives, can decrease/reduce coating film surface force 差, to coating film and remove shrink function, make solid rear coating film obtain slip gloss surface.

certain additives in formulation design 时, 应考虑 due to production process conditions comparison 苛刻, can can is high temperature, low temperature, high speed and other 情况, from can can additives separation understanding, 挥发而失效, formulation 失败. therefore, in types or types above additives and material combined use process in, is separation additives can, must make it in powder coating material material in separation dispersion, can different add material and material combined.

due to additives tool has features, can reinforcement powder coating material formed film rear certain property can, or is decrease/reduce coating film 弊病 出现, therefore additives for powder coating material non important. 随 我国 powder coating material industry large and additives product 进一步 development, additives important property will more add obvious, development 空间也 will more is vast.
