for/regarding already 经确定 formulation system, according to formulation property and leveling agent property can selection combined leveling agent product types.

acrylic leveling agent usually used for and in formulation in, requirements gas and lubricating wet property, selection in molecular weight or polymer/macromolecule amount acrylic leveling agent. in in, if requirements lubricating wet property more strong/high, can use has machine silicon leveling agent and can significantly reduce surface force modified acrylic leveling agent （如 fluorine modified acrylic leveling agent, acid modified acrylic leveling agent ）, if has machine silicon leveling agent and fluorine modified acrylic leveling agent has stability foam, effect/influence 层间附 force and other function, use acid modified acrylic leveling agent.

in and transparent formulation in, film appearance requirements comparison high, generally selection low molecular weight acrylic leveling agent, can obtain good property can, film easy generate 雾影. in crosslinked solid system in, use reaction property can acrylic leveling agent can obtain relatively good property can, improvement film property can. if requirements film flow property relatively good or light slip property, resistant property relatively good, need use has machine silicon leveling agent, in this type of lower, most good is has machine silicon leveling agent and acrylic leveling agent combined use. need is, has machine silicon leveling agent in provide 垂直施工流平 property can meanwhile, also can has decrease/reduce coating material lower toward. another, in metal light formulation in, use has machine silicon leveling agent, is it can can 导致排列 non-uniform aluminum material sheet/slice 状, film color non-uniform.

powder coating material process separation is stage/phase. stage/phase is powder 粒熔化, stage/phase is powder 粒熔化 rear 流入平整漆 film, powder coating material solvent agent, in formed film process in generate surface force degree, more more is and lubricating wet property has 关.

acrylic type leveling agent used for powder coating material in. leveling agent is liquid 体, 应事先 will its made formed masterbatch rear can use, also has acrylic leveling agent made formed powder 末, used for powder coating material, this category of product will liquid acrylic leveling agent in silicon powder upper, low leveling agent carbon acid 钙. if powder coating material need light slip anti 挂, need use has machine silicon leveling agent. has used for powder coating material has machine silicon leveling agent, use has machine silicon leveling agent attention/notes shrink 孔.

water property coating material system separation is water solvent property system and system. in water solvent property system in, need strong/high reduce system surface force, most commonly used leveling agent is has machine silicon and fluorine carbon material leveling agent function and its in solvent agent type coating material system in application same. 当然, if need true positive light slip surface, water property system acrylic leveling agent is necessary.

for/regarding system, formed film mechanism full different, viscosity solvent agent 挥发而变化. in formulation in add leveling agent can improvement coating material lubricating wet property, acrylic type leveling agent can improvement film degree, through add 入流变 control agent control and adjustment coating material main/primary flow property can.
