coating material stability property is effect/influence its property can key/critical factors 之一, especially is material dispersion property. in coating material and use process in, 不受控 絮凝常常 belt/tape negative effect/influence, 例如颜 material drop, gloss decline and viscosity rise high. 而受控絮凝 type dispersant utilizing additives adjustment material pellets poly is, in ensure material stability dispersion meanwhile, decrease/reduce this negative 面效应. this type of technology in coating material industrial in by application, especially in automotive coating material, and in coating and other product in, 发挥 至关 important function.

what is 受控絮凝 type dispersant?

受控絮凝 type dispersant is through additives control material pellets poly is chemical material 质. 传统 絮凝 phenomenon is material pellets poly formed relatively large pellets, this usually 会导致 coating material unstable property. 而受控絮凝则 is in additives function lower, make material pellets formed types 三维网络 structure, 避免 颜 material pellets between 直接接触. this type of structure can in light micro force lower by bad, in has force 时, material pellets maintain stability.

受控絮凝 type dispersion additives as principle

受控絮凝 type dispersant function principle 依赖于 dispersant separation and material pellets between versus function. low molecular weight lubricating wet dispersant usually tool has more 吸附基团, this in different material pellets between formed 桥梁, 进而构建一 similar 絮凝 三维网络 structure. this type of structure can in 不依赖颜 material pellets 直接接触 情况 lower, maintain material stability dispersion.

当施 add force 时, this type of structure by bad, make material pellets heavy new dispersion, from decrease/reduce coating material viscosity. 受控絮凝 type dispersant can has control material pellets stability property and dispersion property, in coating material and use process in, 避免 因颜 material drop or separation belt/tape negative effect/influence.

受控絮凝 流变学 features

受控絮凝 type dispersant coating material system 特殊 流变行 is. coating material in 静止状态 lower performance relatively high viscosity, is material pellets formed 三维网络 structure. add force 时, structure by bad, viscosity reduce; 而当剪切 force remove 时, structure heavy newly built 立, viscosity again increase. through this features, coating material can in use process in maintain stability, 并避免沉 drop, and other phenomenon.

this type of 流变学 features make coating material can in low force lower maintain relatively high viscosity, in high force lower flow property good, improve/increase coating material application property can, especially is in high requirements coating process in, automotive coating material and industrial coating material.

受控絮凝 type dispersant application

受控絮凝 type dispersant in coating material industrial in has application, especially is in need material stability dispersion requirements high gloss coating material system in. 例如, 受控絮凝 type dispersant used for automotive coating material, 封闭底漆 and in coating in. this coating material usually requirements relatively high stability property and relatively low drop property, especially gloss degree. in this application in, 受控絮凝 can has improve/increase material dispersion property, long coating material lifespan, decrease/reduce drop phenomenon.

in addition, 受控絮凝 type dispersant 流变效应 can improvement coating material property or false property flow features. this make coating material in and process in degree 沉积, in coating process in also can achieve slip flow and coating 布.
