[b]Akzo-Nobel's technology for FRP[/b]
[b]Interpon Impress®[b][/b][/b]
Due to its benefits in cost-saving & environment-friendly, Powder Coating for reinforced plastics has been a hot topic. Akzo-Nobel, the technical leader of the world coating, and also the world’s largest supplier in powder coating, has developed a new product traded as Impress.
Impress is the trade name for an in-mold powder coating process used as either a primer or a finish coat for compression molded reinforced plastic substrates including SMC、TMC、BMC & FRP.
[b]Features:[/b]
Fast free radical cure mechanism (no additional cure time in the mold)
High cross-link density (high hardness and chemical resistance)
Internal mold release (no need to spray on mold release agent)
Oxygen inhibited cure (enables chemical co-reaction with substrate)
Impress finish matches mold gloss, texture,
[b]Process[/b]
Apply powder to hot mold, 100-200 microns
Powder fuses, melts, flows, gels, 10-30 secs
Unreacted FRP into mold cavity
As press closes, substrate flows under heat and pressure to fill cavity, < 5 secs
Coating remains intact against mold surface
Substrate and coating co-react, 1-5 minutes
Coating releases as cured part is removed
[b]Benefits [/b]
Product durability and performance
Isolate fibers and pores from the surface
Reduce solvent penetration
Improved weathering possible
Homogeneous surface
Moving value to the surface
Application
Heavy truck components&
Stadium seating
ADA Safety Tile
Racing/motorcycle helmets
Recreational boats & Jet Skis
Sanitaryware & showers
Bus Seats/Railcar seats

玻璃钢表面使用粉末涂料涂装，因其具有环保优越性正受到人们越来越多的欢迎，也成为粉末涂料厂商研发的热点，阿克苏•诺贝尔作为全球涂料技术的领导者，是塑料及复合材料（如：玻璃钢）涂装用粉末涂料的主要供应商。
Interpon Impress 是塑料及复合材料（如：玻璃钢）涂装用粉末涂料，用于模压成型涂装的底漆或面漆。涂装底材主要是表面粗糙（内有孔穴，玻纤等）的TMC、SMC、BMC&RTP，采用模压成型的方法使得表面一次涂装平整。
[b]粉末涂装特征[/b]
 激烈快速的固化机制
 无需太多的模内固化时间
 高交联密度
 高硬度和好的耐化学性能
 内部脱模
 无需喷涂脱模剂
 氧气内嵌固化
 使粉末与底材发生化学反应
 Impress表面状态与模具吻合较好（光泽，纹理等）

粉末涂装步骤：[/b]
将粉末喷涂于预热的模具表面，（100-200 micron）
粉末熔融、流平、胶化 （10-30 秒）
未处理的玻璃钢置于模腔中
随着模具的合闭，底材在热压作用下填满模腔
涂层相对于模具表面保持完整
底材和涂层反应 （1-5分钟）
固化脱模
[b]粉末涂装优点[/b]
产品的性能和耐久性
涂层将玻纤、小孔覆盖
提高耐溶剂性能
改良耐候性
表面平整，光亮
为客户创造价值
