Mild-Matte A16 Low Temperature Matting Agent for Polyester/TGIC Powder

Mild-Matte A16 is a low-temperature matting agent specially designed for polyester/TGIC powder coating systems.

This matting agent is used with conventional outdoor polyester cuing at low-temperature. Specific features include:

• Matting performance: Lowest gloss of 16GU @60° (Dosage: 6.0% in total)
  
• Curing schedule: Cured at 160℃/15-20min with general-purpose outdoor polyester
  
• Powdering process: pre-mix, extrude and ground with other raw materials; no dry
  blending requirement.
  
• Surface quality: the surface is delicate and smoother than that of dry blending method.
  
• An excess of TGIC must be used, the ratio of matting agent to TGIC is about 8:1
  
• Mechanical properties: Impact strength can pass reverse 50 Kg*cm
  
• Color stability: excellent yellowing resistance after baking.
  
• Matting stability: stable gloss, insensitive to extrusion process, good reproducibility.
  
• Other ： Slow-curing polyester recommended. The curing temperature needs to be guaranteed in order to obtain good mechanical properties and matting
  properties.

Recommended powder coating formula based on Mild-Matte A16：

• Above formulas were illustrated only for reference. Please do trial first before batch
  order.
  
• Please adjust the content of pigment and filler according to the actual situation.
  Organic pigments may speed up the reactions and lead to increased gloss.
  
• Slow curing polyesters are recommended, such as: DSM P4900, 4600, Anhui Shenjian 4#ET, 4868, Tiansong 2701, KHUA GH-2205, GH-2201; Maple FL-2011, FL-2016, FL-2006, Guangzhou Kinte NH-3307, NH-3309, NH-3308, Sino-French 9339, etc. Other not listed polyesters do not mean that the matting effect is not good
  
• Avoid accelerators or catalytic pigments/fillers; they typically raise gloss and may impair leveling
