Mild-Matte A-2L Polyester/TGIC Powder Coating Matting Agent

Mild-Matte A-2L is a matting agent for polyester / TGIC powder coating system.

Mild-Matte A-2L is suitable for matting with high resin content. The key features of Mild-Matte A-2L are good surface fullness, stable gloss, and small selectivity to polyester. The matting agent has the following characteristics：

• Matting performance: Lowest gloss of 6-8GU @60° (Resin content 65%, Dosage: 7.5% in total)
  
• One-shot effect ： No dry-blending is required
  
• Surface quality: good surface fullness
  
• Durability：good UV resistance and good weather resistance
  
• Mechanical Properties: (+/-) 50Kg*cm impact (GB/T1732-93)
  
• 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 A-2L:

• Above formulas were illustrated only for reference. Please do trial first before batch order
  
• Mild-Matte A-2L : TGIC ≈ 10~15:1
  
• 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.
  
• Recommended slow curing polyesters, such as DSM P4900 / P4600, Anhui Shenjian 4#E, 4#ET, 4#A, , Zhejiang Tiansong CE2701 / CE2098 , KHUA 2221 , , Maple FL-2016/FL-2011, Guangzhou Kinte NH-3309/NH-3308etc.
