GMA-600 Matting Acrylic Resin

GMA-600 is epoxy-based solid acrylic resin with epoxy equivalent weight of 600 g/Eq. It
can be used in polyester/TGIC and polyester/HAA systems to prepare powder coatings of outdoor weather-resistant low-gloss powder coatings. Specific features include:

• Matting performance: Lowest gloss of 3 GU @60°
  
• One-shot effect ： No dry-blending is required
  
• Surface quality: good smooth appearance, high fullness, good stain resistance
  
• Mechanical Properties: +50/-30Kg*cm impact (GB/T1732-93)
  
• Good scratch resistance

Recommended powder coating formula based on GMA-600:

• 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.
  
• Recommended slow curing polyesters in TGIC system, such as DSM P4900 / P4600, Allnex CRYLCOAT 2441-2 /2491-2, Anhui Shenjian 4#E, 4#ET, 4#A, Chansieh EL6600, EL6800, Guangzhou Kinte NH-3309/NH-3308 / NH3386, Jsbesd YZ9803, KHUA GH2221, Maple FL-2016/FL-2011, Zhejiang Tiansong CE2701 / CE2098, Zhengjiejituan ZJ9032 / ZJ9033, etc.
  
• Recommended polyester in HAA system: Allnex CRYLCOAT 2618-3, DSM P847 / DSM P865, Guangzhou Kinte NH ‐ 6583, Shen ‐ jian 5405, KHUA GH3301, Etiansong CE3068, Huangshan Zhengjie ZJ9104, Maple FL‐3017A / FL‐3002, etc.
  
• Recommended Low OH Polyester, such as Yinyang YE-2080, DSM P6504, Synthomer Albester 3210 etc.
  
• In actual use, it is found that slow curing polyester is beneficial to matting performance.
  
• Avoid accelerators or catalytic pigments/fillers; they typically raise gloss and may impair leveling.

Application:

• Pre-mix and Co-extrusion [One-Shot Method]
  

Storage:

• Shelf life: at least 12 months @27°C. Keep dry, expired products can be used after passing inspection.
