MaxMatt-7 Matting Agent for Polyester/Epoxy Powder Coatings

MaxMatt-7 is an economical chemical matting agent based on carboxyl acrylic resin.

It has excellent matting effect, good storage stability, good impact resistance, delicate surface and scratch resistance which have the following characteristics in polyester/epoxy hybrid powder coating system

• Excellent matting performance: minimum gloss 2.5GU@60°
• Matting principle: chemical matting type, matting agent/epoxy (equivalent 833) =
  1:2.0
• Appearance: flat and smooth, high fullness, high blackness, stain resistance, and
  excellent color stability
• Storage stability: Finished Powder has good storage stability
• Impact resistance: ±50KG.cm, excellent delayed impact performance
• Anti-scratch performance: high cross-linking density, higher hardness and
  scratch resistance than traditional chemical matting agents
• Economical: The formula contains more polyester, which has obvious cost
  advantages when the price of polyester is low; compared with the high melting point X68 type, MaxMatt-7 contains a large amount of resin and can carry more
  pigments and fillers without Affect the appearance
• Adjustable gloss: By adjusting the amount of matting agent and corresponding epoxy consumption, the gloss can be adjusted without changing the performance
• Excellent mechanical properties, excellent adhesion, low selectivity to polyester resin
• Good re-extrusion performance, easy to reuse expired powder or waste powder
• Anti-interference: Very little sensitivity to oven temperature, can be baked in batch
  ovens and cold ovens; little interference from X68 matting agents; little pollution to
  high-gloss powder in the same baking tunnel

Recommended powder coating formula based on MaxMatt-7:

• In different formulas, the best mechanical properties can be obtained by appropriately adjusting the amount of epoxy
• Recommended slow curing polyesters, such as DSM P4055 / P5127 / P6060,
  Zhejiang Tiansong 6700, KHUA 1162 / 1164, Anhui Shenjian 5#A, Maple 1067, etc.
• Please adjust the pigment and filler content according to the actual situation.
  Increasing the filler content is beneficial to matting. It is recommended to choose
  matting filler
• The above formula is for reference only. Various properties vary according to the properties of the resin. Please refer to the test data
• Avoid accelerators or catalytic pigments/fillers; they typically raise gloss and may impair leveling.

Typical Properties:

• Appearance: White or light yellow powder
• Epoxy equivalent weight: about 410
  

Application:

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

Storage:

• 12months @27°C, Keep Dry

Safety and Caution:

• General powder coating safety regulations can be adapted for ZEHM products
• Unless otherwise noted, ZEHM products never contain any heavy metal elements, easy-flammable or explosive materials
• Personal Protective Equipment [PPE] are required to prevent the powder from oral or breath adsorption and skin direct contact
• Any contaminated body parts should be suggested to the above formula is for
  reference only. The performance may be varied by resin types. Please refer to
  experimental data
