MaxMatt-8 Matting Agent for Polyester/Epoxy Powder Coatings

MaxMatt-8 is an economical chemical matting agent based on carboxyl acrylic resin. It has
excellent matting effect, good storage stability, good impact resistance, high surface
hardness and scratch resistance.

MaxMatt-8 has the following characteristics in polyester/epoxy hybrid powder coating
system.

• Excellent matting performance: minimum gloss 3GU@60°
• Matting principle: chemical matting type, matting agent/epoxy (equivalent 833) = 1:2.5
• Appearance: flat and smooth, high fullness, high blackness, stain resistance, and
  excellent color stability
• Storage stability: the gel time is 2’00”-3’00”, and storage stability of the finished powder is very good
• 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-8 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
• Low selectivity for polyester resin, especially suitable for 6:4 polyester matting formulation
• 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-8:

• 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 fillers
• 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: ≈ 330

Application:

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
