Product Description

 

Product Description

174/171 are high and low acid value polyester resins, respectively. Used for polyester/TGIC cured powder coating system. Outdoor semi gloss powder coatings can be manufactured by dry mixing powder made from 174/171, which have low gloss, good mechanical properties, leveling and economy.

Polyester powder coating is a themosetting powder coating composed of polyester resin, curing agent, pigment, filler, and additives. In themosetting powder coatings, polyester powder coatings are one of the main varieties of weather resistant powder coatings. In order to distinguish it from polyester epoxy powder coatings, it is commonly referred to as pure polyester powder coatings.

Polyester powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of solvent-free, pollution-free, recyclable, environmentally friendly, energy-saving and resource saving, reducing labor intensity, and high mechanical strength of coating.

Powder coatings are mainly used in functional coating industries such as building materials, furniture, and automobiles. The series of advantages of powder coatings make them have broad application prospects.

Product Features
1. Dual acid value synergistic technology
174 (high acid value)+171 (low acid value) dry mixing: precise control of crosslinking density, reducing gloss while maintaining mechanical strength.
Weather resistance: UV resistant, yellowing resistant (passed 2000 hour QUV test), suitable for harsh outdoor environments.

2. Performance advantages
Flatness: melt viscosity matching, smooth surface after spraying, no sagging/orange peel (Ra ≤ 0.5 μ m).
Economy: Low acid value resin reduces TGIC usage and lowers costs by 15% -20%.
Fast curing: 180 ºC for 10 minutes, suitable for high-speed production line requirements.

3. Environmental protection and safety
Zero VOC emissions: compliant with RoHS/REACH standards, with no heavy metal additives.
TGIC low toxicity formula: certified by SGS for safe transportation and storage.
 

Applications

 

Outdoor Furniture: The system is ideal for coating outdoor furniture, where a balance of flexibility, weather resistance, and impact durability is necessary to withstand varying environmental conditions.

 

Metal Fencing and Railings: Used in the coating of metal fencing and railings, where both corrosion resistance and a smooth, attractive finish are essential for longevity and visual appeal.

 

STORAGE CONDITION

• Storage temperature ≤ 30ºC;
• Storage condition is required to be dry and with good air circulation.
• Avoiding sunlight exposure.

PACKAGE

The products are packed by polyethylene bag, 25kg/bag, 1ton/pallet.
