Product Overview
Model: MT-062A Yellow powder coating
Epoxy-polyester thermosetting electrostatic spray powder coating is a hybrid material combining epoxy resin and polyester resin, offering superior flowability, decorative properties, mechanical strength, and corrosion resistance. This coating is widely used for indoor metal surface protection in automotive, home appliance, metal furniture, instrumentation, fitness equipment, and radiator industries. Its dual-resin formulation ensures excellent adhesion, impact resistance, and chemical stability, making it a preferred choice for high-performance industrial applications.

Application Fields
This coating is primarily used for indoor metal surface protection, including:
- Automotive components
- Home appliances (e.g., refrigerators, washing machines)
- Metal furniture and office equipment
- Lighting fixtures and HVAC systems
- Instrumentation and fitness equipment
Its adaptability to various curing conditions (standard/low-temperature) enables compatibility with diverse production schedules.
Storage and Transportation
Storage: Maintain below 25°C in ventilated, dry, and clean environments. Avoid direct sunlight, fire sources, and heating equipment. Stable shelf life up to 12 months when stored under recommended conditions.
Transportation: Use air-conditioned vehicles or transport during cooler periods to prevent heat-induced degradation. Avoid exposure to moisture or humidity, which may compromise powder flowability and electrostatic properties.
