Polyester Tgic Outdoor Transparent Powder Coating for Wheel Hub

Product Description

Polyester TGIC Clear Powder, Outdoor Transparent Powder Coating for Wheel Hub
Introduction
As a representative of solvent-free coatings, powder coatings, together with water-based coatings, have become the mainstream of the development of the coatings industry in recent years. The research on powder coatings for automotive coating has been carried out for more than 20 years, and the application field was initially limited to auto parts, automotive primers, anti-rock primers, etc. It was not until the late 1990s that it was used in batches for car topcoats and covers glossy paint, becoming a real car coating.
At present, the main powder coatings for aluminum wheels on the market are wheelbase powder and overcoat transparent powder. Overcoat clear powders for automotive applications must have outstanding performance in terms of film thickness, gloss, and brightness. Must have good mechanical properties such as impact resistance, scratch resistance, and excellent adhesion. Coatings must be resistant to acid rain corrosion, temperature fluctuations, and UV rays, while complying with environmental protection and safety requirements, making production more economical while meeting quality goals. The overcoat clear powder is mainly polyester type, GMA acrylic type, etc.
The acrylic-type transparent powder has a good appearance and weather resistance, so most of the current aluminum wheel hub covers use acrylic-type transparent powder. However, the acrylic-type transparent powder has poor coverage on the corners of the aluminum wheel hub due to low viscosity and large flow, resulting in poor corrosion resistance of the aluminum wheel hub. Compared with acrylic-type transparent powder coatings, polyester-type transparent powder coatings have better edge and corner coverage and better corrosion resistance.
Key Features:
Excellent exterior exposure durability
Excellent transparency
Excellent physical properties
Excellent clarity and flowing
Application Field:
Outdoor transparent powder coating series products are based on saturated carboxyl polyester resin and TGIC curing agent as the main base materials, which can be used for thermosetting powder coatings for electrostatic spraying and fluidized bed dipping. It is a series of products specially designed for the characteristics of light coating on the surface of the aluminum wheel hub, and can also be used in the fields of External protective or decorative coatings for metal furniture, metallic and pearlescent effects, mixed colors, etc.
