Poly Red-1

Description

Poly Red 1 is a high-quality electroplating dye specially developed to impart a bright, clean, and uniform red shade on electroplated metal surfaces. It is widely used in decorative and functional electroplating processes where consistent color tone, good brightness, and long-term stability are essential. This dye is formulated to dissolve easily in electroplating baths and shows excellent compatibility with common plating systems, especially nickel and zinc plating. Poly Red 1 provides strong color strength, ensuring even color distribution across the plated surface without patchiness or streaks. It helps achieve a smooth, glossy, and attractive finish, enhancing the overall appearance of the plated component.

Uses

1. Decorative Electroplating Applications

Poly Red 1 is extensively used in decorative electroplating baths, particularly in nickel and zinc plating systems. When added in controlled concentrations, it provides a smooth, glossy, and evenly distributed red shade on plated components.
The dye dissolves uniformly in the plating solution, allowing consistent color deposition even on complex-shaped metal parts. It helps maintain stable shade control during long production cycles, reducing color variation and ensuring repeatable results.

2. Automotive Components

In the automotive industry, Poly Red 1 is applied to decorative metal parts such as trims, knobs, logos, fasteners, and visible fittings. The red finish enhances aesthetic appeal and brand differentiation, making components visually attractive while maintaining plating quality.
Its uniform deposition properties make it suitable for both small precision parts and larger metal components used in automotive interiors and accessories.

3. Jewellery and Fashion Accessories

Poly Red 1 plays an important role in the electroplating of artificial jewellery, fashion ornaments, watch components, and accessories. It delivers a rich and elegant red tone that enhances the appearance of intricate designs and fine metal detailing.
The dye is especially valued in this sector because it produces consistent coloration without dullness, improving the perceived quality and market value of finished products.

4. Hardware and Industrial Products

In hardware and industrial applications, Poly Red 1 is used for coloring handles, locks, fittings, fasteners, tools, and metal accessories. The red electroplated finish improves visual identification and decorative value, especially for consumer-facing products.
It is also used where color differentiation or product coding is required, without affecting the functional properties of the metal surface.

5. Electrical and Electronic Components

Poly Red 1 is applied in electrical fittings, connectors, terminals, and metal housings for decorative and identification purposes. The red coloration helps in visual distinction and component identification, while maintaining a smooth and uniform plated surface.
