Poly Red-2

Description

Poly Red 2 is a high-performance organic electroplating dye specifically developed for coloring metal surfaces during electroplating and anodizing processes. It is widely used to produce bright, uniform, and durable red shades on plated metal components, offering excellent color strength, stability, and reproducibility. This dye is designed to be compatible with various electroplating systems and provides consistent results even under demanding industrial operating conditions. Poly Red 2 exhibits strong affinity toward metal oxide layers, ensuring deep penetration and long-lasting coloration.

Applications

1. Aluminum Anodizing Applications

• The biggest and most important use of Poly Red 2 is in the aluminum anodizing industry.

• Working Mechanism

  During anodizing, a porous aluminum oxide layer is formed on the aluminum surface. The molecules of Poly Red 2 dye deeply penetrate into these microscopic pores. After the sealing process, the dye becomes permanently locked inside the pores.

• Why Poly Red 2 is Preferred

  · Strong affinity with aluminum oxide

  · Deep and uniform pore penetration

  · Excellent color retention after sealing

  · Long-term shade stability

• End Products

  · Aluminum profiles (windows, doors)

  · Mobile phone & laptop bodies

  · Kitchen utensils & cookware

  · Lighting fixtures

  · Nameplates & panels

• Advantages

  · Bright & glossy red finish

  · Fade resistance even in outdoor exposure

  · Consistent shade across large batches

2. Electroplated Metal Components

• Poly Red 2 is extensively used for coloring zinc, nickel, and alloy-plated metal parts.

• Process Involvement

  After electroplating, the metal surface has micro-roughness. Poly Red 2 dye attaches to the metal surface through ionic bonding and physical adsorption.

• Commonly Treated Metals

  · Zinc plated fasteners

  · Nickel plated hardware

  · Decorative alloy coatings

• Applications

  · Screws, bolts, nuts

  · Bathroom fittings

  · Electrical enclosures

  · Decorative metal accessories

• Key Benefits

  · Smooth and streak-free color layer

  · No peeling or flaking

  · Uniform appearance even on complex shapes

3. Automotive Industry Applications

• In the automotive sector, Poly Red 2 is used for both decorative and functional parts.

• Why Automotive Uses This Dye

  · High heat resistance

  · UV stability

  · Oil & chemical resistance

• Used In

  · Interior trim components

  · Logos, emblems & badges

  · Control knobs & switches

  · Engine bay decorative parts

• Result

  · Long-lasting red shade

  · Premium appearance

  · Minimal color fading under sunlight

4. Electrical & Electronics Components

• In the electrical and electronic industries, Poly Red 2 is used for identification and insulation aesthetics.

• Purpose

  · Color coding

  · Component identification
