High Heat Resistant Oil Rubbed Bronze Powder Coating

Surface Finish Options Overview

HIGH HEAT RESISTANT OIL RUBBED BRONZE - Matte Finish - 1,100°F Temp Rating

A high temperature resistant dark bronze metallic with a slight textured finish. Excellent UV & chemical resistance for exterior or interior applications.

*** High Heat-Resistant Powder Coatings are silicone-based and must stay below 90°F in powder form. Monitor your tracking to ensure your package does not sit at a hub or hot mailbox, which can ruin the powder. If your powder was exposed to a higher temperature during transit and started to cure you can do the following - sift the High Temperature/Heat Resistant coating through a flour sifter; discard any pieces that won't break down. Powder that passes through the sifter is is good to use.

Will withstand temperatures up to - 1,250°F and sustain constant temperatures at 1,100°FHigh Heat Resistant (High Temperature Rated) powders are ideal for BBQ’s, industrial heaters, chimney stacks, engine casings, engine manifolds, mufflers, light fixtures, or any application where you require a higher operating temperature

DESCRIPTIONA true high-temperature silicone system using a deep rich carbon black pigment, a slight mini texture finish, and a 15% gloss rating.Developed from a proprietary blend of resins and pigments to provide exceptional service up to 1200°F (649°C).Designed with a universal fine textured finish to hide imperfections & weld marks, making this an all-around resilient coating for multiple applications.

FAQ

1. What is Powder Coating?

Powder coating is a dry finishing process used to apply a protective and decorative coating on metal or other surfaces. Instead of using liquid paint, fine powder particles (usually made of polyester, epoxy, or hybrid resins) are electrostatically charged and sprayed onto a conductive surface. The coated object is then baked in an oven, where the powder melts, flows, and cures into a smooth, durable finish.

Key features:

Durable, hard finish

Resistant to scratches, corrosion, and UV

Environmentally friendly (no VOCs)

2. Benefits of Powder Coating

Powder coating offers several advantages over traditional liquid painting:

Durability: Resistant to chipping, scratching, fading, and wear.

Corrosion Protection: Provides excellent protection against rust and chemicals.

Environmentally Friendly: No volatile organic compounds (VOCs) and minimal waste.

Efficiency: Overspray can be collected and reused, up to 99% material utilization.

Uniform Finish: Smooth, even coating without runs or drips.

Cost-Effective: Single-coat systems can achieve high film thickness, reducing labor and energy.

Aesthetic Variety: Wide range of colors, textures, and effects.

3. What Temperature to Cure Powder Coating

The curing temperature depends on the type of powder used:

Epoxy powder: ~160–200°C (320–392°F)

Polyester powder: ~180–210°C (356–410°F)

Hybrid (Epoxy-Polyester) powder: ~180–200°C (356–392°F)

Typical curing time: 10–20 minutes depending on thickness and oven type.

Always follow the powder manufacturer’s specifications for best results.

4. Process for Powder Coating

The powder coating process usually follows these steps:

Surface Preparation:

Clean the surface thoroughly (remove oil, grease, rust, or dirt)

Methods: chemical cleaning, sandblasting, or phosphating

Pre-Treatment:

Apply a conversion coating or primer if needed to improve adhesion

Powder Application:

Spray the powder using an electrostatic spray gun or fluidized bed

Curing:

Bake the coated object in an oven at the recommended temperature for the powder type

The powder melts and forms a continuous, smooth film

Cooling & Inspection:

Let the coated item cool

Inspect for defects, uniform coverage, and desired thickness

5. How to Spray Powder Coat

Equipment Needed:

Electrostatic spray gun

Compressed air supply

Powder feed hopper or container

Grounding of the object

Steps:

Ground the object: Ensures the charged powder is attracted to the surface.

Spray evenly: Hold the gun 6–12 inches from the surface, moving in smooth, overlapping strokes.

Apply sufficient powder: Ensure full coverage without excessive buildup.

Cure immediately: Transfer the sprayed item to the curing oven to fuse the powder into a solid coating.

Tips:

Maintain consistent speed and distance while spraying.

Use proper ventilation to reduce airborne powder accumulation.

Test a small area to check film thickness and color before full application.
