Special powder coatings

A heat reflective coating is a type of paint or surface treatment that is designed to reflect sunlight and reduce the amount of heat absorbed by the coated surface. Heat-reflective coatings are commonly used on roofs, walls, and other building surfaces to improve energy efficiency, reduce cooling costs, and improve indoor comfort.

Infrared (IR) Reflective Technology is designed to reflect a significant portion of the sun’s infrared radiation, reducing heat buildup on coated surfaces. Unlike standard pigments that absorb both visible and infrared light, IR-reflective pigments reflect the infrared portion of sunlight, which accounts for much of the solar heat gain. This technology helps lower surface temperatures—especially in dark colors—reducing thermal stress, improving comfort, and contributing to energy efficiency in buildings.

Architectural coatings with IR reflective properties are ideal for roofs, siding, facades, and metal panels in both residential and commercial applications. By keeping exterior surfaces cooler, these coatings can help lower air conditioning loads, extend the life of building materials, and contribute to green building certifications such as LEED. They are available in a broad color palette, including deep tones, without sacrificing heat-reflective performance—offering architects and designers greater freedom without compromising sustainability goals.

Applications：

IR Reflective Technology is ideal for use in applications where managing surface temperature and improving energy efficiency are critical. It is commonly used in architectural coatings for roofs, facades, and building exteriors to reduce heat absorption and lower cooling costs. In industrial settings, it’s applied to storage tanks, transportation equipment, outdoor enclosures, and metal structures to minimize thermal stress and maintain safer surface temperatures. This technology is especially valuable in hot climates or sun-exposed environments where heat buildup can lead to material degradation, safety concerns, or increased energy consumption.

	**Actual corrosion resistance is jointly determined by the customer’s substrate type, pre-treatment effect, coating type, and coating process, etc.
	To ensure maximum protection, the workpiece must be pre-treated prior to applying Interpon 600. All metal substrates require degreasing. Ferrous metals should be treated with zinc or iron phosphating, silane, or ceramic coating; aluminum is recommended to undergo chromating or chrome-free passivation to improve corrosion resistance.
Application	Interpon 600 can be applied using manual or automatic spray equipment. To ensure coating consistency, automatic spray equipment is recommended. Unsprayed powder can be recycled through an appropriate recovery system.

Features：

Resistant to metal corrosion：

Since it uses a special undercoat material with excellent corrosion resistance, it can be used safely on outdoor metal equipment.

Can also provide thermal insulation：

By adding an insulating layer that prevents the temperature inside the building from escaping, it is possible to achieve both heat insulation and thermal insulation.

Reduces Surface Temperatures – Reflects infrared radiation to keep exterior surfaces significantly cooler.

Enhances Energy Efficiency – Lowers cooling demand and HVAC energy consumption in buildings.

Extends Coating and Substrate Life – Reduces thermal expansion, contraction, and UV degradation over time.

Supports Sustainability Goals – Helps contribute to green building certifications like LEED and compliance with cool roof standards.

Compatible with Various Coating Systems – Can be integrated into water-based, solvent-based, and powder coatings.

Low Maintenance – Surfaces stay cooler and resist fading, reducing maintenance needs over time.

Tailored to the substrate：

Infrared (IR) Reflective Heat Reflective Powder coating is the ideal choice for steel and aluminum substrates. A special component mix significantly increases the reflection of long-wave radiation at the surface, resulting in noticeably cooler surfaces. This helps minimize material warping and heat transfer into the building’s interior, ultimately decreasing the cooling requirements. The product’s performance is precisely matched to the substrate, ensuring optimal reflection via both the coating layer and the underlying material.
