With summer heat pushing energy demand higher across East Asia, Kansai Paint is promoting its recently introduced HEAT SHIELD EX rooftop coating in Japan as a way for industrial and commercial buildings to cut surface temperatures and trim cooling loads. The water-based, high-reflectance paint is marketed for factory roofs, warehouses and logistics centers that are struggling with rising power costs and stricter environmental targets.

What Kansai Paint’s HEAT SHIELD EX is designed to do

HEAT SHIELD EX sits in Kansai Paint’s industrial and architectural coatings portfolio and is formulated as a thermal barrier coating for metal and concrete rooftops, using a high solar reflectance pigment system to reduce heat absorption on sun-exposed surfaces. Kansai describes the product as a waterborne acrylic coating with infrared-reflective pigments that can lower roof surface temperatures compared to uncoated substrates, based on in-house and field testing on industrial buildings in Japan. The official Kansai Paint product information highlights its use on large factory roofs, warehouses and distribution centers.

According to Kansai, the coating is optimized for sheet-metal and galvanized steel roofs that are common on Japanese industrial facilities, with adhesion-promoting primers available where existing aging coatings or corrosion are present. The company says that by raising visible and near-infrared reflectance, HEAT SHIELD EX can limit daytime rooftop temperature spikes, which in turn is intended to reduce heat transfer into the building envelope and ease the load on air-conditioning equipment in production areas. While exact savings depend on building design and climate, Kansai frames the product as an energy-efficiency tool that can support corporate decarbonization targets in sectors such as manufacturing and logistics.

The product is supplied in light colors chosen to maximize solar reflectance, and is described as low-odor and low in volatile organic compounds to make application easier on occupied sites. Kansai emphasizes that HEAT SHIELD EX is designed for professional use by painting contractors, specifying that recommended film thickness and recoating intervals should be respected to achieve the stated thermal performance. For building owners, the main pitch is a modest incremental coating cost compared to standard roof paints, potentially offset by lower summer cooling bills over the coating’s service life.

In Japan, HEAT SHIELD EX joins a broader domestic trend toward "heat-shield" and solar-reflective coatings promoted by major paint manufacturers as a response to rising average summer temperatures and higher energy prices. Local regulations and voluntary schemes encourage companies to install energy-saving building materials, and high-reflectance roof paints are now seen as one of several relatively low-disruption retrofit options alongside insulation upgrades and more efficient HVAC equipment. Trade publications in Japan have noted that industrial customers in particular are testing reflective coatings on pilot roofs before rolling them out across entire portfolios, reviewing both comfort improvements and power consumption data. A report in Nikkei on heat-shield coating uptake points to demand from factories seeking to moderate indoor temperatures.

HEAT SHIELD EX also fits into Kansai Paint’s sustainability messaging, as the group outlines its targets for reducing greenhouse gas emissions across operations and the product use phase. In recent integrated reports, Kansai has highlighted energy-saving coatings for buildings and infrastructure as one pillar of its strategy, alongside low-VOC formulations and durability improvements that extend repainting cycles. The company frames heat-shield roof coatings as contributing indirectly to Scope 3 emission reductions at customer sites by lowering energy consumption for cooling during peak summer months. In its integrated report, Kansai Paint identifies functional coatings that save energy as a growth focus in architectural and industrial markets.

Within Kansai Paint’s broader product lineup, HEAT SHIELD EX is a niche but strategically relevant industrial coating aimed at building-related energy savings rather than decorative finishes. The company generates a significant share of revenue from architectural and industrial coatings across Japan and Asia, and products like HEAT SHIELD EX allow it to sell higher-value solutions into existing customer relationships with plant operators and construction contractors. Shares of Kansai Paint (ISIN JP3271400008) closed on the Tokyo Stock Exchange at JPY 2,574 on 06/13/2026.
