Arkema resin to keep roofs cool

FRANCE: Arkema has signed an exclusive agreement to supply its Kynar Aquatec PVDF resin to Cool Roof France, a specialist in reflective coating for roofs. 

Cool Roof is the European leader in white paint solutions for the roofs and facades of industrial and commercial buildings, which reflect solar radiation and thus make it possible to protect waterproofing membranes while considerably reducing air conditioning costs during periods of extreme heat.

Arkema’s Kynar Aquatec PVDF resin will be used used in the topcoat and provides lasting protection for the whiteness and reflectivity of paints for up to 20 years.

This license will grant Cool Roof the exclusive right to promote and use formulations with Kynar Aquatec resin on its sites in France and main European countries as well as on the Ivory Coast, Senegal, in Morocco and Tunisia. 

Painting roofs white is a common practice to remedy the absorption of solar radiation for areas with strong sunlight. But conventional paints rarely resist beyond 5 years, losing their reflectivity with the appearance of dirt and micro-fungi and the intensity of UV rays damage them, making them porous.

Roof instrumentation repainted in white and protected by a topcoat based on Kynar Aquatec is said to have reduced building air conditioning energy costs by 15% to 30%.
