Nouryon-roof-coatingNouryon has launched a new solution for the building and construction market that boosts the effectiveness of energy-saving “cool roof” coatings by improving their ability to reflect light and enhancing their self-cleaning properties.

Reflective Cool Roof Coatings with Self-cleaning Properties

The new concept combines Nouryon’s Expancel® expandable thermoplastic microspheres, which reflect light, and its Levasil® colloidal silica, which improves the performance of the coatings.

In addition to temperature reduction, the combination of Expancel® with Levasil® colloidal silica also improves the adherence and mechanical properties of the coating without sacrificing elasticity and flexibility. The new solution also has self-cleaning properties that extends the life of the coating.

Coatings to Reduce Energy Consumption

Use of reflective cool roof coatings is on the rise in warmer climates, where they help to reduce the need for air conditioning and in turn reduce energy consumption. When produced with Nouryon’s Expancel microspheres, cool roof coatings can bring down the external surface temperature of a building by as much as 15 degrees Celsius.

We have already made this offering available in Asia, Europe and Mexico and have achieved great results, receiving nothing but positive feedback from our customers,” says Patrick Wilhelm, VP of colloidal silica at Nouryon.

Nouryon will now offer this technology to customers in the US, teaming up with distributor CoadTech – Cool Additives Technology. CoadTech has experience with both product lines and has a long-standing relationship with Nouryon as a distributor for Expancel.
