International. DSM Resins developed a coating under the concept of "Energy Saving", which increases reactivity in two-component clearcoats for repainting.
Normally, reactivity is increased by adding more catalyst to the two-component system. This has many disadvantages, such as a lower pot life (in two-component reaction adhesives or varnishes, it is known as the time that the mixture lasts once made and during which it is still usable maintaining all its properties), and failures in appearance and adhesion.
The company claims that under the concept of "Energy Saving", it developed a resin for the two-component topcoats for repainting without the disadvantages mentioned above.
"When a car painter uses a paint based on this resin, the curing temperature can be reduced from 60 to 40°C without compromising the properties. This resin can be used in other markets that use 2K polyurethane coatings under controlled application conditions, such as agriculture, or construction, commercial vehicles (trucks and buses) or industry in general," the company says in an official statement.
This product was presented during the European Coatings Show that ran until March 21 in Nuremberg, Germany.
