"HECOTOP®" - UV CURTAIN COATER FINISHES FOR FLAT SURFACES WITH ALMOST "ZERO" EMISSIONS.

January 2002 - ILVA Polimeri research has developed HECOTOP®, a new line of curtain coat UV matte transparent with almost "zero" emissions and solid content higher than 98.8%.

The HECOTOP® range of products has drastically reduce VOC emissions (volatile organic substances) due to their extremely high solid content.

HECOTOP® has helped create a healthier working environment by reducing emissions.

Product stability allows the operator to eliminate product adjustment through the workday. The extremely high solid content allows for excellent filling with the ability to hide defects in surface preparation.
