Highly chemical resistant powder coatings

Product details

Product description

MT-EC 1301 is a series of high-performance polyurethane powder coatings formulated in order to provide excellent anti-graffiti properties with good aesthetic appearance.

MT-EC 1301 is suitable for outdoor applications and is available in a range of colors. This series has been developed to meet the main product specifications required defined in the markets such as railways, subways and urban furniture where anti-graffiti performance plays a crucial role.

MT-EC 1301 formulation utilizes moderate emission Polyurethane technology during process.

MT-EC 1301 is available in smooth finishes with gloss level from satin (50GU) up to high gloss (100 GU).

Pre-treatment

Iron phosphate and particularly Zinc phosphating of ferrous metals improves corrosion resistance. Aluminium substrates may require a chromate conversion coating. Aluminium, steel or Zintec surfaces to be coated must be clean and free from grease.

Application

Unused powder can be reclaimed using suitable equipment and recycled through the coating system. Re-coat (overcoating) is not recommended. Powders can be applied by manual or automatic electrostatic spray equipment.
