Polyester Epoxy Coil Coating

PRODUCT SPECIFICATIONS:

1. PRODUCT  DESCRIPTION

  1. Coil coatings have been developed primarily to meet the exterior durability requirements of agricultural, industrial, and preengineered buildings. They are based upon the latest technology in highly durable polyester resin chemistry.

 

  1. Coil coatings deliver an excellent balance of exterior gloss and color retention, good

chalk resistance, forming flexibility, and over-all cost effectiveness.

  1. Coil coatings use only the most highly durable pigments available to obtain long term colorfastness properties unequalled by any polyester coating system in the industry.

 

2. SYSTEM OVVIEW

  1. Coil coatings are designed for one or two-coat application on aluminum and two-coat application on steel substrates. They are formulated using proven, field-tested resin systems to provide the durability required for most agricultural, industrial, and pre-engineered building panel systems. Coil coatings should be applied on properly cleaned and pretreated aluminum and steel substrates, including hot dip galvanized steel, Galvalume, and Zincalume.

 

  1. Recommended primer dry film thickness is a nominal 0. mil over hot dip galvanized and a nominal 0.25 mil over Galvalume and recommended topcoat thickness is a nominal 0.75 mil. Our new durable

Coil coatings technology has the added advantage of better recoatability compared to siliconized polyesters. The coating system can be applied at high line speeds for maximum production efficiency.

3. COMMICAL USES

  1. Beautify and protect roofing and side wall panels as well as general building components for agricultural, industrial and pre-engineered buildings.
  2. Applied to tractor trailers and high end garage and entry door systems. With improved flexibility over siliconized polyester, these coatings are perfect for roll-forming multiple building panel profiles.

 

4. DURABILITY

  1. Coil coatings have been developed to give excellent durability in real life outdoor exposures. The coatings exhibit excellent resistance to the damaging effects of ultraviolet radiation, weather, and humidity. It offer excellent moisture resistant properties and ease of cleanability for long-term building aesthetics.
