Corro-Coat PE (Polyster Powder Coatings)
Polyester powder coatings are based on acid-functional saturated polyester cured by triglycidylisocyanurate (TGIC). No volatile by-products are given off during the curing reaction. The primary characteristic of polyester powder coating is its supreme color and gloss retention on external exposure. Corro-Coat PE flows easily with good edge cover and excellent resistance to mechanical wear. Simultaneously the coating is resistant to color variations normally caused when over-curing
Polyester powder coatings are ideal for use on metallic building components such as aluminum profiles, sections and sheets, agricultural equipment, garden furniture and leisure products, etc. The polyester powder is prominently suitable for use in electrostatic spraying equipment as well as friction charged equipment. Corro-Coat PE can also be successfully applied to other ferrous and non-ferrous bases. Special products are also available for use on porous bases.
Provided surface preparation has been correctly carried out and an adequate coating thickness has been applied, then corrosion prevention in acidic and alkaline environments are good, but resistance against specific solvents is limited and should be advised on this matter.
Although polyesters can be supplied in low gloss qualities, it must be realized that such variations may have reduced mechanical, chemical and weathering resistance.
Corro-Coat is supplied as standard and accelerated curing ("D" quality) versions.
The Corro-Coat PE formulation and particle size distribution results in excellent performance in electrostatic as well as friction charged application equipment.
