Metal Finishing

Maglin has developed a superior metal finishing system utilizing e-coating and powdercoating to ensure optimal surface adherence, superior corrosion protection and vibrant colors with high-UV resistance.

Electrocoat (E-coat)

The twelve-stage immersion electrocoat process from Maglin, provides primary corrosion prevention for steel components and superior adhesion of powdercoating to recessed areas and edges.

E-coating leverages an electrical charge to apply a uniform protective coating to metal fabricated products. Developed originally for the automotive industry, e-coating provides superior coverage, adhesion and corrosion resistance for metal parts and surfaces.

• The principle of e-coat is that materials with opposite electrical charges attract. The e-coat system applies a DC charge to metal parts immersed in a bath consisting of 80-90% deionized water and 10-20% paint solids.
• The electric current attracts the solids, coating all surfaces and joints. Once the coating reaches 0.65-0.85 mil film thickness it insulates the components, reducing the coating application until there is a uniform layer of protection. Resin in the paint solids assist adhesion while providing corrosion protection, durability and toughness. As the parts exit the bath, they are rinsed to maintain efficiency and aesthetic design.
• The e-coating is baked onto the surface of the steel for fusion bonding followed by heat curing to form a hard, durable film. The bake oven crosslinks and cures paint film to assure maximum performance properties and superior corrosion protection.

Maglin e-coat uses lead-free paint and chrome-free sealers in a closed system, significantly reducing hazardous emissions. E-coating contains minimal VOCs (Volatile Organic Compounds), very low HAPs (Hazardous Air Pollutants) and produces minimal solid waste.

The electrocoat process can be divided into these four distinct zones:

Powdercoat

Powdercoating applied too thinly erodes quickly and when applied too thick, it causes cracking and peeling. Maglin powdercoat is applied in accordance with manufacturer specifications to obtain optimal thickness to maximize surface protection from abrasive, chemical and climatic conditions.

The Maglin powdercoat process involves multiple steps, including cleaners; rinses; electrostatic powder application; and oven baking to ensure optimal surface adherence and protection. All Maglin colors are designed specifically for outdoor use with high UV resistance and protection from impact and corrosion.
