Aluminum Finishing
RPM Industries offers powder coating, wet paint, kynar, anodizing clear and 2-Step colors, Aluminum finishing provides additional corrosion resistance, wear resistance and improved visual aesthetics over mill finish aluminum.
Mill finish aluminum is the finish as it exists at the time the aluminum is extruded. Aluminum extrusion with this type of finish often has a dull gray appearance.
Powder coating paints and liquid paints are organic coatings. Proper pre-treating of the aluminum is used to assure inter-coat adhesion between the paint and aluminum is achieved. Base resins such as polyurethane and polyester are most commonly used for architectural applications and are used to increase weatherability. Painting offers an unlimited number of color options, standard and custom color matched. The main difference between Powder coatings Vs Liquid painting is that liquid paint is solvent based and produces VOC’s.
Anodizing aluminum is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of the aluminum which provides increased corrosion and wear resistance. With the introduction of dyes or thin transparent coatings that reflect light many different colors can be achieved. Anodizing can help seal the aluminum surface and prevent galling of threaded components. Anodizing is not affected by sun exposure; it becomes part of the aluminum surface and will not peel off.
