Chemical Conversion Coating for Aluminum

Protocase is pleased to offer in-house Chemical Conversion Coating for Aluminum.

What is it?

Chemical Conversion Coating is often referred to as chem film, chromate coating, or yellow chromate coating. This coating process applies chromate to the metal substrate, creating a surface that is corrosion resistant, durable, and exhibits stable electrical conductivity.

Chemical Conversion Coating is used to protect enclosures and metal parts from corrosion, and to ensure that reliable electrical connections can be made to aluminum chassis and components. It is also an effective pretreatment for powdercoat. Protocase’s Chemical Conversion Coating process meets a number of specifications, and qualifies as Type II, Class 1a and 3 under MIL-DTL-5541F. In simple terms, ‘Type II’ means the process does not utilize toxic and dangerous hexavalent chrome. Class 1a refers its ability to protect against corrosion. Class 3 refers to its ability to provide reliable electrical conductivity. Details are given below.

What do we coat?

Protocase will process a) sheet metal parts that have been fabricated in our own facility, or b) parts that have been fabricated or machined elsewhere. Applicable metals are listed above.

Lead Times:

With Protocase-fabricated parts, because the coating is done in-house, chemical conversion coating can be applied to enclosures and parts within 1 day. This means we can offer fully fabricated and finished sheet metal enclosures and components with chemical conversion coating, in as little as 3-4 days. Customer-supplied parts Protocase can apply chemical conversion coating to customer-supplied parts in as little as 3-4 days after receipt of parts.

Details:

Protocase uses CHEMEON TCP-NP®, which meets the most widely used military specifications for chromate conversion applications, including MIL-DTL-5541F Type II, Class 1A and 3, as well as MIL-DTL-81706B. The coating subtly changes the appearance of the surface, which exhibits nearly clear iridescence, with a subtle gold to violet tint.

CHEMEON TCP-NP® is an environmentally friendly trivalent chromium formulation, free of toxic and dangerous hexavalent chromium. CHEMEON TCP-NP® conforms to a wide variety of environmental and workplace safety regulations, such as RoHS, WEEE, ELV, REACH and the OSHA PEL.
