RoHS Compliant Coatings
|
Because of the continuing restrictions of hexavalent chromium, Bulk Chemicals Inc. has developed new technologies specifically for the
electronics market. BCI can now offer companies who are producing “yellow?#65533; and “clear?#65533; chromate coatings on aluminum, the opportunity to replace the hex chrome with a chrome-free or trivalent chrome product on 5000 series,
unpainted or painted, aluminum.
The European Union has mandated directives, such as the RoHS directive, that enforces the elimination of
hexavalent chromium on aluminum cabinetry used in the electronics or main-frame computer industry. Companies such as Lucent, Nortel, IBM, Ericsson, Motorola, Cisco, and others, must eliminate hex chrome from their units.
Our technology will provide the salt spray and resistivity requirements that is demanded to pass these specifications. Additionally, we can provide both clear and yellow coatings without the use of
hexavalent chromium.
In order to achieve these requirements, BCI has developed a "Process" that includes our E-CLPS® 4600 and E-CLPS® 2100 patented products. The process includes a series of steps that culminate with our E-CLPS® technology. This process can vary depending on customer’s specifications and process
conditions. In the Coil Industry, we offer E-CLPS® 2950SI
and E-CLPS® 2960C for all substrates of painted metal.
We also offer the TRI-CLPS® 6500, our ROHS Compliant
passivation for galvanized steel.
The E-CLPS® process will provide a minimum of 168 hours of salt spray with no pits or corrosion on bare 5000 series aluminum, and, most importantly, provide low surface resistivity that meets the market specification.
Currently our process is approved by Sanmina-SCI and is being used by Ericsson in Sweden.
