Goniometer in Circle-Prosco Lab
A new non-chrome coating with outstanding paint adhesion properties. We achieved over 3000 hours in NSS on painted aluminum panels with 2-3 mils of polyester-urethane paint. Useful on parts to which a sealer is applied to improve hydrophilicity or corrosion resistance.
A two to four stage process that provides excellent corrosion resistance and paint adhesion. Useful on parts which will be painted or to which a sealer is applied to improve hydrophilicity or corrosion resistance.
An additional coating step after the conversion coating provides enhanced corrosion resistance and excellent hydrophilicity. Subsequent painting operations can be enhanced or eliminated.

An additional coating step after the conversion coating provides enhanced corrosion resistance and excellent hydrophilicity.
A one stage process that imparts good corrosion resistance to parts. The hydrophilicity of the aluminum surface is also improved.
After manufacturing chromate conversion coatings for two decades, we developed and commercialized the first non-chrome conversion coating - Alcoat® 1000 - for the aluminum heat exchanger industry in 1994. We phased out production of chromate products in 2005 as part of our commitment to the environment and our community. The following products represent the latest in non-chrome technologies.
Our specially engineered coatings are designed to provide increased corrosion protection, biocidal/biostatic properties, or hydrophilic surface properties. As a leader in the field of conversion coatings, Circle-Prosco has years of experience in properly selecting a process to meet the needs of our customers.
CPI Aluminum Coatings pass testing for ASTM B-117 Salt Spray Test, ASTM G-85 Modified Salt Spray (SWAAT) Test and ASTM D-5725 Surface Wettability (Hydrophilicity) Measurement.
