Cortec unveils water-based coating for metal protection
Cortec has developed VpCI-372 E, a new water-based peelable coating that it claims is easy to apply and remove for temporary protection of metal parts against rust and corrosion.
According to the company, the VpCI-372 E is an extra thick version of a water-based acrylic peelable coating and provides protection in harsh, outdoor, unsheltered applications.
The E version is a high-build/high-viscosity product specially designed to protect metal surfaces such as splines, threads, or machined areas that have dynamic profiles. According to Miltec, it can be applied to metal surfaces by spraying, rolling, brushing, or dipping and is thick enough not to sag or run off the surface when applied.
In one to two hours, the coating is dry to touch. It hardens into a thick covering that protects multi-metals from corrosion and also offers UV resistance.
The coating is also intended to protect freshly machined surfaces against physical abrasion, such as nicks or dents. When the coated metal part reaches its destination, or is needed for use, VpCI-372 E can simply be peeled off and discarded as solid waste, leaving behind a clean and corrosion free surface.
VpCI-372 E has very low levels of VOC according to ASTM D3960 (0.2 lbs/gal [24 g/L]) and is dry to handle in two to three hours. VpCI-372 E can be matched to some custom colours to suit application needs and can be hand-applied to individual parts or used in automatic production line applications.
