Cortec's BioPad, Patent Pending, is a unique flexible corrosion inhibiting device constructed from 100% biobased non-woven material, containing 66% biobased content. BioPad ® ® provides an eco-friendly sustainable packaging option for corrosion inhibition and has been awarded USDA BioPreferred SM designation. It is specially designed with Vapor phase Corrosion Inhibitors (VpCI ®) impregnated throughout the substrate.
This powerful USDA certified biobased product provides up to two times as much corrosion inhibiting action as conventional VCI foams. In addition to being biobased, BioPad
® contains a high concentration of VpCI ® in combination with its thin design, resulting in material reduction by up to 94% in comparison to similar polyurethane foam emitting devices.
Cortec's BioPad® provides multi-metal VpCI® protection and desiccant action in one simple step to protect metal parts such as automatic transmission components packaged in reusable plastic boxes.
® is cost effective, adaptable, and easily applied. Simply placing the correct size BioPad ® into your package will allow metal items to be protected while leaving them ready for use; no degreasing or coating removal is required, just remove the item from package and put to use.
The product is excellent for protection of ferrous and non-ferrous metals as well as alloys such as: galvanized and carbon steels, copper, brass, aluminum, zinc, solder, silver, etc. The product is free of nitrites and amines contains no isocyanates.
® conforms to NACE Standard TM0-2008 and RP0487-2000, MIL-I-22110C and has been tested by a certified laboratory in accordance with ASTM D-1748 (Humidity Test) and ASTM D 1735 with excellent results. The product is also RoHS compliant.
The customer, a manufacturer of engines, submitted various packages of camshafts for accelerated corrosion testing. The customer was looking for a rust preventative method that is easy to apply and provides the ability for regular inspection of the parts.The parts were packed in the film containing a strip of BioPad. The parts packed in the plain film were used as a control. All packages were subjected to ASTM D-1748 Humidity chamber test. (50C, 99% relative humidity) for 8 days (192 hours). After the test, control showed significant corrosion. Parts protected by BioPad strip were corrosion free.
