Dual protection via lubrication for easy release and bio-based corrosion inhibitor Spray-on silicone Molecular passivating layer No CFC or HCFC propellants

CORTEC’s new EcoAir® mold release provides dual protection by combining lubrication with a bio-based corrosion inhibitor for injection molds and other metal surfaces. Easy release is an important factor in the molding of metalcastings: Castings that do not easily come out of their molds risk defect and slow down the entire molding process.

Corrosion protection is another important consideration for the molding industry. Metal injection molds are expensive and must be stored under specially regulated temperature and humidity conditions. Therefore, protecting these molds from corrosion can serve an important role in securing the longest possible service life of valuable parts, especially those used in corrosive molding conditions.

When sprayed on the mold, EcoAir mold release leaves a clear, thin non-staining silicone coating that makes it easier to release castings from their molds. The bio-based corrosion inhibitor component forms a molecular passivating layer to guard the mold surface against aggressive species, protecting it from corrosion during operation and storage.

EcoAir mold release is versatile and can be used for a variety of purposes:
•  Easier release of castings
•  Corrosion protection of metal molds
•  Lubrication and corrosion protection of tools, pulleys, guides, motor bearings, and battery terminals
•  Easier disassembly of “frozen” metal parts

Cortec has made application and disposal more environmentally friendly by packaging EcoAir mold release in recyclable EcoAir spray cans. These cans dispense the product through the power of compressed air without the use of CFC or HCFC propellants that might affect the ozone layer. Bag-on-valve technology allows EcoAir mold release to be sprayed in any direction, even upside down. The aluminum can may be recycled when emptied.

EcoAir mold release dries quickly and offers excellent water repellency. It restores dielectric properties and is stable up to 392°F (200°C). EcoAir mold release is safe to use on painted surfaces, rubber, and plastics. It has been tested according to ASTM D 1735 “Standard Practice for Testing Water Resistance of Coatings Using Water Fog Apparatus.”
