Cortec releases new EcoAir® Mould Release for Powder Injection Moulding

March 31, 2017

Cortec, St Paul, Minnesota, USA, has released its new EcoAir® Mould Release, a dual-function mould lubricant which includes a bio-based corrosion inhibitor. When sprayed onto a mould, the company reports, the new lubricant will form a thin silicone coating, making it easier to release the finished product after moulding.

The new lubricant aims to prevent some of the defects and delays which can be caused by forced demoulding and to prevent corrosion to moulds by forming a bio-based molecular passivating layer to protect the mould surface. As metal injection moulds can be extremely expensive to replace, proper protection is important to extend their lifespan as much as possible.

Cortec’s new lubricant is available in recyclable EcoAir® spray cans, which the company reports dispense the product using a compressed air system as opposed to environmentally damaging CFC or HCFC propellants. The product is reportedly stable up to 200°C (392°F) and safe for 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’.

Cortec has been producing corrosion prevention solutions since its foundation in 1977, and employs approximately 200 staff. The company’s products have received several coating industry awards.
