Leslie, Michigan -- Huron Technologies Inc. has launched two new mould release coatings for the PU sector.
Release Coating 7972 for use with high-resilience flexible foams is a solvent-based type that Huron claims delivers "effective evaporation in moulding conditions with short process times before foam pour, due to a special blend of hydrocarbon naphtha."
Benefits of 7972 include:
• Excellent surface appearance - cutting scrap and increasing profitability;
• Exceptional release - requiring less demoulding time;
• Minimal build up - extending time moulds remain on the production line producing parts
Potential outlets include automotive headrests, armrests, and other typical flexible foam applications.
Another new product from Huron is Release Coating 7882 for flexible foam applications such as tractor and off-road vehicle seating. The supplier says this new water-based release agent "was specifically formulated for MDI (methylene diphenyl diisocyanate) seating foam.
The coating leaves less build-up, extending the time between mould cleanings and
lengthening the time moulds remain in production. The residue left by 7882 is
easier to clean from moulds when cleaning is required, and does not require extra strength
The agent also provides "exceptional slip and ease of release from mould cavities," said Huron. This
ability to deliver a smooth release and prevent poor surface quality in moulded polyurethane parts, reduces scrap, and requires less time for demoulding.
