Huron Technologies Inc. (Leslie, Mich.) has developed Release Coating 7405, a new water-based mold release formulated for polyurethane applications that require a low-gloss surface finish. The manufacturer says the release is particularly well suited for the manufacture of automotive interior components, including armrests, instrument panels and door side panels. According to the company, the release agent has passed standardized paint adhesion tests, specifically the GM 4350 certification performed by external testing services. Gloss readings, using a 60° angle gloss meter, range from 1.0 to 1.2 on black interior components. Additional benefits include minimal buildup between mold-cleaning cycles, a “dry surface feel” on finished parts and minimal scuff-and-mar surface characteristics.
