Chem-Trend (Howell, MI, US) is emphasizing the continued evolution of its Chemlease and Zyvax mold release brands with the development of water-based release systems that perform as well or better than customary solvent-based products. Chem-Trend's water-based release systems are said to provide significant environmental and workplace advantages and boost performance for composite manufacturers. Reported advantages include increased throughput by minimizing mold fouling, improved part cosmetics and reduced part rework. Chem-Trend’s water-based alternatives can be applied by wipe or with spray equipment onto ambient or hot tooling.
