Abstract

A properly designed and formulated lipolytic enzyme additive into laminates provides a self-degreasing material that can be prepared using conventional, established production equipment. Laminates were prepared by first infusing a resin formulation into kraft paper and then conditioning the resin in a forced air oven. Manual pressing of samples between aluminum panels was carried out at commercially-acceptable pressures and temperatures. The activity of the enzyme was then determined by following the hydrolysis of the oil-analog p-nitrophenyl acetate using a colorimetric method. Initial results indicated that the enzyme retained complete activity in the resin alone up to 105°C for two hours. When properly conditioned, the lipolytic enzyme not only remained catalytically active after being pressed under manufacturing conditions, but also remained stable in pressed composites stored at room temperature.
