Molded products fabricated from various silicones are becoming more popular. The removal of these products from their molds is essentially a peel process. Cyclic peel testing, the loading of a sample at subcritical peel levels, gives a more precise analysis of the adhesion properties of this joint than standard peel testing. A study was conducted using aluminum and silicone molds onto which two castable platinum cured silicone materials were delivered and cured. This technique allows for a simple, precise, and cost effective way of optimizing mold release agents, candidate product materials and curing protocols before the costly and time-consuming step of fabricating complex molds is undertaken. Results will compare data from cyclic peel and standard peel tests.
