The production of high-quality repeatable wax patterns is critical to the investment casting process and the use of specialist mould release and washing agents is common practice within the industry and a key component in the chain.

The presentation reviews the chemistry behind what optimal mould release and pattern washing processes endeavour to achieve and provides case studies of the various options and permutations. The paper will review the different categories of mould release agents available and the benefits and usage of TRISOL wax pattern washing agent.
