MUF resin is widely used as an adhesive in wood industries, coating technology, paper industries and a main material in kitchenware production. In various applications, different resin properties are needed to suit its application. Important resin properties are for example higher resin solubility, low curing period with lower temperature and catalyst amount, good stability for longer shelf life, and lower free )brmaldehyde emission, as formaldehyde is very toxic, and can cause cancer. One of the factors that affecting the MUF resin properties is the mole composition. The mole composition is a ratio of/brmaldehyde to amino compound i.e. melamine or urea, in each reaction stages. Besides that addition of other chemical such as sorbitol, may be added to enhance the resin properties. In Turin (1998)and Gapud et al. (1999) researches, addition of sorbitol has improve the resin stability and solubility in water and also cured resin flexibility. Using experimental design such as Surface Response Method optimises the product formulation. This method is more satisfactory and effective than other methods such as classical one-at-a-time or mathematical methods because it can study many variables simultaneously with a low number of observations, saving time and costs. Hence in this research, statistical experimental design or mixture design is used in this work in order to optimise the MUF resin formulation.
