A method and apparatus for dispensing liquid compositions. The apparatus includes a reservoir for containing the liquid at a low temperature, a metering device for transferring the liquid to a circulating loop at a higher temperature, a heater/mixer for coincidentally heating and mixing the liquid in the loop and means for dispensing the liquid from the loop. The invention is particularly useful for dispensing liquid adhesive and coating compositions, including thermosetting polymers, heat sensitive polymers or plastisols and other dispersed liquid systems. In addition, mixtures of polymeric liquids with other components such as gases, solvents or liquid blowing agents may be employed with uniformity of composition for dispensing foams or atomizable paints.
