Adhesives are formulated from different chemistries depending on their end use and desired performance. The type and amount of resin, curing agent, fillers and additives are selected to optimize bonding to a particular substrate in a particular environment. In a similar way, the mixing technologies utilized in the production of adhesives also vary from one formulation to another. Mixer selection is based on a number of factors but primarily viscosity profile and shear input.
The ideas discussed in this paper are recommendations based on Ross' collective experience as a provider of specialty mixing equipment to the adhesive industries for over 170 years. Mixer testing and simulation trials are recommended to confirm the suitability of a specific mixing strategy.
