Mixing Technologies for the Production of Low- to High-Viscosity Adhesives
A number of factors, primarily viscosity and shear input, are considered when selecting the correct mixing technology for an adhesive formulation.
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. Mixer testing and simulation trials are recommended to confirm the suitability of a specific mixing strategy.
