Dispensing two-part adhesives can be a challenge, particularly if the mix ratio is wide or the two components have different viscosities. For a good bond and maximum adhesive performance, the resin and hardener must be precisely metered and thoroughly mixed. But, new dispensing technology makes it easier than ever to dispense acrylics, epoxies, silicones, urethanes and other two-part materials.
Those adhesives have a number of performance properties often not available in single-component alternatives. They provide better storage stability, faster handling and shorter curing times. The disadvantage is a more complex process due to the dispensing parameters required for different mixing ratios and the selection of a suitable static mixer.
