Mixing Two (or more) Component Sealants Efficiently
At the World of Concrete trade show, Albion provided live demonstrations showing some of the tricks to the trade. A helpful trick which we want to share is how to keep a pail from rotating when mixing color packs or two component urethane kits.
Using an Albion #381 series Catalyst Mixer and a 1/2" drill insures a good mix. See the photograph, by using a RAG KNOTTED AROUND THE PAIL HANDLE AND STANDING ON IT you stabilize the pail. This is a simple and quite reliable method used by many professionals in the field. It ensures a proper mix and cuts down on mess.
Most material manufacturers want to insure the material is thoroughly mixed, especially when mixing two component urethane material. We have heard customers encouraged to look for dents on the outside of the metal pail caused by the edge of the mixing blade to insure the mix is complete. From a tool manufacturer's perspective, we want you to be careful not to puncture the pail. The edges of the Albion mixing head are rounded to minimize denting and reduce the risk of puncturing the pail. It is more effective to follow the sealant manufacturer's recommendation for mix time - typically 3 to 6 minutes - but read the pail or spec sheet to be sure.
Adhesives are useful for joining thin or dissimilar materials, minimizing weight, and providing a vibration-damping joint. A disadvantage of most adhesives is that most do not form an instantaneous joint, unlike many other joining processes, because the adhesive needs time to cure.
The earliest known date for a simple glue is 200,000 BC and for a compound glue 70,000 BC.APS can package your reactive adhesives, sealants or resins in a variety of package types including A-Pak® flexible burst seal and divider clip pouches, dual cartridges, and Semkit® Packages. We also offer pre-mixed and frozen packaging services. Acrylics, conductives, epoxies, polysulfides, polyurethanes and silicones represent some of the materials we routinely handle.
