The Techne Gelation Timers determine the gelation time for polymers, plastics, sealants, adhesives.
Rheological consistency frequency determines the desirability of a product for a particular application. For example, in resins for surface coatings, in paint manufacture, in adhesives. As a result the accurate laboratory determination of gelation time is necessary for the adjustment of manufacturing formulations or control of processing conditions. The mechanical compression test utilized by the Techne Gelation Timer is preferred over other methods, for example, gel swelling test, agitation test, SP1 gel time, because it provides repeatable gelation times consistent with the physical and chemical change in the gelating fluid. The instrument is sensitive to elastic rather than viscous changes in the fluid and as a result provides more consistent and repeatable results.
