Description Description The BYK-Gardner Circular Drying-Time Recorder consists of a synchronous motor, mounted in a metal case on rubber-shod tripod, with its shaft positioned in the true vertical. A pivotable arm assembly is attached to this shaft and operates a counterpoised stylus, vertical stylus, consisting of a thermosetting Teflon sphere that does not stick to the drying film.
General Information General Information This instrument measures the air-drying characteristics of paints, varnishes, enamels, drying oils, lacquers, shellacs, adhesives and various other types of coatings and films applied to many types of plane surfaces. The various stages of drying and curing that occur in films are very difficult to define and evaluate satisfactorily in a quantitative manner.
Operation Operation: After running several tests on known materials under controlled conditions, the operator can very easily correlate results obtained with the Circular Recorder and by the finger-touch method for determining the following stages of drying: 1. Set-to-touch: During the first stage of drying, the film is mobile and partially flows back into the scribed channel. The film may be considered „setto-touch“ when it no longer flows back and the stylus begins to leave a clear channel. 2.
Operation and the corresponding graduations on the rim of the circle to be located with great precision. 4. Portability: Compact in design, the Circular Recorder is 4“ in diameter and 4½ high, and weighs about 1½ pounds. It can be operated on a laboratory bench, in a small environmental chamber, or in an oven at a temperature of up to 170°F. 5. Easy Maintenance: There is nothing to clean except the stylus.
Operation just exceed the total drying time; therefore, a choice of motor speeds is available. The 1,, 6, 12 and 24 hour limits of the recorders fit the maximum drying times of most coating applications.
