Test for Coating Shrinkage
Shrinkage is a concern to paint and dental adhesive manufacturers among others. Coatings should adhere to the applied substrate uniformly. This test determines the shrinkage among various coatings and serves as a comparison of different substrates on which the coatings are applied.
Applicable science concepts:
Scientific measurement. Scientific method.
Manufacturer's instructions should be followed and eye, hand , and body protection is required.
Results of individual class groups can be arranged and statistical analysis performed. Our test results showed none to over 2 mm shrinkage among the various paints, epoxies, and waxes tested.
The results of this test should be correlated with other tests to determine the optimum coating for a given application. Also the physical and chemical parameters should be explored and correlated with each other for a given application.
