Arti dan kegunaannya

4.1 The paint splatter produced by roller application depends on the paint applied and the nature of the paint roller cover used for the application. In order to eliminate the effect of the paint drum cover as a variable, and therefore limit the sputtering induced variable only to the paint under test, the paint drum cover is replaced by a standard roller with a notch to produce sputtering through a mechanical device that simulates a mechanical drum. Paint drum cover.

4.2 Although much of the development to establish this test method has been carried out using latex paint, enough work has been done to demonstrate its suitability for solvent-reducible coatings.

4.3 Tests during the development of this test method have shown that, like other physical properties, the splash characteristics of coatings may change over time. Karena itu, the results of this test are valid only while the test is running.
