5、.1 The test paint is applied to a black plastic panel bydraw-down.The coated plastic panel is immediately mountedon an essentially vertical surface above a sheet of paper used tocatch any spatter.A specially designed notched spool roller(see 5.1)is rolled through the film following a definedprocedur
6、e,tending to generate spatter.Any spatter falls uponthe spatter catch paper and,after drying,is rated against thepictorial standards.4.Significance and Use4.1 Paint spatter generated by roller application is depen-dent on the properties of both the paint being applied and thepaint roller cover used
7、for the application.To eliminate theinfluence of the paint roller cover as a variable,and thus restrictthe spatter-inducing variable to the paint under test only,thepaint roller cover is replaced by a standard notched spool rollerto generate spatter by a mechanism that simulates that of apaint-apply
8、ing roller cover.4.2 Although most of the development work to establish thistest method was undertaken using latex paints,sufficient workwas also done to show its applicability to solvent-reduciblepaints.4.3 Tests during the development of this test methodshowed that the spattering properties of pai
9、nts,like otherphysical properties,may in time change.Therefore,the resultsof this test are valid only for the time when the test is run.5.Apparatus5.1 Notched Spool Test Roller(Fig.1).4,55.2 Glass Plateat least 230 by 485 mm(9 by 19 in.)by 6mm(0.25 in.)thick.5.3 U-shaped Film Caster,6,5having a 175-
