6、ler Spatter43.Summary of Test Method3.1 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
7、 the film following a definedprocedure,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 ap
8、plied and thepaint roller cover used 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 mechanis
