D4707-24 – Standard Test Method Technical Guide
🎯 Overview and Significance
This test method, designated ASTM D4707-24, standardizes the evaluation of a paint’s tendency to spatter during roller application. The core principle involves isolating the paint’s properties by replacing a conventional paint roller cover with a standard notched spool test roller. This substitution eliminates the roller cover’s material, nap, and condition as variables, restricting the spatter-inducing variable strictly to the paint under test.
Applicability Note: Although this method was primarily established using latex paints, its applicability has been successfully demonstrated for solvent-reducible paints. It is critical to recognize that the spattering properties of paints may change over time; results are strictly valid only for the time when the specific test is conducted.
⚙️ Required Apparatus and Materials
Precise dimensions are defined for the test apparatus to ensure reproducibility. The procedure requires a rigid glass plate, a U-shaped film caster with a precise clearance, black plastic panels, and a metronome to standardize the rolling speed.
