How To Reproduce a 3D Sculpture Using Brush‑On™ 40 Mold Rubber
Step 2: Dispensing Material
The mix ratio of Brush-On 40 is 1A:1B by volume. For this application, one cup of Part A liquid and one cup of Part B paste is measured out. Be sure to carefully pack the paste into the cup in order to eliminate any air voids. Combine Part A with Part B in a mixing container. Since the original model is white and the mold rubber is white, SO-Strong® Blue Tint is added to this first mix of rubber to help ensure thorough coverage over the model. It also helps by acting as a positive mix indicator. Mix Parts A and B thoroughly until all color streaks are eliminated, an indicator that the rubber has been properly mixed.
