Murakami 901 Blockout Fluid - Gallon
Murakami BL-901 Red Blockout is a medium viscosity, water soluble red blockout. BL-901 is designed to fill the open areas of the screen that are not covered by emulsion or film. BL-901 can be used for masking other designs on the screen until they are ready to be printed. BL-901 is excellent for touching up pin holes and fish eyes
Step 1:The screen must be dry and free of contaminants. Spread BL-901 evenly with a plastic squeegee on the print side of the screen over the areas to be filled. Remove excess BL-901 from the squeegee side.
Step 2:Touch up all defects, including heavy blobs that tend to gather outside of the filled area. Allow BL-901 to completely dry.
