Description
Application Methods:
1. Dissolve the diazo powder in 40-100cc of water and shake well.
2. Pour diazo liquid into emulsion and mix thoroughly. (Note: use only stirrer made of wood, plastic or stainless steel only.)
3. Sensitized emulsion should stand for at least 2 hours (preferably overnight) to allow air bubbles caused by mixing to rise to the surface and break. Eventually this will minimize or eliminate pinholes problem.
4. Apply coating either manually using a scoop coater or with an automatic coater.
5. Thoroughly dry screen in horizontal position, print side down. Temperature should not exceed 105°F (40°C ).
6. Place emulsion side of photo positive in contact with print side of screen. Exposure times for Solcoat DC/ 9500 will vary depending on your set- up, see exposure guidelines for estimated times.
7. Gently spray both sides of screen with water, wait 30 seconds then gently wash print side of the screen. Rinse both sides thoroughly.
8. Dry the stencil thoroughly for 30 minutes or the screen can be exposed to heat, not exceeding 140°F (60°C).
