 (4) Method of use DML3113 is suitable for conventional spraying, brushing and other processes. In order to get a better paint film, after spraying and brushing, it should be placed in the air for 5 minutes. Use 365nm UV light to ensure that the UV light can fully irradiate the surface of the paint film. Cure rate depends on UV intensity, distance from light source to film, depth of cure, film clarity, and substrate clarity. After use, the remaining materials should be covered immediately and filled with dry air or nitrogen protection, and ensure that the materials are kept away from ultraviolet rays and sunlight. The substrate should be thoroughly cleaned before coating, this is to ensure good adhesion of the conformal paint on the substrate. In addition, all flux residues must be removed to avoid corrosion on the PCB board.
