  • Best Practices for Henkel Loctite Stycast UV 7993

    *See Terms of Use Below

    1. Application

      LOCTITE STYCAST UV 7993 has been applied successfully using dip, spray, brush, and flow coating equipment.

      Final coating thickness is influenced by board size, part geometry and application method.

      Dip coat operations: A withdrawal rate of 5inches per minute results in a typical coating thickness of 3 mils. Time allowed for coating run-off before cure will also influence final coating thickness. Coating run-off time should be based on appropriate process factors including board size and component density.

      Spray and flow coating operations: Solventless conformal coatings usually require modified operating procedures compared to solvent-based systems such as lower flow rate through the gun, increased atomization pressure to create a fine mist and spray gun location approximately 2 to 3 inches above the assembled board.

      Equipment parameters such as nozzle design, nozzle orientation and number of passes will impact final coating thickness.

    2. Surface Preparation

      Surface preparation of assembled boards prior to applying LOCTITE STYCAST UV 7993 is not required. However, improved adhesion and reliability performance can be achieved when contaminants such as ionics, dust, salts and oils are cleaned from the assembled board.
