Usage Instructions

Surface to be coated should be thoroughly cleaned with a solvent such as Flux Remover G3® (1631). Surface must be completely dry before application of coating. Shake can well. Hold the board to be coated in a horizontal position and spray from top to bottom, holding the can four to six inches from surface. First, apply a light topical coating, then, after board has been fully coated, immediately apply a second heavier coat. Allow material to flow around the components. After application, invert can and spray until no liquid is expelled. Coating will be tack free in approximately 15 minutes; however, full cure requires 24 hours depending upon humidity. Complete removal can be achieved in 30 to 45 minutes by using the (2510) Conformal Coating Remover. Removal time depends upon temperature, thickness of coating and application.

Thinning/ Removal

Techspray coatings can be thinned to meet production requirements using Conformal Coating Thinner (2105). Conformal Coating Remover (2510) is also available for rework and repair, although coating is often just burnt through in the soldering process for spot repairs.
