NVOC moisture cure conformal coating now comes in high viscosity, gel and aerosol versions. High viscosity is for thicker coating or manual application (brush, dip and selective spray). Gel is a single part, thixotropic material designed for glob-top applications where the coating should not flow once applied. Cures at room or elevated temperatures upon exposure to atmospheric moisture and incorporates a UV trace to aid inspection. Aerosol uses standard NVOC coating for manual application. Are based on polyurethane technology and are VOC-free.

Fifth Axis Tilt (0 to 30 degrees) together with Four Position Rotate (0, 90, 180 and 270 degrees), are said to provide Film Coater applicators greater flexibility and increased access while conformal coating a printed circuit board. Tilt and rotate accessory is for coating vertical surfaces and underneath components. It enhances access to tight or hard-to-reach areas that may not be achievable with the standard downward approach (0 degrees). While the nozzle is tilted to 30 degrees, the mechanism can be rotated in 90-degree increments to direct the fan pattern to the left, right, front or back to coat all four sides of a component. Uses dual pneumatic motors for smooth, fast and quiet rotate action. Single action rotate speed is variable using flow controls. Is compatible with Select Coat SL-940E platform configured with Film Coater Applicators (SC-104/SC-105 or SC-204/SC-205).
