Dowsil CC-2588 conformal coating protects printed circuit boards and electronic components against high humidity and corrosion.

Silicone-based coating is odorless and offers low VOCs. Cures at room temp., supports spraying for higher throughputs and enables automated inspection equipment to use UV to identify voids in conformal coating. Forms tough, scratch-resistant surface. Once cured, it is reportedly comparable to other resin conformal coatings in terms of toughness. Has durometer of 76 Shore A; offers good mechanical strength. Provides reliable adhesion without delamination associated with acrylate conformal coatings and darkening associated with polyurethane products. At room temperature, it has five min. of tack time to support assembly adjustments before permanent bonding. Is designed for harsh environments. Combines UL 94 V-0 flammability rating with excellent electrical properties. Meets IPC-CC-830B, Amendment 1 requirements for insulation resistance and dielectric withstanding voltage. Can dry to film thickness of 50 to 200µm in single spray. Eliminates bubbles (<10min). When dispensed, it has viscosity that can be lowered by adding Dowsil OS-20 silicone fluid.
