DOWSIL™ 1-2620 Dispersion RTV Elastoplastic Conformal Coating is a one-part, transparent, low-viscosity silicone resin solution designed to protect electronic components. Upon curing, it forms a tough, resilient, and abrasion-resistant surface. This solvent-borne resin coating cures at room temperature, with an option for mild heat acceleration after solvent flash-off to speed up in-line processing. It contains a UV indicator to facilitate automated inspection and meets UL 94 V-0 flammability standards, as well as MIL-I-46058C and IPC-CC-830B specifications.
