DOWSIL 1-4105 Conformal Coating is suitable for use as a protective coating for rigid and flexible circuit boards
Solventless heat cure conformal
coatings are designed for rapid
processing at low temperatures
(below 125°C). They require some
heating to cure, offering long bath at
room temperature. Like the roomtemperature-curing
elastomers, these
products offer optimum stress relief -

All surfaces should be thoroughly cleaned and/or degreased with DOWSIL™ brand OS
Fluids, naphtha, mineral spirits, methyl ethyl ketone (MEK) or other suitable solvent.
Solvents such as acetone or isopropyl alcohol (IPA) do not tend to remove oils well, and any
oils remaining on the surface may interfere with adhesion. Light surface abrasion is
recommended whenever possible, because it promotes good cleaning and increases the
surface area for bonding. A final surface wipe with acetone or IPA is also useful. Some
cleaning techniques may provide better results than others; users should determine the best
techniques for their particular applications. -
DOWSIL 1-2620 Low VOC Conformal Coating version is supplied with a lower VOC content compared to that of the DOWSIL 1-2620 Dispersion and has equivalent Mil spec, IPC-CC-830 and UL recognitions.
RTV elastoplastic conformal coatings have firm, dry surfaces for better handling and
abrasion resistance after cure. Various viscosity versions facilitate different application
methods. They require atmospheric moisture to cure (no ovens) and their cure rates can be
accelerated by mild heat. Conformal coatings are materials applied in thin layers onto
printed circuits boards or other PCB system assembly substrates
