Shown in this video are two samples, each coated with Guernsey’s (G14) durable gold. One is treated with a secondary hydrophobic coating. To demonstrate, both have silicone oil applied. Once the oil has dripped over the coating, they are cleaned with alcohol followed by an acetone wipe. The treated sample shows the clear effect of GCL’s hydrophobic coating.

In a previous video, Guernsey’s (M14) silver is highlighted depicting a 6” mirror treated with a secondary hydrophobic coating on half the surface. Using water over the substrate, the treated side shows a beading up and repelling of water droplets.

Adding our hydrophobic coating to most of GCL’s thin-films including metallics and AR coatings, will assist in protecting the coated surface from debris, repel water and some oils, without compromising optical performance.

Hydrophobic coatings can be applied to most coatings on glass, metals and plastic substrates.

*Our gold coating (G14) has environmental and mechanical durabilities the same as the aluminum and silver coatings while reflecting >96% average from 650-1700nm and >98% average from 1.7 – 20 microns at 0º AOI.

*Our silver coating (M14) withstands the same humidity and durability specifications while delivering reflectivities of >96% average from 480-1100nm and >98.5% from 1.1 – 20 microns at normal incidence.
