First Contact™ Polymer Solution and Large Mirrors

Cleaning large mirrors, in fact any large optic surface, is a difficult challenge. Photonic Cleaning Technologies conquers the challenge with Spray Formula First Contact Polymer Solution.

Spray application of First Contact polymer allows complete coverage of any size optic surface using a completely touch-free process. No wipes, no brushes, no chance of scratching the surface!

First Contact™ polymer film protects the mirror too. Just leave the polymer film on the mirror for strong protection from water vapor, oxygen, and physical threats. Re-contamination is not a problem when the cleaned mirror is recoated with First Contact™.

Spray Formula First Contact can be applied using manual pumps or pressure sprayers. There are three sprayer styles available from Photonic Cleaning Technologies; we have hand pumped, hand compression pumped, and a heavy duty aluminum sprayer that can pressurized with a bicycle

There is some basic information for pressure spray application in Technical Bulletin 141 – Spray Application Note. More information can be found on the web or by contacting vendors of HVLP coating equipment.
