HCG-150 AC Lens Hardcoating Sol (Primerless)

  • Product Details

HCG-150 AC Lens Hardcoating Sol (PRIMERLESS) is a proprietary formulation of thermally curable polysiloxane resins in alcohol solvent. Typical use could be found on acrylic lens hardcoating which forms a thin optically clear layer with superior resistance to scratch and abrasion. Users could enormously benefit from the ease of handling and reduced operational cost as HCG-150 does not require a primer to achieve adhesion.
