LENS BOND SK-9

LENS BOND Type SK-9 is a single component, modified Acrylate / Methacrylate Photopolymer. This low viscosity liquid polymer is easy to apply, particularly when thin cement films are required. It is quick to pre-cure as well. Type SK-9 cures by exposure to long-wave ultraviolet light (365 nm). Its high wetting and low shrinkage combine to give a superior bond. LENS BOND Type SK-9 practically eliminates air bubble problems due to its low viscosity.

LENS BOND Type SK-9 shows extremely high adhesion to many types of plastics which are usually problematic to be bond. SK-9 can generally be used when bonding plastic / plastic materials, plastic / glass, plastic / metal, as well as substrates with low UVtransparency (40 – 60 %).

Curing Times

Pre-Curing:
Room temperature 22°C (72°F) using a long-wave black light of 15 watts (365 nm) approx. 25 mm above the element ca. 3 - 5 seconds

Full-Cureing: Room temperature 22°C (72°F) using a long-wave black light of 15 watts (365 nm) approx. 25 mm above the element. ca. 1 hour
