SecurEdge Plus provides easy liner release and is available in wide range of sizes and shapes. |
King noted that the SecurEdge Plus foam core is uniquely manufactured with a microcellular polyurethane substrate for superior torque resistance and conformability. Additionally, the pad is engineered with two separate adhesives--one for the block and the other for the lens. The lens adhesive is specifically formulated to meet a wide range of super-hydrophobic coatings. Ensuring error-free application, the lens surface of the pad is identified with “SecurEdge Plus” printed under the adhesive.
“Proper application technique is crucial to maximizing lab efficiency and decreasing waste,” said King. “Lens slippage most often occurs as a result of improper application.”
For proper application, Saint-Gobain recommends thoroughly cleaning the lens to ensure that the adhesive completely bonds to the surface. The company also pointed out that since conformity is the leading cause of slippage and offset lenses, it is crucial to match the block and lens curvature to provide good wet-out.
Saint-Gobain distributes SecurEdge pads through DAC Vision, Dynamic Labs, Optical Laboratory Supply, Phantom Research Laboratories and Practical Systems. ■
