GRANVILLE, N.Y.--Saint-Gobain, based here, is introducing SecurEdge Plus, a new generation of blocking pads specially engineered for super-hydrophobic lenses. According to Saint-Gobain, the combination of SecurEdge Plus’ foam core base and high performance adhesive ensures optimal torque resistance and with no slippage. Its high performing adhesive eliminates the need for supplementary film and reduces total systems cost by minimizing waste and enabling a single-step solution.

 
SecurEdge Plus provides easy liner release and is available in wide range of sizes and shapes.
“Super-hydrophobic coatings are designed to repel dirt, water and unfortunately conventional pads,” said Geoff King, SecurEdge Product Manager for Saint-Gobain Performance Plastics, which is part of Saint-Gobain Corp., a major industrial company. “SecurEdge Plus accurately secures the lens in place during edging without compromising lens integrity.”

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.
