Saint-Gobain offers a new guide to help labs maximise efficiency by choosing the right blocking pad for a variety of lens materials and coatings, including super-hydrophobic
As blocking pads are the only components that hold lenses in place during edging, selecting the correct type can decrease waste and reduce total systems costs.
Saint-Gobain's blocking pad guide features tips to help labs properly choose and apply edging pad solutions, which is vital to protecting upstream investment during this final process.
The guide also educates labs on the conformity and adhesion properties of different edging pads.
"With the development of advanced lens materials and coatings, such as anti-reflective and super-hydrophobic, blocking pads play an increasingly important role in prescription fulfillment," says Geoff King, SecurEdge product manager, Saint-Gobain Performance Plastics.
"Using the proper edging pad can help labs decrease waste by ensuring proper torque resistance and reducing instances of residue or ghosting on a lens".
Saint-Gobain's product family of edging pads includes a wide range of solutions for lens materials and coatings, including SecurEdge Plus, which is specifically engineered for super-hydrophobic lenses.
SecurEdge Plus is a single-step edging solution and its high-performance adhesive will not mar lenses, eliminating the need for supplementary film and reducing total systems costs.
Saint-Gobain's SecurEdge blocking pad is ideal for a variety of lens coatings and offers unique reinforced foam for optimum torque resistance and conformity.
The OP7 series blocking pad features a strong foam core and an acrylic adhesive, making it an economical alternative for non-super hydrophobic coatings.
"Each Saint-Gobain pad is specially engineered to meet varying edging demands," says King.
"Proper selection and application is critical to maximizing laboratory efficiency and the guide provides a quick and easy reference to ensure optimal results."
