OP7
Finish Blocking Pad for General Use OP7 is an economic, yet reliable, performing blocking pad for general use. It is constructed with a strong polyurethane foam that is engineered to resist the rotational forces resulting from the edging process. With strong acrylic adhesive on both sides, it will not slip during the edging process, yet removes cleanly with no residue or adhesive marring.
- Strong polyurethane foam core assures a precise hold
- Acrylic adhesive on both sides for good quick-stick and clean removal
- Flexible and conformable for good wet-out to a wide
OP5
Finish Blocking Pad With Unique Reinforced Foam Saint-Gobain® Norbond® OP5C finish blocking pad was developed with a unique construction never before used in bonding pads for the lens edging process. By utilizing a unique internal reinforcement technology, the tape is able to resist high rotational forces and prevents off-axis movement during the edging process. The conformable foam surface features a modified acrylic adhesive that ensures good contact to a wide range of lens materials, coatings and curvatures.
- Unique reinforced foam resists torque forces in the X-Y direction
- Soft foam surface conforms to lens curvature
- Modified acrylic adhesive system adheres to wide range of lens coatings
OP45
Saint-Gobain® Norbond® OP45 is a new generation blocking pad designed specifically to bond to the latest generation of low surface energy super hydrophobic coatings. Based on the proven design of the highly successful OP Series, OP45 improves on this with the incorporation of a unique adhesive system engineered specifically to perform on the latest generation lens coatings. Good quick-stick, outstanding shear performance and easy release make this the ideal product for single-step edging.
- Microcellular polyurethane foam tape core provides good surface conformability and resists torque forces
- The adhesive for the lens surface is formulated to adhere to a wide range of the latest super hydrophobic coatings
- The adhesive system for the lens surface is identified to ensure error-free application
- Available in a wide range of die-cut shapes and sizes
- Suitable for a wide range of block types and edging Equipment
