HydroTech 17mm x 30mm Oblong (roll of 1,000)

Special dual adhesive for lens side / back side 

The super dense strength of the foam substrate supports the torque from any edger/lens-curve combination to resist twisting during edging.  We use a differential adhesive system for “block-side” and “lens-side” uses.  The block-side adhesive allows for easy, clean deblocking; while the lens-side adhesive promotes an aggressive bond between the pad and hydrophobic surfaces.
