Press Release Summary:
Optically clear, low movement, low shrinkage lens assembly adhesives include UV blocking grades, which exhibit excellent adhesion to PVA, CR-39, and CAP, and provide UV/visible protection to 410 nm. Design eliminates birefringence. Low shrinkage, low outgassing opaque adhesives are available in viscosities from thin wicking grades to thixotropic gels. Adhesives cure when exposed to low/medium intensity UV and visible light in 300-500 nm range.

Low Shrinkage, Low Movement Optically Clear Lens Bonding Adhesives
DYMAX Corporation offers a new line of lens assembly adhesives for precision bonding, mounting, laminating and fixturing applications. Specific application types include doublet bonding, lens laminating, mirror, prism and fiber optic assembly, as well as adhesives for use as temporary assembly aids.
Successful lens bonding applications include cameras, microscopes, tank periscopes, as well as eyeglass and sunglass lenses. Special UV blocking grades are available that exhibit excellent adhesion to PVA, CR-39 and CAP. These flexible lens bonders provide UV/visible protection to 410 nm.
DYMAX lens bonders have excellent adhesion to lens construction materials and to most metal, coated or painted frames and holders. Their low shrinkage and good flexibility characteristics minimize movement, eliminating birefringence common to more rigid types of formulations.
DYMAX offers low shrinkage, low outgassing opaque adhesives for precise optic alignment as well as optically clear grades for light path applications. Many of the adhesives are available in a range of viscosities, from thin wicking grades to thixotropic gels.
DYMAX adhesives are designed to cure fully when exposed to low to medium intensity UV and visible light in the 300-500 nm range. The adhesives have unlimited pot life and cure "on demand" in seconds, eliminating long cure time and racking so parts are ready to be shipped for J.I.T. delivery. DYMAX offers a full line of compatible UV light sources for most application needs, from high intensity spot wand lamps and flood lamps to tabletop conveyors.
DYMAX Corporation specializes in the formulation, manufacturing and service of advanced assembly adhesives, coatings, dispensers and curing systems.
