CEMEDINE 1565 Clear Epoxy Adhesive for Transparent Optical Bonding

CEMEDINE 1565 Clear Epoxy Adhesive is a two-component, solvent-free epoxy system developed for transparent bonding of glass, rigid plastics, optical components, decorative parts, and mixed-material assemblies. When the 1565 base resin is combined with the standard 1565 hardener, the system uses a practical 1:1 mixing ratio by weight and provides an approximate pot life of 30 minutes at room temperature. Its light-colored transparent appearance helps create discreet bond lines where clarity and finished appearance are important.

The adhesive is especially valuable for glass crafts, plastic crafts, lighting fixtures, indoor decorative products, nameplates, handles, accessories, optical lenses, and prisms. Its refractive index is approximately 1.57, supporting transparent optical bonding where visible distortion should be minimized. Because the formulation does not depend on solvent evaporation, it cures without significant shrinkage, expansion, or by-product formation, helping reduce internal stress and cracking at the bonded interface.

Key Benefits of CEMEDINE 1565 Clear Epoxy Adhesive

CEMEDINE 1565 Clear Epoxy Adhesive combines a near-transparent cured appearance with useful flexibility and impact resistance. Its epoxy-polysulfide chemistry creates a bond layer that is less brittle than many conventional rigid epoxies, allowing the joint to tolerate vibration, impact, and movement. The manufacturer also identifies good resistance to water, moisture, ultraviolet exposure, oil, and various chemicals.

The standard 1565 base and hardener are medium-viscosity liquids, with typical viscosities of approximately 1.5 Pa·s at 23°C for each component. This supports smooth spreading across glass and plastic surfaces while remaining practical for controlled manual application. For glass bonding, the recommended coating weight is approximately 100 to 150 g/m². Only light contact pressure is normally needed during curing because the system does not significantly shrink or expand.

Applications for CEMEDINE 1565 Clear Epoxy Adhesive

CEMEDINE 1565 Clear Epoxy Adhesive can bond glass, rigid PVC, acrylic, polystyrene, metals, wood, decorative laminates, and selected compatible plastics. It is particularly suitable for lenses, prisms, glass ornaments, lighting components, display pieces, accessories, and interior decorative parts. Its clarity, flexibility, and environmental resistance make it useful where both appearance and dependable adhesion are required.

The product is not recommended for polyethylene, polypropylene, PTFE, fluoropolymers, or other difficult low-surface-energy plastics without a validated surface-treatment process. Actual adhesion depends on substrate grade, surface preparation, joint design, adhesive thickness, mixing accuracy, curing temperature, and service conditions. Buyers should test representative parts before mass use, especially for assemblies exposed to heat, water, impact, or strict optical inspection.

How to Apply CEMEDINE 1565 Clear Epoxy Adhesive

Before applying CEMEDINE 1565 Clear Epoxy Adhesive, remove moisture, dust, rust, grease, oil, release agents, and other contamination from both surfaces. Use separate tools for the base resin and hardener to prevent cross-contamination. Measure the required quantity at the standard 1:1 weight ratio, then mix thoroughly in a flat-bottomed container until the material becomes uniform.

Apply the mixed adhesive promptly, join the components, and secure them against movement. At room temperature, the standard system typically cures in approximately five to six hours, although waiting about 24 hours before normal service is recommended. Controlled heating at approximately 60°C can shorten curing to around 60 minutes when the bonded materials can safely tolerate heat.

Storage and Safety of CEMEDINE 1565 Clear Epoxy Adhesive

Store CEMEDINE 1565 Clear Epoxy Adhesive in its original closed containers and follow the current product label and safety data sheet. Avoid direct skin and eye contact, use suitable gloves and workplace ventilation, and clean tools before the adhesive hardens. Keep the base resin and hardener closed when not in use to reduce contamination.

For buyers seeking a transparent two-part epoxy for glass, rigid plastic, lens, prism, lighting, and decorative assembly, CEMEDINE 1565 Clear Epoxy Adhesive offers simple mixing, low shrinkage, reliable clarity, flexible bonding, and durable performance. It is a practical professional choice for optical work, product assembly, craft production, and maintenance where the bond line should remain strong and visually discreet.
