Huntsman Araldite AY 8629-1 Resin for HY 8628 Urethane Adhesive, 20 kg

Description

Araldite AY 8629-1 resin is the transparent resin side of the AY 8629-1 and Hardener HY 8628 two-component polyurethane adhesive system. The 20 kg package is sized for production bonding where clear appearance, cold cure, UV stability, and metal or plastic compatibility matter.

Araldite AY 8629 Benefits

• Transparent resin and transparent hardener support clear bond lines in visible assemblies.
• Cold-curing polyurethane chemistry avoids a required oven step for many production cells.
• Fast cure profile helps move bonded parts through staging and inspection sooner.
• UV-stable behavior supports applications where the bond area may see light exposure.
• Flash point above 100 C gives handling teams a useful reference for process planning.

This resin must be paired with the matching HY 8628 hardener and mixed at the specified ratio before use. It is selected for assemblies that need more flexibility than a rigid epoxy while still bonding prepared metals and plastics.

Araldite AY 8629 Applications

• Clear bonding of plastic housings, covers, lenses, and display-adjacent assemblies.
• Metal-to-plastic bonding in industrial, transportation, and electronics work.
• Production joints where ambient or fixture-assisted cold cure is preferred.
• UV-exposed parts where clear appearance must be protected during service.
• Large-volume adhesive programs that can use 20 kg resin packaging efficiently.

Surface Preparation And Mixing

Clean metal and plastic surfaces with a suitable degreasing agent before bonding. Where allowed, abrade the surface and clean again so the adhesive wets the prepared substrate rather than dust, oil, or mold release.

Blend resin and hardener until the mix is uniform, then apply steady contact pressure across the joint area. Confirm fixture time, open time, and full cure with current technical documentation before moving parts into service.

Technical Details And Documentation

Huntsman product information identifies the system as a cold-curing two-component polyurethane adhesive made from a transparent resin component and transparent hardener component. It also notes metal and plastic substrate use and the need for even contact pressure during cure. Review current product-family information from Huntsman before production use.
