Description
LORD 3170 Part B is the amber hardener supplied for the LORD 3170 two-part epoxy adhesive system used on metals, glass, reinforced plastics, ceramics, and foam in cryogenic and general industrial bonding. This pint package supports 1:1 by-volume mixing with the matching resin and gives shops a practical size for repair, assembly, and qualification work.
LORD 3170 Part B Benefits
- Supports the 1:1 mix ratio required for the full 3170 structural epoxy system.
- Packaged in a pint can for bench work, maintenance stock, and smaller production runs.
- Pairs with an adhesive designed for cryogenic service and low outgassing aerospace work.
- Works with room-temperature cure schedules or faster heat-assisted processing when the full system is mixed and applied correctly.
- Useful on metal, glass, ceramic, reinforced plastic, and foam bonding jobs where the manufacturer calls for the 3170 system.
This hardener is typically selected when an operation already uses the matching resin and needs the correct companion component for controlled mixing. Parker’s technical data for the complete adhesive system lists a two-hour working time at 75 degrees F, handling strength in about 24 hours, and full strength in four days at room temperature, with faster processing available through applied heat.
Common Applications for LORD 3170 Part B
- Cryogenic bonding programs in aerospace and engineered equipment.
- Metal-to-metal assembly where the specified adhesive system must maintain strength at low temperature.
- Bonding glass, reinforced plastics, ceramics, and selected foam materials.
- Shop repairs, prototype builds, and qualification runs using the 3170 epoxy system.
- Assembly work that needs a measured pint package instead of a larger production container.
Compatible Materials
- Use only with LORD 3170 Part A resin in the manufacturer’s 1:1 by-volume ratio.
- Bonding substrates listed by Parker include metals, glass, reinforced plastics, ceramics, and foam materials.
- Prepared bond surfaces should be clean and free of oil, dust, mold release, rust, and related contamination before adhesive application.
