Overview
HS-2240 is a two-part, heat-cured adhesive for bonding, fixing and sealing ceramic lamp bases to quartz glass tubes.
Designed for high-temperature lighting assemblies, with a continuous service range of −40°C to +600°C and a short-term peak of +800°C. Validate the joint design and cure process on your actual parts.

Applications
- Ceramic lamp base to quartz glass tube bonding
- High-temperature equipment lighting assemblies
- Quartz heating tube and lamp end sealing
Application & handling
Clean and dry the bonding surfaces. Mix A:B = 1:1–2 by weight until uniform. Let the mixture stand for 4 hours to release air before coating or filling. Use within the same day; discard material that has formed lumps or hardened.
Standard cure: 80–100°C for 2–4 hours, then cool with the oven. For the lower-bubble process: hold at 40°C for 2 hours, then 60°C for 2–4 hours and cool with the oven. The strength values are referenced to 100°C × 2-hour cure; validate other cure schedules on your actual parts. Room-temperature cure is very slow and is not recommended.
Fully cure before further assembly or testing. Keep cured parts protected from prolonged humidity. Wipe excess uncured adhesive with a water-dampened cloth and request the current SDS for safe handling.
Confirm current grade-specific technical and safety data, and validate performance on your actual parts before production.
