Laminating epoxy for composite structures
KINETIX R246 supports hand lamination and machine impregnation with carbon, aramid and glass reinforcements; its hardener range allows working time to suit part scale.
Key considerations
- Compatible hardeners: H126, H128, H160, H161 and H162
- Published mix ratio: 100 parts resin to 25 parts hardener by weight
- Confirm pot life and cure schedule for the selected hardener in the current TDS
How to use
- Weigh accurately at 100 parts resin to 25 parts hardener by weight. An off-ratio mix will not cure fully, and adding extra hardener does not compensate.
- Mix thoroughly for at least 2 minutes, scraping the sides and bottom of the cup. Mixed epoxy left in a mass heats up faster; pour it into a wide tray to extend working time.
- Wet out carbon, aramid or glass by hand or with an impregnator, and roll out air.
Choosing a hardener
R246 is used with H126, H128, H160, H161 or H162. Each hardener gives a different working time and cure cycle: choose by shop temperature, part size and lay-up time required. See the TDS for exact times. For vertical surfaces or thick laminates, consider the thixotropic R246TX.
Storage and safety
Store dry and cool with containers closed. Wear nitrile gloves and eye protection, avoid skin contact and read the SDS before use.
