PROCESSING CONDITION
After mixing in the recommended ratio, use Zepoxy CWB to impregnate reinforcements such as glass, aramid, or carbon fibers. To achieve the required temperature resistance and optimal mechanical properties, a post-curing process is essential: 12–36 hours at room temperature, followed by 2 hours at 80°C and 4 hours at 100°C. Processing at a minimum of 20°C ensures an excellent curing start of the Zepoxy CWB system.
MIXING
The mixing ratio must be accurately followed to achieve perfect results. It is not possible to change the ratio, as doing so may result in improper curing and lower mechanical properties. Pour the hardener first and then the resin. The mixed components should be thoroughly mixed for 3–4 minutes to ensure an even consistency. To avoid bubble formation, mix slowly for 5–10 minutes.
