Drying and hardening do not occur unless epoxy resins and epoxy hardeners, which are components in epoxy systems, are mixed with each other. Products stored in closed packages in accordance with the storage conditions can wait without losing their properties.
- In case of hardeners waiting in their packaging for a long time, yellowing may occur. This does not significantly alter other performance data other than discoloration of the epoxy hardener. It does not prevent use.
- On the other hand, for resins that are kept in their packaging for a long time, crystallization problem may occur due to exposure to cold air (below 10 C), depending on climate changes or storage conditions. Crystallized resins can be restored by heating. This process does not change the performance data of the epoxy resin. It does not prevent use. For detailed information about crystallization, you can review our article titled “Crystallization of Epoxy Resin”.
