Master Bond epoxy adhesives are freshly prepared to maximize shelf life. The date of manufacture is clearly shown on each label. Technical datasheets include storage directions and shelf life for every product. If not stored properly, the product will not perform as it is supposed to.

Two component epoxies

Typical storage conditions for two component epoxy adhesives are ambient temperatures, 20-25°C (68-77°F), in a dry location in original unopened containers. Once containers are opened material should be kept free from moisture, dust, high/low temperatures, etc. Containers should be stored in well ventilated areas, tightly sealed with original lids. Additionally, applicators such as spatulas should be thoroughly cleaned to prevent cross-contamination.

Premixed and frozen epoxies

Premixed and frozen two part epoxies are packaged in syringes ranging from 1 cc to 10 cc and shipped in specially insulated cartons packed with dry ice. When stored at -40°C (-40°F) the shelf life is 6 months. These systems cure at room temperature and cannot be re-frozen or re-used once they are thawed out.

One component epoxies

Specific one component epoxy systems also need to be stored at 5-10°C (40-50°F). These products should only be dispensed when they are brought to ambient temperature. Many one component systems are available for use in syringe and cartridge applicators.

Safety instructions

Check the product specific technical datasheets (TDS) and safety datasheets (SDS) for proper handling and storage. It is important to note that special care must be taken when storing hazardous and flammable materials. All pertinent local, state, federal and international regulations need to be followed.
