Epoxy resins are low molecular weight pre-polymers or higher molecular weight polymers which normally contain at least two epoxide groups. The epoxide group is also sometimes referred to as a glycidyl or oxirane group.
Different grape varieties thrive in different climates, but typically do best in U.S. Department of Agriculture plant hardiness zones 5 through 9. Although highly perishable, when stored correctly, grapes can last up to six weeks after harvesting.
Place your grapes in the refrigerator immediately upon arriving home. Grapes will stay freshest when stored at temperatures between 30 and 32 degrees Fahrenheit (-1 and 0 degrees Celsius).2. Place grapes into a sealed plastic bag or airtight container without washing them. Washing your grapes will accelerate the ripening process, and will cause them to spoil quickly within 7 days. Before placing in the freezer, make sure to line the grapes on a cookie sheet to prevent them from freezing and sticking together, then place them into a separate storage container after each grape has become individually frozen.
