The solution of vinyl resin can not be directly contacted with iron during the storage process to maximize the

stability. It should be stored in the plastic container with the phenolic-based liner, or non-swelling and no

plasticizer migration.

Vinyl resin should be stored under dry and ventilated conditions and at room temperature ( below 25 ℃),

avoiding direct sunlight. Under these conditions, the product has a shelf life of at least 12 months. If the resin

is kept beyond the recommended shelf life, it is not necessary unusable, but the user should perform a quality

control on the properties relevant to the application. High temperature as well as direct sunlight will shorten

shelf life and accelerate its ageing and discoloration.
