一般特征

Dispercoll C 2325 is an aqueous colloidal dispersion of a 2-chlorobutadiene polymer with a high rate of crystallization.
Dispercoll C 2325 is suitable for the formulation of aqueous adhesives for use in the footwear, construction, furniture, mattress and automotive industries. Dispercoll C 2325 is characterized in particular by good storage stability. It provides bonds with high initial strength and high heat resistance. The high amount of OH-groups gives a good adhesion and bonds with an outstanding heat resistance in combination with Bayhydur® 401-70.

储存条件

Dispercoll C 2325 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. This product is sensitive to freezing, and must be protected from cold. Frozen product is irreversibly damaged. Containers must be kept sealed as otherwise the evaporation of water will result in the formation of a non-redispersible film. Due to the process, the product can tend toward subsequent creaming. This manifests in the form of a very thin, brown layer which after some time becomes visible on the surface of the product. Prior homogenization of the product using a suitable stirrer is recommended each time product is removed from the container. Recommended storage temperature is 10º-25ºC.
