General Characterization

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.

Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 10 - 25 °C.

- Protect from frost, heat and foreign material.

General information: This product is sensitive to frost, 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.
