application
Dispercoll® (Dispercoll®) C 74 is used in the formulation of water-based adhesives, used in shoemaking, construction, furniture, mattresses, automobiles and other industrial fields.

Package
120kg plastic drum, 1000L container, tank car.

store .
Stored in the original airtight container, at 23°C, the shelf life of Dabike® C 74 is 6 months. Storage temperatures above 30°C should be avoided. The storage temperature should not be lower than 5℃, otherwise the product will freeze and solidify. A solidified Dripped® C 74 will be completely ineffective. The packaging container must be tightly closed and protected from direct sunlight, otherwise the evaporation of water will cause it to form a non-redispersible polymer film.

Waste Disposal .
Useless DIPPE® product residues should be incinerated in accordance with local regulations, and polymer dispersions should be handled under special supervision and must not contaminate soil or surface water.
