DYNACOLL® 7000 - Polyester Polyols
EVONIK's DYNACOLL® 7000 product portfolio offers tailor-made raw materials for one-component, moisture curable hot melt adhesives and sealants (RHM).
DYNACOLL® 7000 grades are linear, medium molecular weight co-polyesters with primary hydroxyl functionality.
The product group is designed as a building block system.
Most DYNACOLL® 7000 polyester-polyols are compatible with each other.
However, partially incompatible but miscible systems are necessary in many applications as well.
