DYNACOLL® 7000 SERIES
With its DYNACOLL® 7000 polyester-polyols Evonik offers tailor-made raw materials for one-component moisture-curable hotmelt (RHM) adhesives and sealants. DYNACOLL® 7000 products are linear copolyesters with primary hydroxyl functionality and medium molecular weight.
Depending on their morphology the product range is divided into three basic groups:
DYNACOLL® 7100 series amorphous, solid
DYNACOLL® 7200 series liquid, pasty
DYNACOLL® 7300 series partially crystalline, solid
The product group is designed as a building block system, most DYNACOLL® 7000 polyester-polyols are compatible with each other. Partially incompatible but miscible systems are, however, necessary in many applications as well.
DYNACOLL® 7000 copolyesters are usually supplied in 25 or 30 kg and 190 or 200 kg steel drums. Liquid bulk deliveries are available on special request.
