Evonik's DYNACOLL® S product range offers high molecular weight thermoplastic co-polyesters, used in hot melt and solvent-based adhesives and sealants.
The product range includes amorphous and crystalline grades with different melting points and various degrees of crystallinity or hardness. The crystalline grades provide high adhesive strength and good resistance to chemicals and solvents. For solvent based applications, amorphous grades are recommended due to their good solubility in non-chlorinated solvents and excellent adhesion to a wide range of substrates. There are two grades available:
- DYNACOLL® S - crystalline grades
- DYNACOLL® S - amorphous grades
DYNACOLL® S copolyesters are generally supplied as granules, usually in bags of 25 kg. They can be processed into following forms of applications: adhesive film, web or net, powder, paste, hot melt and solution.
