For critical surfaces
With statutory requirements likely to become ever more stringent, the number of solvent-containing adhesives is bound to gradually decline. However, there are still areas – such as the construction industry – where shaped substrates demand the use of solvent-containing bonding agents. Cognis supports its customers with effective additives and the right polymer building blocks to ensure god flow behavior, problem-free dispersal and optimum wetting of the formulation components.
Cognis solutions: Emerox® azelaic acids are used for a wide range of applications.
Polymers prepared with azelaic acids deliver enhanced flexibility, toughness, good low-temperature physical properties and clarity.
Ecological benefit: Product manufactured from biobased raw materials
Performance benefits:
- Excellent chemical resistance
- Flexibility
- Excellent clarity
- Excellent adhesion to a wide range of substrates
- Easy adjustment of melting point properties
- Low viscosity
- High hydrophobicity
- Hydrolysis resistance
- Excellent bond strength
Cognis additives:
- Perenol® leveling agent for eliminating surface defects and problems such as poor substrate wetting, cratering, Bénard cells, floating and inadequate flow
- Texaphor® wetting and dispersing agents that simplify the addition of fillers. Due to the viscosity reduction achieved, the system filling rate can be increased.
- Rilanit® rheology additive for helping to control vertical stability.
