Adhesives: PU and waterborne dispersions
Reactive PU adhesives and waterborne dispersion adhesives are distinct technologies. Components are selected after the process is defined.
Sealants
Selection between PU and silane-modified technologies based on joint movement and contacting materials.
Polyurethane systems
Component selection starts with the part and process. Foam and non-foam systems are evaluated separately.
Component compatibility and final properties require document review and trials. This component list is not a formulation.
