• Urethane Adhesive - Typically flexible and bond well to plastics. However, they usually require primers on
metal surfaces to protect against corrosion. Urethanes have good seam sealing and NVH qualities and are
frequently the optimal choice for seam sealers. They are sensitive to moisture during cure, packaging and
storage. Single component urethanes usually have a much shorter shelf life than two component urethanes.
Mix ratios are critical for urethanes. In most cases it cannot vary more than ± 5%. Therefore, hand mixing
is not recommended. Urethanes are the most unforgiving of the three chemistries with regards to mix
ratio accuracy.
