​

Answer 1

Polyurethanes and Epoxies are adhesives compounds

Explanation:

• PUR is the good compound and compete with other compounds such as Epoxies and acrylics.
• PUR have other adhesive such as structural adhesiveness includes polyimides, silicones and the polysulfides.
• PUR adhesives is formed by the reaction with different compounds such as isocyanates with polyols.
