| 摘要 |
The invention relates to a method wherein uncured urethane formulations are bonded to a cured rubber or synthetic rubber substrate in such a manner so as to provide greater bonding strength than has been achieved previously in urethane formulation bonding to rubber or synthetic rubber. The substrate is cleaned, a coating of a cyanoacrylate adhesive is applied, followed by a liquid or paste urethane formulation while the adhesive is still wet, and then the urethane is cured. |
