摘要
研制了1种聚氨酯密封胶专用双组分底涂剂。以多官能度的PAPI(多苯基多次甲基多异氰酸酯)为固化剂,以溶剂化的强极性共聚物、铬酸铅、偶联剂和其他助剂的混合物为主剂。显著提高聚氨酯密封胶对金属的粘结作用,剪切强度(钢/铝)达到10MPa。
A two component primer used for polyurethane sealant were polymerized. Component A was PAPI.Component B was made up of copolymers,lead chromate,coupling agent and other auxiliary agent.The primer enhanced adhesion of polyurethane sealant to metal markedly.
