　　聚氨酯密封胶一般分为单组分和双组分两种基本类型，单组分为湿气固化型，双组分为反应固化型。单组分密封胶施工方便，但固化较慢；

　　双组分聚氨酯密封胶一般分为单组分和双组分两种基本类型，单组分为湿气固化型，双组分为反应固化型。

　　单组分密封胶施工方便，但固化较慢；双组分有固化快、性能好的特点，但使用时需要配制，工艺较为复杂。

　　两者各有发展前途。按是否有流动性，聚氨酯密封胶又可分为不垂挂型（non-sagging））和自流平行（self-leveling）。不垂挂型用于垂直面、倾斜面、天花板等场合，固化之前不会由于胶条自重而发生偏移、滑动或流动；而自流平型专门用于水平场合。按使用后的性质还可以分为不干型、半干型和全固化弹性体型。
