A laminate has at least two layers, at least one of which comprises a polymer having more than one perfluorocyclobutane group. Such polymers impart qualities of environmental protection, chemical and solvent resistance, hydrolytic stability, lubricity, low dielectric, hydrostatic stability, weatherability, flame resistance, chemical resistance,
scratch resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, and/or reduced moisture pick-up. Additionally, the coatings are optically clear, easy to apply either neat, in a solvent or otherwise, have relatively low cure temperatures for their temperature resistance, and exhibit insulating and planarizing capabilities.
层压板至少有两层,其中至少一层由具有一个以上全氟环丁烷基团的聚合物组成。这种聚合物具有环保、耐化学和耐溶剂、水解稳定性、润滑性、低介电强度、静水稳定性、耐候性、阻燃性、耐化学性、抗划伤性、表面钝化、憎水性、较低的表面折射率等特性、
耐划伤性、表面钝化、憎水性、较低的表面折射率、较低的表面摩擦系数、流体阻隔性、憎油性、热稳定性和/或降低吸湿性。此外,这些涂料还具有光学透明性,易于在溶剂中或以其他方式涂抹,固化温度相对较低,具有耐温性,并具有绝缘和平面化功能。
