ABSTRACT:
A flexible membrane material of good water repellency comprising a base material and a water repellent layer on the base material, wherein the water repellent layer is a thin rubber layer having therein finely divided fluorinated resin grains scattered and rubbed in. This water repellent layer is firmly adhered to the base material and is substantially free from development of cracks during use. Furthermore the water-repellent layer prevents permeation of water and formation of a water layer on the membrane material. The flexible membrane material of the invention is suitable for use in the production of a radome for a satellite communication system, pneumatic membrane structures, or tents.
