Beschreibung
Zusammenfassung:	The invention is directed to a Supercoating suitable for coating an optical fiber, to an optical fiber coated with said Supercoating, to a Supercoating for coating wire, to a wire coated with said Supercoating, and to a process to coat an optical fiber with a Supercoating. The Supercoating comprises at least two layers, wherein the first layer is a Primary Coating that is in contact with the outer surface of the optical fiber or wire and the second layer is a Secondary Coating in contact with the outer surface of the Primary Coating, wherein the cured Primary Coating on the optical fiber or wire has the following properties after initial cure and after one month aging at 85 °C and 85 % relative humidity: A) a % RAU of from 84 % to 99 %; B) an in-situ modulus of between 0.15 MPa and 0.60 MPa; and C) a Tube Tg, of from -25 °C to -55 °C; wherein the cured Secondary Coating on the optical fiber has the following properties after initial cure and after one month aging at 85 °C and 85 % relative humidity: A) a % RAU of from 80 % to 98 %; B) an in-situ modulus of between 0.60 GPa and 1.90 GPa; and C) a Tube Tg, of from 50 °C to 80 °C.
