polycel couplant can be used at elevated temperatures..?

tomorrow i am going to do UT lamination and thickness measurement in carbon steel pipe of dia 18inch and temp is 100˚c.,
I refered the standards asme sec v article 23 and I am clear about the thickness value correction factor., but I don't know whether i can use polycel or not., which couplant will be good to use..?

Wallpaper paste will evaporate (and stink). Use either a high temperature couplant (expensive) or, if it is allowed by your customer, grease that will stay viscous at this temperature

The 100C is not high temperature. Use either ultrasonic couplant agent on glycerol basis f.e. as Starsonic SS3
