Crjlover...type 1 will give you a very short holdover time,if i'm not mistaken.I remember once using type 1,cause they had nothing else,and doing deiceing at the holding point -around 4 min holdover time in that case.
Type I fluidsare unthickened de-/anti-icing fluids on a glycol basis,and they provide protection ONLY when no precipitations occur.Under continuous precipitation the protection they provide diminishes rapidly because the fluid film on the plane is diluted by the precipitation and eventually washed off.
