A kit for forming a composition for coating an overhead conductor comprising:
- a first part comprising:
- (i) a reflective agent comprising rutile titanium dioxide having an average particle size of ≥100 nm, sodium aluminosilicate (AlNa12SiO5), zinc oxide (ZnO) or copper oxide (CuO);
- (ii) a photocatalytic agent comprising ≥70 wt % anatase titanium dioxide (TiO2) having an average particle size (“aps”)≤100 nm;
- and (iii) one or more alkyl silicate binders;
- and
- a second part comprising:
- (i) a non-aqueous solvent;
- wherein, in use, the first and second parts are mixed together to form a composition which is applied to at least a portion of an overhead conductor in order to form a coating or film on at least a portion of the overhead conductor.

A method of retro-fitting an overhead power transmission or distribution line comprising one or more overhead conductors, the method comprising:
- spraying, painting, coating or applying a composition on to at least a portion of an overhead conductor, wherein the composition comprises:
- (i) a reflective agent comprising rutile titanium dioxide having an average particle size of ≥100 nm, sodium aluminosilicate (AlNa12SiO5), zinc oxide (ZnO) or copper oxide (CuO);
- (ii) a photocatalytic agent comprising ≥70 wt % anatase titanium dioxide (TiO2) having an average particle size (“aps”)≤100 nm;
- (iii) a non-aqueous solvent;
- and (iv) one or more alkyl silicate binders;
- and then
- allowing the composition to cure solely by moisture curing so as to form a coating or film on at least a portion of the overhead conductor.
