A poysiloxane resin composition includes a blend of silanols, colloidal silica, an ultraviolet-absorbing material, and a dye for correcting the color of a film formed from the resin composition. The silanols include a silanol from the group having the formula R.sub.w Si(OH).sub.x or R.sub.y Si(OR').sub.z where (w+x) or (y+z)=4, and R and R' are organic radicals without any crosslinking sites, silanol from the group having the formula R'Si(OR'').sub.3 where R' is a hydrogen atom or an organic radical and R'' is an organic radical containing a crosslinking site. The resin may be cured at 420.degree. F. The ultraviolet-absorbing material may be a benzophenone, a benzotriazole, or a benzothiazole. A process for forming the resin composition includes reacting the silanols and the ultraviolet-absorbing material under continuous agitation for about six hours.
