The slurries are delivered pre-mixed to the appropriate consistency, weighed, and measured so there is no need to prepare the slurry on-site, saving users time and money.

R.T.U. slurries can be incorporated into high-temperature coating masking systems (R.T.U. M-7/B-4, M-10/B-4, M-107/B-4) where diffusion coating processes are above 1500°F or incorporated into low-temperature coating masking system (R.T.U. M8/B-4) where diffusion coating processes are below 1500°F.

APV’s R.T.U. slurry mixtures remain in suspension for significantly longer periods of time than on-site prepared slurries. These eco-friendly R.T.U. slurries also can be covered and re-used, significantly eliminating waste.
