Tectyl 435D is a hot application corrosion preventive compound which provides an effective barrier against atmospheric corrosion. The film is firm, tan in colour, and opaque.
Tectyl 435D is approved under Military Specification MIL-C-11796C, Classes 1 and 1A, QPL Reference Numbers M-6179 and M-6172, respectively.
The maximum performance of TECTYL 435D can be achieved only when the metal surfaces to be protected are clean, dry, and free of rust, oil, and mill scale. Daubert Chemical Company recommends that the metal substrate temperature be 50 - 95°F(10 - 35°C) at the time of product application.
TECTYL 435D should be applied to clean, dry metal surfaces in the hot (molten) state by hot airless spray or dip. (See application temperatures under Lab Data.) TECTYL 435D can be applied at warm, ambient temperatures by brush or swab.
