Tectyl 437D Corrosion Preventive Compound
Tectyl 437D is a hot application corrosion preventive compound which provides an effective barrier against atmospheric corrosion. The film is semi-firm, tan in color and opaque.
Surface Preparation of Tectyl 437D Corrosion Preventive Compound
- The maximum performance of Tectyl 437D 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.
Application of Tectyl 437D Corrosion Preventive Compound
- Tectyl 437D 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 437D can be applied at warm, ambient temperatures by brush or swab.
