Surface preparation

The maximum performance of TECTYL 5638W-A can be achieved only when the surfaces to be protected are clean, dry and free of rust and oil. Non-galvanized steel and raw aluminum must be protected with an anticorrosion primer prior to application of TECTYL 5638W-A.


TECTYL 5638W-A is formulated to be used as supplied. Ensure uniform consistency prior to use. Avoid contamination with other products in pumps and lines. Valvoline recommends that the ambient and product temperature be 20-25°C at the time of product application. When applied by vacuum spray gun, spray at a pressure of 4 – 5 bars. Immediately after spraying clean the gun with a sufficient quantity of clean water. For larger surfaces, use a SST airless spray system with a ratio of 30:1 till 50:1.
DO NOT FREEZE TECTYL 5638W-A while curing.


When in the wet phase TECTYL 5638W-A can be removed with (hot) water. When dry, TECTYL 5638W-A can only be removed with Ethyl Acetate.
