technical data sheet TT-P-1757B ty.i or ty. ii, cl.c zinc chromate primer page 2 of 2 surface preparation: steel, non-ferrous metals & galvanizing. surface to be coated must be clean, dry, and free of all foreign contaminants including grease, oil, dirt and paint. clean in accordance with sspc-sp- 1. most metals should be sanded, except aluminum, which must have a base coat of pre- treatment wash primer mil-c- 8514c, followed by one wet coat of TT-P-1757B ty.i or ty. ii, cl.c alloys that oxidize must be lightly sanded to remove all loose material. dirt and dust are best removed with a stiff bristle brush and by compressed air. for exterior use and non-ferrous metals, it is recommended that TT-P-1757B ty.i or ty. ii, cl.c be applied over pre-treatment coating conforming to mil- c-8514c or dod-p-15328d. grease and oil should be removed by cleaning with appropri ate solvents such as mineral spirits, lacquer wash thinner or xylene. mixing/application instructions: apply by spray, brush or dip to deposit a hiding coat of primer. a wet coat is necessary to secure maximum adhesion and corrosion inhibiting properties. for spraying, thin up to 15% by volume or as needed with thinner per tt-x-916 or mil-t-81772b ty.iii. precautions: keep out of reach of children. use with adequate ventilation. avoid contact with skin and eyes. read material safety data sheet before using. contents are flammable. free datasheet http://
