Description
S-ST 5351 AERO is a one-component yellow viscous stripper based on methylene chloride for removing epoxy primers and polyurethanes from aluminium, magnesium, stainless steel and titanium. It clings to vertical and overhead surfaces, a film slows evaporation, and packing is a 5 gallon pail or a drum. S-ST 5351 THIN AERO is an amber two-phase liquid free of free acids and alkalis, approved for high-strength steels but not for materials sensitive to chlorinated hydrocarbons. S-ST 9100 AERO is a pink emulsion of neutral pH free of phosphates, borates, silicates and hydrogen peroxide, which removes the finish and the intermediate layer while leaving the primer, and eliminates sanding. According to the manufacturer, stripping time is cut by up to 33%, and the product complies with AMS 4872A (except magnesium) and BSS7432. S-ST 1270-5 and 1270-6 are white viscous emulsions free of aromatics, chlorinated solvents, phenol and chromates for selective removal of the finish from composites. Separately the range includes S-ST 6776 LO, S-ST 6813E and S-ST 6930.
How to choose
Choose the product by the coating and the substrate. The methylene chloride 5351 works on epoxies and polyurethanes on metals, 9100 is needed where the primer must be kept, and 1270-5 and 1270-6 are meant for painted composites. For chemical milling there are masks. S-MA 522 cures in air, peels off and protects against hot alkaline and acid solutions on aluminium, magnesium, steel and titanium. S-MA 551 LA-2 and S-MA 5580 G are removed by hand, and the two-component polyurethane S-MA M-4001 and M-4002 have 100% solids.
