7036 Blanchard Wax

Stronghold 7036 Blanchard Wax is primarily used for the temporary mounting of semiconductor wafers for dicing or grinding. Also, for use in mounting ceramics, ferrites, optical lenses and gemstones for grinding or other machining operations. Stronghold 7036 is resistant to most common solvents including water. Stronghold 7036 is solid at room temperature and starts to soften at 71-76C (160-170F) and has a viscosity of 6000 c.p. at 120C (250F). This product is not recommended for vacuum applications. As long as the temperature remains above 60C work pieces may be moved or positioned. After a few minutes at room temperature, the adhesive will set and machining can begin. Stronghold 7036 may be heated to 200C (400F) for a few hours if necessary. It may be kept in a vessel, heated up to a maximum of 120oC, for one or two days before deteriorating (the viscosity and flow point will gradually increase, solubility will decrease with time and high temperature). While acetone is by far the most effective solvent for 7036, there are some alternatives. Methyl Pyrrolidinone, Propylene Carbonate and Dibasic Ester work, apparently 100%, but slowly. Some customers have also used methylene chloride with 8 per cent methanol. Naturally, an ultrasonic bath and/or heat help to remove the adhesive. Ashing works well for some.
