Stronghold 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 a clear solid at room temperature and starts to soften at 71-77C (160-170F) and has a viscosity of 6000 c.p. at 120C (250F). 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 120C, for one or two days before deteriorating (the viscosity and flow point will gradually increase, solubility will decrease with time and high temperature). This product is not recommended for vacuum applications.

While acetone is by far the most effective solvent for 7036, we have found a product that also works. "Ship Shape" from ISP evaporates almost not at all, and is not flammable. It does not remove 7036 as quickly, but it will remove completely. It claims to be 90% reclaimable. I guess the name and original use come from the use of fiberglass/epoxy in making ships or boats. We do not sell this material.  Please contact the manufacturer:

Some customers have also used methylene chloride with 8 per cent methanol. Naturally, an ultrasonic bath helps to remove the adhesive.

Stronghold 7036 is available in 7/8 inch diameter by 7 inch long glassine line tubes, or in 3-1/2 inch or 7 inch cast bars. Special packaging is available.
