Question 1

The Item for sale is 100% pure n-heptane, right? Better yet, can you tell me all the chemicals listed on the can?

Accepted Answer

Why does the SDS say 40% n-Heptane?  OK I checked the wiki:  "Heptane is commercially available as mixed isomers for use in paints and coatings, as the rubber cement solvent Bestine..."  The remaining 60% are the isomers of heptane.

Question 2

Is this safe to use in removing the protective paper from acrylic?

Accepted Answer

I work for a printing & graphics company. I use Bestine every day. It is safe on acrylic. Just be careful what you're using to rub the material with. Make sure the cloth, or cotton, is clean & soft. Change out the cloth frequently, as the adhesive you are removing builds up & causes smearing.

Question 3

Will this remove rubber cement from fabrics too? I spilled it all over my backpack

Accepted Answer

Bestine will thin rubber cement.  As the rubber cement thins, I believe it will soak further into the fabric.  Do not use bestine.  To get rubber cement  up from the fabric I would try to roll it out.   A little rubber cement rolled off the fabric, will roll into a ball of rubber cement.  Rubber cement sticks to rubber cement.  Use the little ball of rubber cement, dabbed onto the rubber cement on the fabric, to pull the rubber cement off the fabric.

Question 4

I need a way to dispense this better. We currently use a spray bottle but it seems to break the seal or something of that manner. any suggestions?

Accepted Answer

I have a container that looks like a cone-shaped oil can with a screw top that loosens but doesn't come off. It's the best way to use Bestine, and used to be sold along side the cans. It removes all kinds of petroleum and plant based adhesives. The original "oil cans" don't seem to be available, but there is a Polish brand that's similar, The Squirt Thinner dispenser by Double E Distributing. It sometimes shows up in an Amazon search.Bestine is toluene, which is NOT a flammable liquid. However, the vapor/gas is. We used to dip our fingers in Bestine and light it. The gas would burn, but not burn our skin. Art department mischief
