What is liquid nails adhesive made of?

Liquid nail is made of epoxy which is a type of adhesive

There are epoxies on the market, but Liquid Nails construction adhesive isn't one of them.

I looked at the Material Safety Data Sheet for Liquid Nails Heavy-Duty Construction Adhesive. It contains four basic things: a resin to make it stick together, and they don't tell you WHAT resin but it ain't epoxy (because epoxy contains epoxides and polyamines which would have to be listed on the MSDS as they are hazardous in their own right, and they're not on the Liquid Nails MSDS); ground-up stone to make it thick; titanium dioxide to make it whiter than it would otherwise be; and seven different petroleum-based solvents.

The other kind of construction adhesive is polyurethane, which contains a modified diisocyanate and a modified polyol (modified so they can be mixed together and packaged in a tube without hardening; when they're exposed to the atmosphere they harden), and probably also the ground-up rock because uncured PUR is the consistency of honey--not what carpenters are expecting to see in their construction adhesive.

And since this question is also in the Makeup category...the glue for fingernails is cyanoacrylate-based superglue.
