: What epoxies have VOC's in them? Except for products with thinners
: in them, like Rot-Fix, I'm not aware of any epoxies containing
: organic solvents or thinners. Every boat building epoxy I've
: seen is 100% "active ingredients".

Brian...I know it's their PR...but here is from MAS...

16 years ago, two guys restoring and building wooden boats got together and started MAS Epoxies. We wanted to build boats, not develop allergies to epoxy, so we set out to create a better epoxy, an epoxy that featured:

No Blush. Nobody likes washing and sanding between coats, and we found this was the biggest culprit of contact dermatitis. It was also a large contributor to paint failure. As a result, MAS is no-blush.
Easy mix ratios: we ended up with a 2:1 mix ratio, and this we could even eyeball and get close enough. It minimized the screw-up factor. To make it even easier, we now have one-push pumps! MAS is simple to use.
Blendable Hardeners. We wanted do be able to mix the hardeners - fast, medium and slow - to make any speed we wanted. Our shop rarely stayed the same temperature, so we wanted to customize the speed of cure based on the ambient temperature. This makes MAS epoxies very convenient to use.
Lower Viscosity: We required easier wet out of heavy fabrics and better saturation of wood fiber and core material - without cutting off brushes and having to stab the resin into the fabric or get rid of bubbles. MAS Low-Vis resin is the product of choice by top builders in many fields, and produces results like you see in the photo below. MAS has always been easy to use!
No VOC's. We knew that for healthier epoxies and safer shops, this was the only way to go. We wanted MAS to be safer to use, and it is!
For 16 years we've been offering superior epoxies, and we'd love to have you as a customer

It apears that the chemists at MAS believe that there are epoxies with VOC's

Just reading what they say...I'm not a chemist....But I use MAS epoxies
