Searching for suitable glue for fabric covering, I came across a water based glue based on acrylics. It is used to glue Ferarri upholstery and I was assured that it underwent rigorous environmental testing. I received my sample on last Friday and had a chance to make some test samples as in image 1. Polyester fabric, from Aircraft Spruce and fabricl is glued to each other and to wood. Wood was bare. A couple days later I will try to separate them. Application is similar to EkoBond. You need 70-80 degrres Celcius of heat to activate the contact glue. The brand is Intercom Ecostick 1820 1K.
