We hope to be able to help out a customer today with a health & safety problem. They use wax to temporarily hold glass lenses in position whilst polishing, lapping and so on – it’s quite common. These are also called blocking agents.
The difficulty for this customer is that they use xylene to remove the wax afterwards, and that’s a pretty nasty chemical.
We have asked them to test our Opti-tec Water Soluble Temporary Adhesives. These thermoplastic adhesives are stable at ambient temperature water, but dissolve completely and safely at elevated temperatures. So, non flammable, safe to use, simple to dispose of – solutions to all the issues of using solvents.
