The Case of the Solvent vs. Carbon Based Urethane


Hi Glass Detective,

When choosing between a solvent based urethane and a carbon based urethane, what goes into your factoring?

Thank you for contacting the Glass Detective with your question regarding the use of urethane products. As you may know, there are a number of urethane products on the market and most (if not all) have very specific designated uses. Most auto glass adhesives are urethane and two-part (base with accelerator). Urethanes have been popular and widely used for the manufacturing of insulating glass unit assemblies for years as well. There are also building sealants made of urethane and so forth and so on. So the selection of an appropriate urethane product is dependent on its intended application. I am not familiar with which types of urethanes would be based on a “solvent or carbon platform” nor do I think it matters much. The appropriate sealant for a given application can best be determined from the manufacturer’s usage summary/recommendation information. All of the decent urethane manufacturers have recommendation information readily available to help you select the appropriate urethane for your application. Check them out online. I wish you good luck with your project.
