Contact adhesives are the class of adhesives that bond to themselves upon self-contact. These are typically used to bond items with the large surface area, like plastic laminate countertops in kitchens and bathrooms, or any laminate that is bonded to the wood or particle board…
Solvent-based contact adhesive formulations typically consist of a solvent or solvent blend, in which rubber, resin, and additives such as anti-oxidants, fillers etc. are dissolved. The solvent used for such formulations generally include:
These solvents are classified as hazardous air pollutants (HAPs) by theU.S Environmental Protection Agency and long-term exposure to these solvents can:
This prompted researchers from UMass Lowell, Toxics Use Reduction Institute (TURI) and ITW Polymer Sealants North America to identify alternatives to toxic conventional solvent systems.
Let's take a look at this approach in detail:

The solvent used for such formulations generally include:
- Toluene
- Hexane
- Methylene chloride and more
These solvents are classified as hazardous air pollutants (HAPs) by theU.S Environmental Protection Agency and long-term exposure to these solvents can:
- Impair central nervous system
- Cause cancer
- Affect the central nervous system
This prompted researchers from UMass Lowell, Toxics Use Reduction Institute (TURI) and ITW Polymer Sealants North America to identify alternatives to toxic conventional solvent systems.
