With so many adhesive technologies available, choosing the right material for your application can be a daunting task. Epoxies, silicones, and urethanes are three primary chemistries widely used in industrial applications. Each has its own benefits and drawbacks to consider.
Epoxy adhesives are available in one or two-part formulations with room temperature and heat cure options. Known for strong bonds, they are a common structural-grade adhesive choice and are best at bonding similar substrates like glass, metal, and wood.

Silicone adhesives are available in one or two-part formulations and are widely known for being incredibly elastic and thermally stable. Their environmental resistance properties make them a great sealant choice against water and air penetration.

Urethane adhesives, known for being durable and elastic, are available in moisture and heat cure systems, and work well in structural applications. They can bond both similar and dissimilar substrates including plastics, and typically don’t require surface preparation.

In some instances, existing adhesives on the market don’t have the right mix of chemical characteristics to meet unique application needs. For example, a company might be interested in the structural qualities of a particular epoxy adhesive, but their assembly process requires a faster cure time. Epoxy, silicone, and urethane adhesives can be modified or custom formulated to address these challenges. Other common reasons for developing a custom-formulated adhesive include:
ResinLab, a sister company of Ellsworth Adhesives, has a full-service laboratory and team of chemists who use a variety of equipment and testing methods to create a custom epoxy, silicone, or urethane. Common services performed during new product development include:
For many manufacturers, investing in a custom material provides long-term benefits for both the application and the bottom line.
Making the right material choice is crucial to ensuring your application is successful, with variables like cost, substrates, and assembly environment coming into play.
