SolutionsWhat Are Specialty and Reactive Adhesives?

For diverse application needs, APPLIED Adhesives offers a variety of specialty adhesives that can help you operate efficiently, reliably, and with lower costs. Often used for specialty applications, advanced reactive adhesives use chemical reactions to create a bond. APPLIED’s innovative technologies include: web, cyanoacrylates, methyl methacrylate, epoxies, urethanes, and silicones.

Specialty & Reactive Adhesives

A type of hot-melt specialty adhesive, web adhesive is delivered as a nonwoven, web-like  material that handles similar to fabric.

Cyanoacrylates (CA) are a family of strong, fast-acting reactive adhesives that can bond quickly to a range of metallic, plastic, and rubber substrates at room temperature. CA single-component liquid adhesive is sometimes known as “instant glue” or “superglue.”

Reactive Methyl Methacrylate Adhesives (MMA) belong to a family of high-performance thermoplastics that bond metals, plastics, and composites. Compared to epoxies and CAs, MMA is more flexible. MMA is an aggressive two-component structural adhesive that has strong optical clarity, abrasion resistance, and physical strength.

Epoxy adhesives are versatile, thermosetting polymers, which can be used for adhesive, sealant, potting/encapsulation, impregnation, and coating. They are often used for structural adhesive applications and for electrical insulation. Two-component epoxies cure at room temperature and one-component epoxies cure with heat. Some of the key benefits of using reactive epoxies include: physical strength, resistance to chemical and environmental damage, and dimensional stability.

When cured, one- or two-component urethane adhesives can be rigid or flexible. Urethanes are not dependent upon moisture for curing, and bond well to a variety of substrates. They are often used in the automotive, marine, and wood industries.

Specialty silicone adhesives are designed to resist weather, water, and chemicals. One- and two-component silicone compounds are availablewith elastomeric adhesives and sealants being the most widely used. These polymeric materials contain the SI-O chemical group in their structure, which results in a gel-like consistency. Silicones can be used, and remain highly elastic, in environments with a continuous temperature range of -100°F (-75°C) to 390°F (200°C). For short periods, silicones also work up to 575°F (300°C).
