Bonding Processes and Agents

Bonding Processes and Agents

LSO uses several types of medical grade adhesives including:

  • UV light curable adhesives
  • Epoxy resins
  • Cyanoacrylates

We also have curing systems to optimize the speed of automated assembly, which allows for 100% in-line inspection, and increase throughput:

  • UV curing spot lamps
  • Flood lamps

Solvent Bonding

Solvent bonding is a common technique used for joining parts molded of thermoplastic resins. During this bonding process, the solvent dissolves the surface of the two mating parts and allows the material to flow together. Once the solvent evaporates, the result is material-to-material bond. Many medical device plastic based materials can be solvent bonded in an application where ultrasonic welding won't work.

Cyanoacrylate Adhesives

LSO inventories different viscosities of cyanoacrylate formulas at their facility. Medical cyanoacrylate adhesives offer exceptional product stability and faster cure speeds over other types of instant adhesive products.

Medical-grade cyanoacrylate adhesives offer exceptional product stability and faster cure speeds over other medical cyanoacrylate instant adhesives. This type of medical device instant adhesive can replace many different grades of both methyl and ethyl cyanoacrylates due to their ability to adhere to a wide selection of substrates.

These types of agents are:

  • Solvent Free
  • ISO 10993 approved
  • Excellent for bonding opaque and difficult-to-bond-to substrates
  • Low odor, low bloom
  • Instant adhesive bonds
  • Wide range of viscosities

UV Cure Bonding

Light-curable adhesives cure in seconds upon exposure to longwave ultraviolet light and/or visible light, heat, or with an activator. Light-curable adhesives optimize the speed of automated assembly, enable 100% in-line inspection, and increase product throughput. Industrial adhesives are available for plastic sealing, metal bonding, and glass assembly, as well as for joining dissimilar substrates.

Epoxy Resins

Epoxy resins are made of tightly linked adhesive polymer structures that are often used in surface adhesives and coatings. Epoxy resins are capable of forming tight cross-linked polymer structures characterized by toughness, strong adhesion, and low shrinkage. Epoxy adhesives are nearly unmatched in heat and chemical resistance.
