USP Class VI Adhesives
USP Class VI Approved Adhesives for Medical Device Applications
Master Bond’s biocompatible adhesives are designed to meet the needs of medical device manufacturers. Compounds withstand various types of sterilization methods.

Epoxy Technology EPO-TEK® 301 Spectrally Transparent Epoxy
Categories: Polymer; Thermoset; Epoxy

Material Notes: Product Description: EPO-TEK® 301 is a two component, room temperature curing epoxy featuring very low viscosity, and excellent optical-mechanical properties.

Advantages & Application Notes:

  • Semiconductor: optical glob top or underfill; adhesion to common wafer passivation, solder mask and flex circuits; compatible with LED die, Si, GaAs.
  • PCB: general potting and protection over FR4, flex, or ceramic PCBs.
  • Medical:
    • It is NONTOXIC—complying with USP Class VI Biocompatibility standards. Suggested for medical devices such as catheters, hand and tooling, dental, and endoscopic products; adhesion to stainless steel, titanium, and most plastics; resisting sterilizing techniques like ETO, gamma, and autoclave (65°C/1 hour cure); resisting X-ray radiation; potting and protection of scintillator crystals; CT Detector packaging; adhesive for the optical beam pathway in photo-diode arrays.
    • Compatible with CIDEX® OPA sterilization.
  • Fiber Optic: adhesive for glass and plastic fibers; wicking into fiber bundles used in patch cords, endoscopes or sensor devices; adhesive/seal/encapsulant used for fiber packaging and components; transmission of IR up to 2500 nm; terminating fibers into ferrules; fiber coupling and splicing.
  • Opto-electronic
    • LCD/LED adhesive for laminating glass layers; adhesion to PET plastic; general potting, encapsulation, and protection; spectral transmission in VIS and IR light; adhesive/encapsulant for VCSEL’s packaged devices; resisting yellowing per ASTM D1925; adhesive for precision optics including lens, prism, beam splitter cubes, mirrors, and diodes, found in medical, university, or research communities.
  • NASA approved, low outgassing epoxy
