OCA Optical Adhesive for PMMA and COC Diffusion Bonding. Specialty optically clear adhesive designed for bonding PMMA (acrylic) and COC (Cyclic Olefin Copolymer) substrates used in microfluidic chips, optical components, and specialty display applications requiring high optical clarity and chemical compatibility.
Frequently Asked Questions
What is PMMA and COC diffusion bonding and why does it require specialty OCA?
PMMA (polymethyl methacrylate / acrylic) and COC (Cyclic Olefin Copolymer) are optical-grade plastics used in microfluidic chips and optical components. Standard OCA may not adhere well to these materials or may cause chemical incompatibility. This specialty OCA is formulated for strong, optically clear bonding specifically on PMMA and COC substrates.
What applications use PMMA and COC OCA bonding?
This adhesive is used in microfluidic chip fabrication, lab-on-chip devices, optical waveguides, medical diagnostic devices, and specialty optical components where PMMA or COC substrates require transparent, chemically compatible bonding.
Is this OCA adhesive biocompatible for medical and diagnostic applications?
This adhesive is formulated for use in laboratory and medical diagnostic applications. Please contact our team for biocompatibility certification details and chemical resistance specifications relevant to your specific application requirements.
What curing method is used for this PMMA/COC OCA adhesive?
This OCA adhesive uses pressure-sensitive bonding, similar to standard OCA film. No UV curing is required. The bond is activated by applying controlled pressure during the lamination process. Please contact our team for detailed application instructions.
