Description

Opti-tec 5020-1 is a clear, two component, low viscosity optical epoxy which will cure in thick sections at room temperature. In thin sections, it is clear and transparent. In thicker sections, it can take a yellow or straw tint. Opti-tec 5020-1 is designed for potting and encapsulation of components where optical clarity, good wetting and low viscosity are important.

Opti-tec 5020-1-B is a black version with similar properties. See Specifications tab for details.

Features & Benefits

  • Available in clear or black versions
  • Degree of flexibility which reduces internal stresses
  • Relatively low level of exotherm during cure making it safe to use with delicate components
  • One hour pot life after mixing and cures within 24 hours at room temperature in thick sections
  • Low viscosity allowing it to fill voids without air entrapment
  • High gloss finish even when cured under high humidity
  • Available in easy-to-use TwinPacks or bulk

Applications

  • Potting or encapsulation
  • Encapsulation of larger components
  • Optical assembly, optical filters, LEDs
  • Optoelectronics
  • Void filling in cables

Specifications

Part number change: as of version 7.0, November 2018, the part number of this product changed from Opti-tec 5020 to Opti-tec 5020-1 and Opti-tec 5020-B to Optic-tec 5020-1-B. This is due to an unavoidable change in a formulation component. This change does not affect the product data sheet specifications. Our tests have shown very similar performance to the previous version.

For optimal results, store away from strong alkalis, oxidising materials, acids, amines and oxidising agents. Prevent storage where formation of sparks or static electricity could be present. Keep only in the original container. Keep container tightly closed and upright, in a cool, well-ventilated place. Protect containers from damage. Bund storage facilities to prevent soil and water pollution in the event of spillage. The storage area floor should be leak-tight, jointless and not absorbent.
