Clear, Optical Epoxy Potting Compound and Encapsulant
Opti-tec 5020 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 is designed for potting and encapsulation of components where optical clarity, good wetting and low viscosity are important.
Opti-tec 5020-B is a black version with similar properties.
- Opti-tec 5020 is a clear adhesive with a viscosity of 1000 cps.
- Opti-tec 5020 has the resiliency to cope with internal stresses of larger encapsulations. It has a relatively low level of exotherm during cure, and so is safe to use with delicate components.
- Opti-tec 5020 has about a one hour pot life after mixing and cures within 24 hours at room temperature in thick sections.
- Opti-tec 5020 has low viscosity allowing it to fill voids without air entrapment.
- Opti-tec 5020 cures to a high gloss finish, even under high humidity.
- Potting or encapsulation
- Encapsulation of larger components
- Optical assembly, optical filters, LEDs
- Void filling in cables
