OPTOLINQ OLS-1211 is a two-component (Part A & Part B), low halogen, optically clear epoxy casting compound designed for the encapsulation of LED lamps and displays. Part A is an epoxy resin while part B is primarily a modified curing agent.
OPTOLINQ OLS-1211 offers excellent bonding properties to a wide range of substrates and good resistance against heat aging, cold and thermal shock. Additionally, this epoxy encapsulant features high transmittance and low light decay. It has much better UV resistance and antiblue properties than OLS1000.
OPTOLINQ OLS-1211 has been developed for applications that will not be exposed to temperatures above 125°C. It has been used extensively for low-power LED encapsulation, automatic LED casting, and potting of large optoelectronic modules. It can be colored and diffused by the addition of specific dye and diffusing concentrates.
We recommend to process the product in a clean room at room temperature with a relative humidity lower than 35%.
It is advised to cure in two stages to reduce thermal stress.
Optolinq OLS-1211 can be mixed with diffusing agents or color pastes to achieve customer-specific purposes.
Recommended quantity of various diffusing agents and color pastes:
For example, ODF would be 100 : 100 : 3~5 for LED lamps
OPTOLINQ OLS-1211 is supplied in 5Kg cans and should be kept in a cool and dry place (40% – 75% humidity) away from direct sunlight or temperature extremes. It should not contact any acid and alkali substances. Consult the Safety data sheet for the handling of this product
