Product Description

Optically Clear Two-Part Epoxy LED Liquid Encapsulant

OPTOLINQ OLS-1000 is a two-part (Part A & Part B), optically clear epoxy casting compound designed for the encapsulation of LED lamps and displays. It features excellent UV resistance, high optical transmittance, high adhesion to a range of substrates, and good thermal shock resistance. It is geared specifically for applications that will not be exposed to temperatures above 125°C, and where the cost of the encapsulation material is a large percentage of the final part cost. The OLS-1000 has been value-engineered to provide the minimum level of acceptable performance for the absolute lowest cost.

Applications of OLS-1000

The OPTOLINQ OLS-1000 has been used extensively for low-power LED encapsulation, automatic LED casting, and potting of large optoelectronic modules. Each of these applications relies on the high clarity and other optical properties of the OLS-1000 as well as its excellent mechanical properties. The OLS-1000 can be colored and diffused by the addition of specific dye concentrates and diffusant concentrates.

OPTOLINQ Family Series

CAPLINQ OPTOLINQ™ OLS-Series are a family of optically clear (often called “water-white”) liquid encapsulants that are used to encapsulate optical or optoelectronic devices that require both a high level of light transmittance as well as a good level of mechanical protection. Products in this OLS-Series family can be epoxies, silicones or hybrid technologies. They are used extensively for the encapsulation of LED devices, but could be well suited for other applications that require a clear, optical grade encapsulation system.

The OPTOLINQ OLS Series is CAPLINQ’s Opto Liquid System (OLS) series and is made up of several families of products that each have their own unique attributes and application-specific benefits.

Main Applications

  • Low-power LED Encapsulation
  • LED casting
  • Optoelectronic module casting and encapsulation

Product Features & Benefits:

  • Mix Ratio 100:100
  • Temperatures up to 125°C
  • High Refractive Index (1.52)
  • Good sulphur resistance
  • Low viscosity
  • Good degassing properties
  • Lowest material price

Additional Handling Instructions

Preheat Part A to 40°C and then mix in Part B in the required mixing ratio given above. Ideally, the mixture of Part A and B will be done in a vacuum and degassed at 3 torr (400 Pa) for 10-15 minutes. This will ensure that all the entrapped air bubbles are removed after mixing. For best results, ensure that all moisture has been removed from the parts to be encapsulated by preheating them for 1 hour @ 90°C. Also for best results, the encapsulation should be carried out in a vacuum.

Using Additives with OLS-1000

Optolinq OLS-1000 can be mixed with diffusing agents or color pastes to achieve customer-specific purposes.

Recommended quantity (in weight %) of various diffusing agents and color pastes to be used with OLS-1000:

  • OAA1-2 Red Color Paste: 2-5% by weight
  • OAA1-3 Blue Color Paste: 1-3% by weight
  • OAA1-4 Green Color Paste: 2-4% by weight
  • OAA1-D Diffusing Agent: 2-5% by weight

Storage and Handling

OPTOLINQ OLS-1000 is supplied in cans and jars and should be kept in a cool (10°C – 25°C) dry place (40% – 75% humidity) away from direct sunlight or temperature extremes. Part B is particularly sensitive to moisture, so be sure to remove moisture after using and to keep the lid of the container tightly sealed after use.

Temperature Resistance
Temperature resistance is the maximum temperature that the material or product can withstand for a period of time.

The temperatures listed should be considered as guidelines for an operating temperature of about 30 minutes. Typically, the material can withstand much longer times at temperatures about 20°C lower and can withstand much higher temperatures for short, intermittent times.
