Product Description

Optically Clear One-Part Hybrid LED Liquid Encapsulant

OLS-7000 is a one-part, optically clear hybrid 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 was designed specifically to be a silicone-replacement material in mid-power LED applications where silicone is too expensive and does not offer the all the mechanical performance benefits of this hybrid system. It can be used in applications that operature continuously at 125°C without yellowing or losing optical transmittance. It is a one-part encapsulation solution which makes it incredibly easy to use and to automate.

Applications of OLS-7000

The OPTOLINQ OLS-7000 has been tested extensively in mid-power LED encapsulation that previously used a more expensive silicone. Each of these applications relies on the high clarity and other otpical properties of the OLS-7000 as well as its excellent mechanical properties. The OLS-7000 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

  • Mid-power LED Encapsulation
  • UV-LED encapsulation
  • Automotive sensor applications

Product Features & Benefits:

  • No mixing – one part
  • Temperatures up to 125°C
  • High Refractive Index (1.52)
  • Not tacky after cure
  • Excellent sulphur resistance

Additional Handling Instructions

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-7000

Optolinq OLS-7000 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-7000:

  • 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-7000 is supplied in plastic jars needs to be kept in a freezer at –20°C.

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.
