Product Description

Optically Clear Two-Part Dimethyl Silicone LED Liquid Encapsulant

OPTOLINQ OLS-3263 is a two-part (Part A & Part B), optically clear dimethyl silicone designed for the encapsulation of mid- and high-power LEDs. It features a very good heat resistance, high optical transmittance and excellent resistance to both UV and heat resistance in applications as high as 170°C. Dimethyl-type silicones are known to have an even higher optical transmittance and wide processing windows. It also has a high level of adhesion to a wide-range of metals, silicones and plastics and to PPA in particular. OLS-3263 can be dispensed from standard dispensing equipment or can also be compression molded using compression mold equipment.

Applications of OLS-3263

The OPTOLINQ OLS-3263 has been specially designed for mid- and high-power LED devices. These LED devices are those often used in applications that will see higher temperatures such as automotive lighting, industrial baylights used in warehouses as well as for street lighting and high-power data projectors or beamers that require high powered light to be emitted over longer distances. It can mixed with phosphor for die-level color conversion.

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.

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-3263

Optolinq OLS-3263 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-3263:

  • 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-3263 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.
