OPTOLINQ PM-1213 | Two-part silicone potting


Main features
  • High optical transparency
  • Excellent thermal resistance
  • Excellent adhesion to different materials

Product Description

OPTOLINQ PM-1213 is a two-component clear silicone rubber potting specifically designed for the encapsulation and bonding of optoelectronic chip on board (COB) packages. Its high refractive index (1.41) and exceptional transparency minimizes optical interference, making it ideal for high-performance LED packaging applications. 

OPTOLINQ PM-1213 advanced formulation provides excellent light and thermal stability, ensuring long-term performance even under challenging environmental conditions. The high adhesion strength and high elasticity of PM-1213 make it versatile for demanding applications where reliability is crucial.

Pot Life
Pot Life
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed.

It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.

Refractive index
Refractive index
The refractive index determines how much the path of light is bent, or refracted, when entering a material. It is calculated by taking into account the velocity of light in vacuum compared to the velocity of light in the material.

The refractive index calculation can be affected by the wavelength of light and the temperature of the material. Even though it is usually reported on standard wavelengths it is advised to check the TDS for the precise test parameters.

Shelf Life
Shelf Life
Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties.

It differs vastly per product and it is based on temperature and storage conditions.

The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 25°C 6 days
Physical Properties
Viscosity
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in

Mechanical Properties
Hardness
Hardness
Hardness is a dimensionless quantity. There is no direct relationship between measurements in one scale and their equivalent in another scale or another hardness test.

Elongation
Elongation
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
 130 %
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.

Additional Information

Processing Instructions

  • Mix Parts A and B in a 100:100 weight ratio. Ensure that the mixture is uniform and free from streaks or unevenness.

  • Defoam the mixture under vacuum.

  • Typical curing conditions: First cure at 80 °C for 60 min, followed by post cure at 150 °C for 180 min.

 

Precautions

  1. Addition-cure materials may be susceptible to inhibition by certain substances, including organotin and other organometallic compounds, silicone rubber with organotin catalyst, sulfur-containing materials such as polysulfones, amines, urethanes, amine-containing materials, unsaturated hydrocarbon plasticizers, and some solder flux residues. Always exercise caution and conduct thorough compatibility testing when encountering materials or chemicals of concern in your specific application to prevent potential curing issues.

  2. Avoid skin and eye contact. In case of contact, rinse thoroughly with soap (for skin) or clean water (for eyes), and seek medical attention if needed.

  3. Maintain a clean and ventilated workplace, using extraction trunks when necessary.

  4. Wear appropriate protective equipment and minimize direct contact with the human body. Refer to the Safety Data Sheet (SDS) before use.

 

Please note that the provided information is based on available data and typical conditions. For specific applications and detailed test results, refer to the actual test data and conduct appropriate certifications.

 

Cleaning

Uncured silicone can be easily removed using common hydrocarbon solvents, such as acetone or xylene. Polar solvents, including water and alcohols, are not recommended for this application.

 

Storage and Handling

Store in a ventilated, dry, and clean environment below 25 °C. Do not allow moisture to come into contact with these materials. Containers should always remain tightly sealed. For partially filled containers, it is recommended to purge them with dry air or inert gases like nitrogen to maintain product integrity. At proper storage conditions, Part A and B have a shelf life of 6 months.
