Product Description
OPTOLINQ LE-EP246D is a two-component, low viscosity epoxy with excellent handling properties, chemical resistance, and high-gloss finish. It is ideal for potting, casting, sealing, encapsulation, and adhesive applications in electronic components, as well as for general industrial uses requiring extended work life.
The hardener of LE-EP246D does not form insoluble, white solids even after being exposed to air. The cured surface remains oil-free while maintaining excellent gloss retention. Additionally, OPTOLINQ LE-EP246D offers excellent electrical insulation properties under high humidity conditions, withstands exposure to a wide range of chemicals and solvents, and complies to RoHS 2011/65/EU Directive.
Applications
- Potting, casting, and encapsulation of electronic components
- General industrial sealing and coating applications
- Adhesive for transparent, chemical-resistant assemblies
- Applications requiring extended work life, chemical resistance, and optical clarity

| 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. | 8 hours | ||||||
| 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. | 1.532 | ||||||

| Glass Transition Temperature (Tg) Glass Transition Temperature (Tg) The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs. | 90 °C | ||||||

| 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. | 10 % | ||||||

| 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 order to better suit an application | 262.5 mPa.s | ||||||
