- Low effect on brightness
- Soft and consistent luminosity
Product Description
ODF-10 Diffusing agent is a light diffusing agent commonly used in LED applications. The main function of a diffusing agent is to evenly diffuse the light emitted by the LED chip in the resin. This makes products using this material to emit a soft and consistent luminosity.
ODF-10 diffusing agent is a low viscosity (±20,000 mPas) milky white liquid that has a small effect on the LED's brightness. It is suitable for the production of various luminous products such as LED Lamps and LED Displays. ODF-10 has low viscosity and good compatibility with A/B resins, so it can be used directly.
ODF Type S offers a stronger diffusing effect than ODF-10. Both products use the same dispersant materials. Amounts added to resin can be adjusted to match the required diffusion.

| 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 | 19,800 mPa.s |

Processing Instructions
Stir and preheat the agent at 70~80°C.
Directly add the diffusing agent to A/B resin that will be used and stir uniformly.
Defoam the mixture for 5 minutes and use the mixture within pot life of the resin used.
Curing conditions of the the resin used should be followed.
Precautions
Do not preheat for a long time to avoid sedimentation and difficulty in stirring.
A small amount of resin will float out after long-term storage of this product. This is a normal phenomenon. Please stir well before use.
Storage and Handling
Store in a ventilated, dry, and clean environment below 25°C and 70% humidity. Keep away from fire and heat sources. It is strictly forbidden to store in outdoor environments. At proper storage conditions, the product has a shelf life of 6 months.
