Product Description

I. Introduction: LD-800A / B series light-emitting diode package with epoxy resin (used for high-end LED package, the full import of raw materials), has a high light transmittance, excellent craftsmanship and electrical and physical parameters for high ideal water through the pipe material, the following features:

1. Low viscosity, degassing performance;

2. Early reaction smooth, low thermal shrinkage stress, high reliability package products;

3. Excellent transmittance of encapsulated products.

4. To add without outside Silicon spraying release agents, mold strip.

Second, it is recommended that the use of technology:

Mixing ratio (weight ratio) 100:100

Time (40 ° C, 35g hrs)> 3.5

The curing conditions (℃ / hrs) 130 ℃ / 30 ~ 40min demolding 100 ~ 120 ℃ / 4 ~ 5h aging.

1 A material use before preheated to 40 ~ 50 ℃, and then added in proportion to the B material, mixing until fully homogeneous.

2 3 toor/40 ℃ mixture of (A + B) vacuum degassing, to see the level drops to 10 to 15 minutes to stop the deaeration.

3 is potting of the device to be pre-baked at a temperature of 70 ~ 90 ℃ 1 hour to tide.

4 recommended under vacuum Epoxy potting.

5 such as the use of DF-090 light-diffusing agent to increase the amount of material B, increasing the amount of half of the amount of DF-090.

6 such as the amount of use creams to increase the amount of material B, and to increase the amount and add Segao.

Three purposes: LED and other electronic devices for high transmittance package.

Fourth, after the curing characteristics:

Hardness (25 ℃, Shore-D)> 88

Volume resistivity (25 ℃, Ω • cm)> 1015

Surface resistance (25 ℃, Ω)> 1014

Dielectric strength (25 ℃, kV / mm)> 23

Linear expansion coefficient (1 / ℃) <6.0 × 10-5

Absorbent (100 ℃ / 1h,%) <0.35

Tg values (° C)> 125

Transmittance (%)> 96

, Storage, transportation and considerations:

1. Such products are non-dangerous goods, as a general chemical storage, product storage period to see the package label.

2. B material is easy to absorb moisture and air, be sure to immediately tightly after use.

3. Curing temperature over 130 ℃ yellowing may occur, it may be more difficult to mold release time is too long.

Sixth, packaging specifications:

Packaging 6KG plastic barrel, barrel side company label.
