BQ-4138A / B (high refractive index, SMT adhesive)

Explanation

This product is a component of high refractive index liquid silicone potting materials, mainly used as high refractive plastic patch. With high transmittance, high refractive index, good weather resistance, good flow properties, good heat resistance, longer operating time and so on.

Applications

LED SMD package.

1 Use the proportion: BQ-4138A: 1

BQ-4138B: 4

(2) The A, B, phosphor was mixed to no knots, no lumps, a uniform thin thick homogeneous state (generally requires 5-8 minutes), placed under vacuum

       Deaeration, until no bubbles emerge until the (vacuum degassing process without heating).

3. Degassing is completed, the plastic material poured into the filling plastic syringes. To further drive out the air rubber, plastic material can be installed on the vacuum syringe

       Again discharge bulbs.

4 Glue, should first stand or pedestal preheated 150 ℃ / 0.5H above, to remove moisture inside the stand or base, in order to avoid air bubbles during curing.

5 Curing conditions: 80 ℃ / 1H (short roast) +150 ℃ / 3H (long roast)

Packing A: 0.5Kg / bottle B: 0.5Kg / bottle

Storage conditions Store in a cool dry and ventilated enclosed place (storage temperature -5 ~ 25 ℃, humidity ≤ 65%), waterproof, leak-proof, sunscreen, anti-high temperature, far

Away from sources of ignition.

Shelf life of six months;

Precautions

Applications: 1.BQ-4138A / B using stored process must ensure that no phosphorus (P), sulfur (S), nitrogen (N), the organic tin (Sn), water, polyurethane resin

       Other catalyst poisons, so as to avoid obstruction and deterioration curing (eg: cleaning plastic cup of the solution, oven residues of toxic ingredients, organic acids, etc.).

2 due to BQ-4138A / B with the temperature dependence of the viscosity of particularly large, therefore, recommended operating ambient temperature of 25 ± 2 ℃, avoid discharge bulbs and point-

       Gum problems.

Safety: Be careful using this product before use and the use of safety precautions, please note. Furthermore, it should follow the relevant national or local government regulations Safety Act

       Regulations. (Detailed safety instructions refer to the corresponding MSDS)
