Product Description

SI8250 is high purity two-component heat curing silicone materials. Primarily designed for the manufacture of optical device modules, and can be used for injection molding an optical lens and an optical wave guide coupling reduces scattering loss. Resistance to environmental pollution, moisture, shock, vibration, etc., Maintain optical properties, mechanical properties and electrical properties in a wide range of temperature, humidity and harsh environmental conditions

.

Key Features

1. High transparency

2. Excellent heat resistance

3. Long-term resistance to UV-A and UV-B

4. No yellowing

5. Fast curing and rapid demold

6. Extremely accurate molding effect

7. Lighter than glass

 

Packing Specification

 

Part A: 0.5kg/Pot, Part B:0.5kg/Pot;

Part A:5kg/Pot, Part B:5kg/Pot.

 

Transport &Storage

When stored at or below 20°C dark and cool place in the original unopened containers, both Part A and Part B have a usable life of 12 months from the date of production..

It’s non-dangerous goods, can be transported as normal chemicals, CAUTION leakage during transport.

 

.Directions for Use

1. The substrate surface should be clean and dry. The substrate can be heated to remove surface moisture. Using naphtha, methyl ethyl ketoxime (MEK) or other suitable solvent to clean surface of the substrate. It should not use the solvent which dissolve or corrode to the substrate, should not use residual solvent.

2. Please keep accurate weigh to a clean glass container and mix thoroughly. When using high speed mixing equipment, heat will generate and the work time will reduce.

3. Under 10mmHg vacuum extrusion bubble. Usually prolapse bubbles before dispensing packaging material.

4. In most cases, the polysiloxane is suitable for working long hours at -45°C to 200°C, the maximum short-term resistant to 350°C, the specific use, it is best to test the actual requirements.

5. Before the uncured material, containing not touch N \ P \ S and other organic matter, cannot touch Sn \ Pb \ Hg \ Bi \ As the ionic compound, etc., cannot touch the acetylene-containing \ active vinyl compound, peroxide cannot touch not touch the water gas and alcohols. These substances will hinder curing material reaches a certain concentration, the specific performance of three phenomena: the flow has been in a state completely cured, and the substrate base surface with thin fluid or in Las state, the contact surface and the substrate smiling bubbles. Fully test before use.

6. Should be cured by heating using a hot air oven ventilation to prevent the accumulation of trace amounts of hydrogen generated in the curing process to produce an explosion hazard.

 

Attention of operation

Keep away from Children

Avoid contact with eyes and skin. If contact with your skin, scrub first with soap water or alcohol, then rinse with water. If contact with your eyes, rinse with plenty of water, and seek medical treatment immediately.

 It is forbidden to build on the surface of the wet substrate.
