Silicone Gel for addition molding
Abstract: JTF-305 Silicone

First, use:

JTF-305 SiliconeMainly used in LED and other electronic components insulation seal, impact protection, waterproof and moisture-proof. After curing with high transparency, high hardness, high-strength, high heat dissipation, low shrinkage, good thermal stability, water in the light does not fog and never yellowing and so on.

function and characteristics


Second, JTF-305 silicone potting glue is mainly used for electronic components such as LED insulation seal, impact protection, waterproof and moisture-proof, and its characteristics are as follows:

1, curing conditions: can be cured at room temperature, can also be heated to cure, with the higher the temperature of curing the faster the characteristics;

2, simple and convenient operation: can choose artificial sizing or mechanical sizing;

3, it has excellent waterproof, can protect the LED and other electronic components are not water immersion, and long-term water in the light does not fog;

4, with excellent heat dissipation, can ensure that the chip in the use of the process will not be due to excessive temperature and affect the service life;

5, with excellent transmittance and refractive index, can minimize the light decay of the light source;

6, with excellent electrical characteristics: excellent insulation performance, heat conduction, heat dissipation, earthquake resistance, corona, leakage-proof and durable chemical media performance, so for electronics, electrical appliances and other products can provide protection, sealing and insulation functions;

7, high and low temperature performance: resistance to high and low temperature, anti-aging good。 After curing in a very wide temperature range ( -40~220℃) to maintain the rubber shells;

8, flexible plastic film: curing process does not shrink, the formation of a good toughness after curing elastomer, absorbing vibration and shock, good impact resistance, with good and cushioning effect, electronic, electrical appliances provide excellent shock and reliability of shock resistance;

9, weather resistance is strong: Anti-ultraviolet, anti-aging, anti-ozone, moisture, waterproof, salt spray, mold, etc., can work in the harsh natural environment.

Technical Specifications


Third, the use of methods:

1, the glue, the JTF-305 adds the molding organic silica gel All is two parts liquid, the use of two parts in accordance with 1:1 of the proportion of mixing, and mixing equipment to fully stir (be sure to ensure that two parts mixed evenly), note: Must ensure that the mixing rod and the container cleaning (not with the rest of the glue contact);

2, vacuum, after the glue will be placed in the bubble-blowing device for bubble treatment, because the silica gel molecular tension is small, so in the vacuum when the bubble is very easy to accumulate, you can see a lot of bubbles very fierce platoon out。 So in order to avoid the waste of glue, in the vacuum, as many times as possible in the discharge valve place gas;

3, after the elimination of bubbles, you can transfer glue into professional potting equipment for drip irrigation;

4, room temperature or heating curing can be。 The curing speed of the glue and curing temperature have a great relationship, at room temperature under the general need to 4-6 curing, 80-100 ℃ under only 20-30 minutes of curing。


Four, security:

1, this series products for pure silicone products, does not contain any harmful substances, is environmentally friendly products, even if the human body direct contact will not have any adverse reactions;

2, this series of products is not flammable product, will not produce volatile substances, no risk of explosion;

3, this series of products in the curing process will not produce any harmful substances, the environment and no harm to the human body.


Five, Attention matters:

1. JTF-305 Plus SiliconeNo contact with incomplete solidification of condensed silica gel, containing nitrogen, phosphorus, sulfur, acetylene, poly vinyl, peroxide and lead, tin, mercury and other metal compounds, to avoid the catalyst poisoning, affect the curing effect;

2, this glue can not be mixed with other glue;

3, two parts of the mix should be as far as possible to ensure a uniform mixing;

4, should be as far as possible to discharge bubble treatment;

5, has been equipped with good glue must be in the operating time to avoid unnecessary waste;

6, unused glue must be sealed to save the storage conditions at room temperature in a cool place to save the best;

7, this product should try to avoid long-term contact with washing board water, days that water and other organic solvents, such as strong acid and alkali;

8, because this product is chemical products, your specific production process is not the Division I can control, so before using the sample, suitable, please rest assured use.
