Overview

Organic silicon power adapter waterproof and flame-retardant sealing adhesive, thermal conductive sealing adhesive is commonly two-component, and there are also single component heating curing adhesives. There are several varieties of thermal conductive potting epoxy adhesive, including ordinary thermal conductive, high thermal conductive, high temperature resistant, etc. Different thermal conductive potting epoxy adhesives have significant differences in adhesion to different cavities. The thermal conductivity also varies greatly, and manufacturers can customize it according to their needs.

Product Details

Silicone power adapter waterproof and flame-retardant sealant：

Thermal conductive potting adhesive (HCY) is a low viscosity flame-retardant two-component addition molded organic silicon thermal conductive potting adhesive that can be cured at room temperature or by heating, with the characteristic of faster curing at higher temperatures. It is made by adding thermal conductivity to ordinary silicone or adhesive silicone, and is generally produced by excellent manufacturers. It does not produce any by-products during the curing reaction and can be applied to materials such as PC (Poly carbonate), PP, ABS, PVC, and metal surfaces. Suitable for thermal conductivity, insulation, waterproofing, and flame retardancy of electronic components, with flame retardancy reaching UL94-V0 level. To comply with the EU ROHS directive requirements. The main application areas are the encapsulation of electronic and electrical components, as well as electrical components. It is also used in situations such as temperature sensor encapsulation. The most common thermal conductive sealing silicone is composed of two components (A and B components), including addition or condensation type silicone rubber. Addition type silicone rubber can be deeply sealed without the production of low molecular weight substances during the curing process, with extremely low shrinkage rate and good adhesion to components or sealing cavity walls. The condensation type has a higher shrinkage rate and lower adhesion to cavity components. Single component heat conductive silicone rubber also includes two types: condensation type and addition type. Condensation type generally has good adhesion to the substrate but is only suitable for shallow sealing. Single component heat conductive silicone rubber generally requires low temperature (refrigerator storage) and needs to be cured by heating after sealing. Thermal conductive potting silicone rubber can achieve different thermal conductivity coefficients based on the addition of different thermal conductors. Ordinary ones can reach 0.3-0.8, while high thermal conductivity can reach 4.0 or above. Generally, manufacturers can make specialized adjustments according to their needs.

Silicone power adapter waterproof and flame-retardant sealantUsage

1. Mix and stir evenly in a ratio of A: B=1:1 according to weight before applying glue. Note that in order to ensure the good performance of the product,

Before mixing component A and component B in a 1:1 ratio, they need to be thoroughly stirred before weighing and sampling for proportioning. Then, the prepared rubber material should be stirred evenly before being applied and sealed.

2. The operation time is not only related to the product formula, but also mainly affected by temperature. High temperature will accelerate the curing speed, and the operation time will be correspondingly shortened. Low temperature will slow down the curing speed, and the operation time will be correspondingly prolonged.

3. The ZH908 thermal conductive sealant that has been thoroughly mixed and stirred can be directly poured or poured into the container to be cured. It can be cured at room temperature or by heating. If the sealing height is thick and the appearance requirements for the cured product are high, it can be vacuumed according to the situation to remove the bubbles before sealing.

4. Specific materials, chemicals, curing agents, and plasticizers can hinder the curing of ZH908 thermal conductive sealant (silicone), mainly including organic tin and other organic metal composites containing organic tin catalysts, silicone rubber sulfur, polysulfides, polysulfides, or other sulfur-containing substances such as amines, aminoethyl formate, or unsaturated hydrocarbon plasticizers containing amines. Some flux residues. Note: If there are doubts about whether a certain object or material will cause curing obstruction, it is recommended to conduct small-scale tests to determine its applicability in this application. If there is no phenomenon of non curing or partial non curing in the experiment, it can be used with confidence.

5. The two components should be stored separately in sealed containers, ensuring that they are prepared as needed. The mixed adhesive should be used up in one go to avoid waste.

Introduction to Encapsulated Silicone

Encapsulated silicone, also known as two-component organic silicon additive thermal conductive potting adhesive, belongs to silicone products. A synthetic rubber made by mixing two seasonings together.

characteristic

1、 It has flame retardancy and is rated UL94-HB.

2、 Low viscosity, flowability, and self foaming properties make it convenient to encapsulate complex electronic components, which can be poured into fine details.

3、 Components with detachable sealing can be removed for repair and replacement, and then repaired with this sealant.

4、 The adhesive material can be stored for a long time after mixing at room temperature, but it can quickly cure under heating conditions, which is beneficial for use on automatic production lines.

5、 No shrinkage during curing, with better waterproof, moisture-proof and anti-aging performance.

The characteristics of sealant are not limited to this, but the silicone properties it possesses can also be used in production and daily life. Such as its good acid and alkali resistance, resistance to atmospheric aging, insulation, compression resistance, moisture and shock resistance.
