/ Two-component condensation-type potting adhesive

Two-component condensation-type potting adhesive

Two-component condensation-type potting adhesive consists of Part A (base adhesive) and Part B (curing agent), which are mixed evenly in a certain proportion before use.

Product Description

Condensation Type

Refers to its curing mechanism. During the curing process, small molecules such as ethanol and acetone are released, resulting in slight shrinkage and odor.

Core Characteristics

It "releases" small molecules during the curing process. This stands in sharp contrast to "addition-type" silicone, which releases nothing during curing, and is also the key distinguishing point when choosing between the two. It has good adhesion, bonding firmly to metals and most plastics without the need for a primer, and has strong anti-poisoning capability, making it less susceptible to failure from contact with sulfur, amines, and other substances. It also has high tolerance for temperature and humidity, can cure at room temperature, and cures quickly at depth;

?Typical Application Scenarios

??Power Supply Industry: Potting of LED driver power supplies, switching power supplies, and adapters, with firm adhesion to components and housings.

??Automotive Electronics: Ignition coils, regulators, sensors, etc., where the environment is complex but the requirements for anti-poisoning resistance are high.

??General Electronic Components: Insulation protection for connectors, relays, and coils.

??New Energy Sector: Charging piles, photovoltaic junction boxes, etc.

Conformal coating

Conformal coating is a special protective coating applied to the surface of printed circuit boards (PCBs) and components. Its core function is to form a transparent or translucent thin film on the surface of the circuit board, thereby providing "three-proof" protection for electronic assemblies. This thin film can effectively resist moisture condensation, acid, alkali, and salt corrosion, fungal growth, as well as a certain degree of dust contamination and chemical erosion, greatly improving the reliability and service life of electronic equipment in harsh environments.

Thermal conductive silicone grease

Thermal conductive silicone grease is a paste-like thermal interface material made by grinding and mixing specialty silicone oil as the base oil with high-thermal-conductivity, high-temperature-resistant inorganic fillers. Its basic design logic is not to rely on itself to become the main heat conduction body, but rather to use its soft paste form, under assembly pressure, to fully fill the microscopic depressions and gaps invisible to the naked eye between the heat-generating component and the heat sink, squeezing out the air, whose thermal conductivity is only about 0.026 W/(m·K), and establishing an efficient heat transfer path through the material's own thermal conductivity, thereby greatly reducing the interfacial contact thermal resistance.

Silicone gel

Silicone gel is a very unique organosilicon material. After cross-linking and curing, it forms a quasi-solid gel that is softer than ordinary silicone and has a naturally tacky surface. You can think of it as a substance between jelly and modeling clay, and after curing it can even self-repair. In terms of chemical composition, it is usually also composed of two-component addition-cure silicone, A and B, with no small molecule release during curing and extremely low volume shrinkage. Its most core characteristic lies in its extremely low cross-link density.

Two-component addition-cure potting compound

Two-component addition-cure potting adhesive is a silicone potting material composed of two liquid components, A and B, which cure after being mixed in proportion.
