Description: JSC-203 is a kind of solid dry powder adhesion promoter. It is easy to weigh, use and disperse. The product is in the state of free flowing dry powder and can be easily mixed and dispersed with the solid resin, pigment and filler in the formula. .

In paint:

1. Can significantly increase the adhesion of the coating to metal, glass, ceramic, polar plastic and other substrates;

Second, enhance the water resistance and boiling resistance of the coating;

3. Enhance the dispersibility and wettability of pigments and fillers;

Fourth, enhance the cross-link density of the coating, thereby enhancing the pencil hardness, scratch resistance and abrasion resistance of the coating, and improving its solvent resistance, acid resistance and alkali resistance.

Physical and chemical properties:

Typical uses

1. Powder coatings for specific substrates

The surface of some substrates such as galvanized sheets, aluminum sheets, glass, ceramics, polar plastics, etc. is often very smooth, and ordinary powder coatings are difficult to attach. JSC-203 can react with the hydroxyl groups on the surface of these substrates to form chemical bonds, which can significantly enhance the powder Paint adhesion.

2. Powder coatings with high requirements on water resistance and boiling resistance

Outdoor products (such as aluminum profiles for construction, aluminum alloy curtain wall panels, transportation facilities, outdoor furniture and garden facilities) and indoor products that work in humid environments (such as household appliances and kitchen appliances such as washing machines, refrigerators, etc.) are water-resistant to the coating The requirements for sex and boiling resistance are becoming more and more stringent. Even powder coatings with good adhesion will blister after soaking in warm water for 24 hours, and will peel off when pulled apart. At this time, you need to use JSC-203 in the formula

3. Anticorrosive powder coating

Pipes, ships and steel bars are exposed to wet and corrosive environments for a long time. JSC-203 can effectively enhance the anti-corrosion performance of powder coatings: First, it is more convenient to combine the pigments, fillers and resins in the coating, and enhance the corrosion resistance of the coating; The second is to close the interface between the coating and the substrate through coupling, prevent the migration and penetration of water molecules along the interface, and reduce the peeling and electrochemical erosion of the coating by the water molecules.

4. Insulating powder coating

JSC-203 helps to enhance the electrical insulation performance of the coating, and the electrical performance in the wet state. Related tests show that the glass fiber epoxy laminate with adhesion is 1×10 6 times the resistivity of the blank control group after boiling for 72 hours .

5. Powder coatings with large fillers

JSC-203 can improve the wettability, dispersibility and compatibility of filler (BaSO4, CaCO3, etc.) and resin, and increase the powdering rate. Using JSC-203 can increase the filling amount of inorganic filler by 20-30%, thereby reducing the production cost.

Method of use: 

Add JSC-203 directly, mix and extrude with other materials. This product has good compatibility with resin and other additives, does not affect the surface properties of powder coatings, does not interfere with color matching, and has no bad smell.

JSC-203 has a wide application range and good reactivity, and has good effects on various powder coatings such as epoxy powder, polyester powder, mixed powder, polyurethane powder, acrylic powder and so on.

Recommended dosage: 0.3-1.5% of the total powder, the specific dosage is determined according to the test.

Storage and validity period: Store in a cool and ventilated room, moisture-proof and waterproof, away from fire and heat sources, please use it as soon as possible after opening the package. It is valid for one year, and expired products can only be used after passing the test.
