Adhesion promoter JSC-2306
The adhesion promoter JSC-2306 belongs to a new type of silane adhesion promoter, which has multiple complex silane structures in its molecule. And they have more active groups on a molecule than ordinary silane coupling agents. Therefore, this product can form a higher cross-link density on the surface of inorganic materials; at the same time, the silicon hydroxyl formed by the reaction of this product is more acidic than the silicon hydroxyl formed by ordinary silane coupling agents, so it can be compared with metals and inorganic materials. The hydroxyl groups on the surface form stronger covalent bonds and are not easily hydrolyzed.
The application of adhesion promoter JSC-2306 includes:
1. Environmentally-friendly surface treatment liquid without phosphorus and heavy metals, replacing traditional phosphating and passivation processes.
2. The cross-linking agent in the adhesive and sealant provides moisture curing function and improves the adhesion to the substrate.
Packing: 25kg plastic drum.
Storage conditions and shelf life: Store indoors in a dark place, keep ventilated, cool and dry. Make sure the lid is well sealed and can effectively isolate the air. The shelf life of the original packaged products is one year, and expired products can only be used after passing the test.
Adhesion promoter JSC-2308
Typical physical properties:
| index | JSC-2309 | JSC-2308 |

Product characteristics and uses: The
silane coupling agents JSC-2308 and JSC-2309 belong to a new type of silane coupling agent, which has multiple silane structures in the same molecular structure, and they have more than one silane coupling agent on one molecule Alkoxy. Therefore, KH-2308 and KH-2309 can form a higher cross-linking density on the surface of inorganic materials; at the same time, the silanol formed after hydrolysis of this product is more acidic than the silanol formed by ordinary silane coupling agents, so It can form a stronger covalent bond with the hydroxyl group on the surface of metal and inorganic materials, and is not easy to hydrolyze.
The specific uses of silane coupling agents JSC-2308 and JSC-2309 include:
1. Environmentally friendly phosphorus-free and heavy metal-free surface treatment liquid, which replaces traditional phosphating and passivation processes.
2. The cross-linking agent in the adhesive and sealant provides moisture curing function and improves the adhesion to the substrate.
