    Methyltris (methylethylketoxime) silane

    (22984-54-9)
    Methyltris(methylethylketoxime)silane is used as a neutral curing agent in silicone sealant formulations. Generally, this silane is used for crosslinking α,ω-silanol polydimethylsiloxanes in the presence of atmospheric moisture. It is often the main crosslinker of choice for oxime silicone sealants and can be used by itself or in combination with other oxime silanes to provide the sealant with targeted properties (such as desired cure rate, adhesion etc).

    Bis[3-(triethoxysilyl)propyl]tetrasulfide

    (40372-72-3)
    When used in rubber compounds, it produces these effects:
    Coupling agent for non-black pigments;
    Cure equilibrium for reversion resistance;
    Curing agent for good heat aging.
    Coupling Agent - With as little as 0.5 to 1.0 phr with clay fillers and 1.0 to 4.0 phr for silica pigments, BIS[3-(TRIETHOXYSILYL)PROPYL]TETRASULFIDE couples the non-black pigment and elastomers resulting in increases in modulus and increase in abrasion resistance.
    Cure Equilibrium - BIS[3-(TRIETHOXYSILYL)PROPYL]TETRASULFIDE has four sulfur atoms positioned in the center. At cure temperatures, these participate with sulfur in producing polysulfidic crosslinks. The BIS[3-(TRIETHOXYSILYL)PROPYL]TETRASULFIDE replaces crosslinks broken during cure, resulting in reversion resistant, and with proper compounding, reversion free compounds. This is known as equilibrium cure. The dynamic flex characteristics, E.G., heat generation and crack growth, are dramatically improved.
    Curing Agent - Removing all sulfur from the compound for NR, SBR, NBR and replacing it with BIS[3-(TRIETHOXYSILYL)PROPYL]TETRASULFIDE and certain thiuram accelerators, produces compounds with excellent heat aging characteristics in addition to the coupling effects. BIS[3-(TRIETHOXYSILYL)PROPYL]TETRASULFIDE is a silane coupling agent that has crosslinking and accelerator activity in rubber compounds. Area of rubber industry where they would be beneficial

    Dcp Cross-Linking Agent

    (80-43-3)
    The production method is derived from the reduction and condensation of cumene hydroperoxide. Cumene hydroperoxide was reduced to benzyl alcohol at 62-65°C with sodium sulfite. Then, in the presence of a perchloric acid catalyst, benzyl alcohol and cumene hydroperoxide are condensed at 42-45°C to obtain a dicumyl peroxide condensation liquid. After washing with 10% sodium hydroxide solution, concentrated by vacuum distillation, and then dissolved in absolute alcohol, crystallized below 0 ℃, filtered and dried to obtain DCP. The content of industrial products is 97%. Raw material consumption (kg/t) cumene hydroperoxide (32-35%) 1500 sodium sulfite 978 perchloric acid 22. Use sodium sulfite to reduce cumene hydroperoxide (CHP) to benzyl alcohol (CA) at 62~65℃ ). Then, in the presence of perchloric acid catalysis, benzyl alcohol and cumene hydroperoxide are condensed at 42-45°C to obtain a dicumyl hydroperoxide condensation liquid. After washing with 10% sodium hydroxide solution, concentrated by vacuum distillation, then dissolved in absolute alcohol, crystallized below 0 ℃, filtered and dried to obtain DCP. The reduction and condensation synthesis reaction formula is as follows"> Natural rubber, synthetic rubber, vulcanizing agent and cross-linking agent for polyethylene resin, not used for vulcanizing butyl rubber. The cross-linking agent of polyethylene used as cable sheath in Japan accounts for 70%, and the other part is used for cross-linking foam material of EVA, rubber vulcanization, curing cross-linking agent of unsaturated polyester, etc. Cross-linked polyethylene as a cable insulation material not only gives polyethylene excellent insulation and processing properties, but also improves heat resistance. 100 parts of polyethylene use 4 parts of this product, DCP can make EVA foam material to form fine and uniform foam, while improving heat resistance and weather resistance. This product is also used as an initiator for polymers. Used as a cross-linking agent for nitrile rubber, neoprene rubber and polystyrene. When used as a free radical suspension polymerization initiator, it can be combined with a reducing agent ferrous salt to form a redox initiator. Mainly used as an initiator for low-temperature polymerization of styrene-butadiene rubber and synthesis of anaerobic rubber. Its initiation rate is 30% to 50% faster than cumene hydroperoxide, but it is faster than t-butyl cumene hydroperoxide and triisopropyl hydroperoxide Benzene is slow. It can also be used as a curing agent for unsaturated polyester and as a cross-linking agent for phenolic butyronitrile adhesives to improve heat resistance and aging resistance.

    The Silane Reagent is a type of organosilicon monomer or small molecule compound used to change or protect the active groups in organics in analysis or organic synthesis. It was originally used in the field of analysis, replacing active hydrogen in organic compounds with silyl groups Atom, the physical properties of its silyl derivatives change, boiling point and so on. Gas chromatography can be used for analysis. Later, in organic synthesis, such as the pharmaceutical industry, a large number of silylating reagents such as hexamethyldisilazane were used to increase the yield of reaction products.
