NEW REACTION PRODUCT FOR SILANE COUPLING AGENTPROBLEM TO BE SOLVED: To provide a new reaction product for a silane coupling agent by which an improved adhesiveness of an inorganic material to an organic one and good storage stability can be obtained in the use for a surface treating agent, a...
Since the silane-coupling agent has a super-hydrophilic chain, after the reaction, such kind of chain would go towards to the outside surface of the glass substrate and make the surface super-hydrophilic.Previous article in issue Next article in issue Keywords Super-hydrophilic double layers ...
, silane hydrolysis into silanol first, then the silicon alcohol-based and inorganic filler surface dehydration reaction. The silane coupling agent directly added to the adhesive composition, as the matrix resin for the amount of general amount of 1 ~ 5%. After the glue by molecular diffusion ...
A series of benzoyl thiourea silane coupling agents were synthesized from substituted benzoic acid through chloridiza tion, isothiocyanidation, and then reaction with APTES. 以取代苯甲酸为原料,经过氯化,异硫氰酸酯化,再与氨丙基三乙氧基硅烷作用,合成了9种未见报道的酰基硫脲类硅烷偶联剂。 3. The ...
Inorganic-organic copolymer using polyvinylalcohol-silane coupling agent and preparation method thereof Disclosed are inorganic-organic copolymers and their preparation using polyvinylalcohol-silane coupling agents. The inorganic-organic copolymers can be prepared through the reaction of silane-coupling agents co...
atom and accelerates the curing reaction, [...] wacker.com wacker.com 在这种情况下,分子桥处于与硅烷组分的硅原子相对的α-位置,有助于加快固化反应速度,即便没有锡催化剂,整个反应也能非常快速地进行,”瓦克有机硅大客 户经理Michael Graw博士解释道。
This is done to allow the silane the opportunity to migrate to and react with the mineral surface before the other ingredients have the opportunity to interfere with this reaction. Uses of Silane Coupling Agents in Silica Treatment Silica reinforcement of rubber provides unique physical properties ...
2) silane coupling agent KH570 偶联剂KH570 1. Ehylene propylene diene monomer (EPDM)/ fibrillar silicate (FS) nanocomposites and EPDM/FS/PA-66 micro-short fibers were successfully prepared by mechanically blending EPDM with FS which was modified by the silane coupling agent KH570 and PA-66 ...
add 115 g of ethylenediamine dropwise, and finish the dripping in 0.5 hours. Then continue the reaction for 1.5 to 2 hours, control the temperature at 110°C. After the reaction is completed, cool to room temperature, pour out the upper liquid, and obtain the silane coupling agent KH590 ...
In the presence of water, the alkoxy group of the silane coupling agent KH-570 is hydrolyzed to form a reactive silanol group, and at the same time, the hydrolysis reaction by-product methanol is released. This silanol group reacts with a variety of inorganic materials (substrates or pigments...
