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...
By use of silane coupling agent KH550 the modified HBPE (MHBPE) was grafted onto the surface of ultrafine titanium dioxide by amidation reaction. 以硅烷偶联剂KH550为桥梁,利用酰胺化反应将改性的HBPE(记做MHBPE)接枝到超细二氧化钛表面。 General chemical modification methods were given. The general ...
Fig. 14.Silane reaction scheme and working principle. Thedeposition processcan be controlled by different parameters such as pH value, concentration, hydrolysis time and curing temperature. Thehydrolysis reactionrate of the silane coupling agent is limited by the pH value. Lessening the pH value dec...
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 ...
