化学名称 　　γ―甲基丙烯酰氧基丙基三甲氧基硅烷 　　

化学结构式

　　产品性质 　　

本品为甲基丙烯酰氧基官能团硅烷,外观为无色或微黄透明液体,溶于丙酮、苯、yimi、silvhuatan，与水反应。沸点为255℃,密度p25"g/m1：1.040,折光率nd25:1.429,闪点：88℃，含量为≥97% 　

　用途及注意事项 　　

1、主要用于不饱和聚脂树脂,也可用于聚氨脂、聚丁烯、聚丙烯、聚乙烯和三元乙丙橡胶。用于玻璃纤维浸润,其主要配方为：偶联剂、抗静电剂、成膜剂、润滑剂、软水等组份,ydh-570在ph 3.5-4酸化水中水解，在浸润剂中，偶联剂浓度为0.3%-0.6% ，也可根据需要与kh-550或kh-560配制成混合型偶联剂使用。在电线电缆行业，用该偶联剂处理陶土填充过氧化物交联的epdm体系，改善了消耗因子及比电感容抗。　

2、用于白炭黑、滑石、粘土、云母、陶土、高岭土等无机填料的表面处理,以提高对无机材料的粘结力，增加抗水性，降低固化温度。与醋酸乙烯和丙烯酸或甲基丙烯酸单体共聚，这些聚合物广泛用于涂料、胶粘剂和密封剂中，提供优异的粘合力和耐久性。

3、本品遇水水解缩聚成硅醇并受温度、ph值、浓度的影响。避光避湿保存。在25℃以下,以不超过三个月为宜。

硅烷偶联剂kh570必须密封储存，在湿气和热的作用下会发生聚合反应。对皮肤和眼睛有轻微的刺激性，因此使用时要有防护装置。

本品采用5kg塑料桶包装，一箱4桶，共20公斤。其他规格需预定。

product properties

this product is methacryloyl oxygen radicals functional group silane, appearance colorless or light yellow transparent liquid, soluble in acetone, benzene, ether and carbon tetrachloride, reaction with water. boiling point for 255 ℃, density do "g/m1:1.040, the refractive indexes, nd25:1.429 and flash point: 88 ℃, content of p 97%

purpose and the matters needing attention

1, mainly used in unsaturated polyester resin, can also be used to get together ammoniac fat, polybutylene, polypropylene and polyethylene and epdm. used for glass fiber infiltrates, and its main recipe for: coupling agent and antistatic agent, into pellicle, lubricants, water softener, etc ydh - 570 m.p., in ph 3.5 to 4 acidification water in infiltration agent hydrolysis, concentration, coupling agent for 0.3% - 0.6 percent, can also according to need and kh - 550 or kh - 560 made into mixed coupling agent use. in electrical wire and cable industry, with this coupling agent handling argil filling the peroxide crosslinking, improved the consumption of epdm system than inductance rongkang elements and.

2, used for white carbon black, talc, clay, mica, clay, kaolin and other inorganic packing surface treatment of inorganic material, in order to improve the rapping, increase water resistance, reduce curing temperature. and acetate and acrylic or methylacrylic acid monomer copolymerization, these polymer widely used in coatings, adhesives and sealants, provide excellent bonding strength and durability.

3, this product in water into silicon alcohol and hydrolysis polycondensation by temperature, ph value, the concentration of influence. avoid light avoid wet preservation. at 25 ℃ below, with no more than three months advisable.

silane coupling agent shall be sealed storage, kh570 in moisture and hot under the action of polymerization will happen. on skin and eyes have mild irritation, so when used to have protection device.

this article adopts the 5kg packed in plastic drum, a box of four barrels, total 20 kilograms. other specifications need reservation.
