1、Brief introduction of products ：
     This product is a kind of special rubber that can be sulphurated under the room temperature. Its chemical compositions are with gathering two methyl silicons oxygen and alkane of the hydroxyl, the chemical structural formula is:

2、Quality index ：(HG2-1494-83)：

3、Performance and use
    Product this have lying between electric performance fine after sulphurating, insulating able to bear electric arc corona , able to bear oxygen and able to bear atmosphere wear out excellentlying, chemistry is steady. Can be - using in 60 - +180 degrees Centigrade of temperature ranges. It is convenient and operating simple and easily that the room temperature sulphurates one of the characteristics of the silicon and lies in shaping. So, this product can be used in the insulation of such electronic elements as radio , electron tube instrument , semiconductor ,etc. and association one , take precautions against earthquakes , sealing dampproofly extensively. Can make die material and mould material applied to resin solidification shaping .

4、Operation method (room temperature sulphurates the craft ) ：
    Fetch 0 for 100 pieces of glue and catalyst (two cube base tin of silicic acid of daily February ) before using. 5-5 copy,it pay pharmaceutical I (daily for second silicic acid ester not straight,) mix and not even 1-10 copy fully,namely suitable for by flooding, casting or applying paint with a brush not spending. Pass the preliminary solidification of 2-4 hour , the basic stability after 3 days. Explanation 、：
    l、Catalyst , pay consumption , I of pharmaceutical, to sulphurate glue to be performance influence big, but to sulphurate speed of course have obvious function . Consumption its heavy to sulphurate speed to be fast.
    2、Put catalyst into and pay sizing material , I of pharmaceutical , under the general room temperature , should use up within 1-2 hours . So need it according to consumption , use and mix at the same time at the same time.
    3、The work piece surface that is exposed to with the sizing material must be through purification (wipe clean with the acetone or the benzene, it is and then it dry,) otherwise can't influence there aren't glue and work piece ,scribble not lasting pharmaceutical surface in case of necessity (for instance: Methyl three acetyl oxygen there is on two chlorine methane for solution 10% in silane base ,) with increasing not for intensity of forminging.
    4、If find while mixing and compounding the sizing material that there are bubbles that are sneaked into, release the vacuum to get rid of; It find it take place for a long time surface glue (the too the following to sulphurate ,),the getting getting getting more straight a more bit more more slightly second silicic acid ester can have overcome when not compounding ; Find the deep department difficult to sulphurate after the strong encapsulation, even does not sulphurate for a long time, can be while compounding, join 0 of every 100 copies of sizing material . Water of 4 can be solved.
    5、Is it pay I straight silicic acid second very easy to become damp and rotten ester that pharmaceutical spend to make , should be airtight to store, if give play to, namely unsuitable to use. Two cube base tin of silicic acid will condense when the temperature is lower in February when use as catalyst , with before must have water bath it is warm the hot to dissolve.
    6、The room temperature of different types sulphurates the silicon rubber and can try one's utmost and mix each other in wanton proportion , performance of the material by regulating construction viscidity and combing taking.

5、 Packaging and storing and transport ：
    1, This product with clean , antirusting the container splendid attire dry. Packing instructions is sealed and does not leak . (pack the size and can be made according to the need of user).
     2, This product should be put in the shady and cool dry place in storing , transportation, prevent being exposed to the sun and rain.
     3, It was three years since this product stored one effectively.
