SH-VMQ Organic silicone resin

　　SH-VMQ Organic silicone resin

　　一，Performance and Characteristics

　　Methyl vinyl MQ silicone resin is a kind of new organosilicon material with three-dimensional structure composed of Si-O bond.It is a very unique class of silicone polymer polysiloxane compounds,is a compact ball with a bilayer structure.Its structural formula:

　　[(CH3)2(CH2=CH)SiO0.5]a [(CH3)3SiO0.5]b[SiO2]c。

　　[(CH3)2(CH2=CH)SiO0.5]a [(CH3)3SiO0.5]b is M unit,[SiO2]c is Q unit.It has excellent heat resistance, film forming, adhesion, water repellency, aging resistance, UV radiation resistance. Because of the introduction of vinyl group, the modification of silicon-hydrogen addition can be realized. Can be used for silicone pressure-sensitive adhesive, building sealant, organic resin coating as tackifier, mobile phone buttons, epoxy adhesive surface bonding, etc.

　　二、Main technical indexes

　　三、Application

　　1、It can be used as tackifier for Silicone pressure sensitive adhesive

　　2、It is used for the preparation of high-temperature resistant coatings,for the insulation and bonding, sealing of H-class motors.

　　3、It can be used as reinforcing additive in add-molded liquid silicone rubber.The reinforced silicone rubber is colorless and transparent with high mechanical strength.

　　4、It can be used to produce all kinds of waterproof paint.It is the ideal material for daily chemical industry such as lipstick and so on.

　　5、It can be used as release agent of various materials.

　　6、It can be added into the defoamer as a basic material to improve the ability of defoaming and anti-foaming.

　　四、Packaging and storage

　　Form of supply: powder type, solution type

　　Package specification: 20kgs buckets or 200kgs lining steel drums

　　Storage life: Sealed at room temperature.The storage life of solution type is half one year,the powder is one year.The storage time is longer than the best use period marked by the label does not mean that the product cannot continue to be used. But in this case, retesting is needed.
