ANDISIL VQM 乙烯基MQ 树脂混合物
产品概述
ANDISIL VQM产品是一种固化剂,当它加到硅氧烷弹性体,能使其固化,并改善其
机械性能。
乙烯基功能硅氧烷聚合物(ANDISIL VS)的固化机理是:铂催化剂与含有SiH基团的硅氧烷交联剂进行加成反应。由于没加添加物的RTV 的机械性能很低,因此,在适当添加一些填料如: 碳黑、气相白碳黑、或沉淀白炭黑后性能会有改善,配方师们熟知用其它的一些改性有机硅作填料。
ANDISIL VQM 系列产品是由乙烯基功能的硅氧烷聚合物及乙烯基功能的MQ 树脂组成的产品,这系列产品适用于不添加填料的配方,有良好的机械性能的透明体系,这类产品同样能进一步改善填料配方的的机械性能。

description
Andisil VQM Products are additives for the improvement of mechanical properties of addition cured silicone elastomers. The curing mechanism of vinylfunctional silicone polymers (Andisil VS) is a platinum catalyzed addition reaction with silicone crosslinkers containing silicon-hydride groups.
The mechanical properties of the unfilled RTV are rather poor.Therefore the properties are improved
with the addition of appropriate fillers i.e. carbon black, fumed or precipitated silica and other fillers
well known to formulators with expertise in compounding silicones.
Andisil VQM Products are comprised of vinyl-functional silicone polymers and vinyl-functional QM-
resins.The product group is beneficial in formulating filler free, transparent systems which require
good mechanical properties.The products will also enhance improvement of mechanical properties of
filled formulations.
storage & shelf life
The shelf life, when the container is stored unopened and under proper conditions, is expected
to be a minimum of five years from the date of manufacture.
packaging & handling
Andisil VQM is available in a 440 pound net weight container.
