Epoxy polyether silicone oil IOTA-EO Series
The terminal epoxy polyether silicone oil is a
double-active silicone epoxy resin intermediate having a polysiloxane segment
with an epoxy group and a polyoxyethylene ether segment at both ends and a
linear polysiloxane segment in the middle. Because it has an epoxy group, it
can be cured with an amine-based curing agent, and is widely used as an
additive for epoxy resin. It is also an important intermediate for the
synthesis of block silicone oil by replacing the epoxy resin.

Features and advantages:
1. The novel intermediate of silicone multi-copolymer
block silicone oil can completely replace the current end-epoxy silicone oil
for the synthesis of block silicone oil;
2. The end epoxy polyether silicone oil introduces a
hydrophilic polyether segment in the structure. In the subsequent block
polymerization, it is not necessary to use the ED series polyether amine, and
only the D series polyether amine and fat are used. Amines, alcoholamines and
other low-cost organic amines can be used to synthesize block silicone oils,
effectively reducing the raw material cost of block silicone oils;
3. In the process of polymerization with organic amine,
the amount of organic solvent can be greatly reduced. The amount of solvent can
be reacted only by 5%-20% of the mass of epoxy polyether silicone oil, and the
reaction is uniform and stable. The high content of block silicone oil greatly
improves the application performance of the product on the one hand, and
effectively reduces the emission of organic matter on the other hand;
4, the end epoxy polyether silicone oil and organic amine
have good compatibility, in a small amount of solvent or solvent-free
conditions can be effectively carried out homogeneous reaction, the reaction is
more complete and thorough, thus ensuring the quality of the finished product
is more stable;
5, using different molecular weight end epoxy polyether
silicone oil can synthesize a variety of hand-style block silicone oil;
6. The quaternized modified product is better in
hydrophilicity and stability than the ordinary quaternary ammonium salt
modified silicone oil;
7. It can be applied to water-soluble epoxy resin systems
to improve the flexibility and reduce internal stress of the resin.
