Product Name：

Multicomponent copolymerization epoxy silicone oil

Molecular Structure:

R1,R2 : polyether, polyester...

Characters:

Multicomponent copolymerization epoxy silicone oil is epoxy ended,the main chain has polyethenoxy ether,silicone,polyester,acylamino,etc group.It is a linear multicomponent copolymerized silicone intermediates. It can be reacted with amidogen due to the epoxy group.

Multicomponent copolymerization epoxy silicone oil is a new type of intermediates which replaces epoxy terminated silicone oil.It can be used to produce 50-95% content of block silicone oil.

Specifications and Purpose:

We can custom it with the molecular weight 4000-20000.

Advantage:

1. Multicomponent copolymerization epoxy silicone oil gathers silicone,polyether,polyester,acylamino,etc several groups.The users only add the organic amine to get the new structure of block silicone oil.The product has very good stability.

2. Multicomponent copolymerization epoxy silicone oil has the hydrophilic polyether chain,the manufacturers don’t need to use ED series of polyetheramine in the subsequent block copolymerization,that reduces the cost of the block silicone oil.

3. It can reduce greatly the dosage of the solvent in the process of polymerization with organic amine. The solvent dosage is only 5%-20% of the epoxy terminated polyether silicone oil quantity. The reaction product is an even transparent stable high concentration block silicone oil,that improves the application performance of the product and also reduces the discharge of the organic substances,more environmentally friendly.

4. Customers can select the organic amine by themselves or use our company’s compound organic amine.  

5. The manufacturer can produce all kinds of hand feelings of block silicone oil with different molecular weight multicomponent copolymerization epoxy silicone oil.For example,it can be used to produce 50-95% concentration block silicone oil.

6. The quaternary ammonium modification product has better hydrophilicity and stability than common quaternary ammonium salt modified silicone oil

7. It can be used in many other fields besides the textile auxiliary.For example,used in water soluble epoxy resin system to improve the flexibility of the resin and reduce the interior stress.

Packing: 

 190kg/drum,IBC drum

Storage：
