Siltech – Silicone Amines for Coatings

Silicone amine polymers are an interesting category of materials within silicone chemistry.
They tend to provide the very best handle and softness to textile substrates.
They are also quite hydrophobic, so are used in applications such as car care.
They can additionally be used as reactive components in resins.

Broadly speaking, there are 5 categories at Siltech, as follows:

1 – Aminoethyl aminopropyl-based, with structure as shown:

“a” and “b” can be varied.  Silamine 2972 and Silamine MUE are good examples within this product group.

2 – Reactive amino-functional prepolymers, with structures as shown below:

There are a multitude of types, and these can be co-reacted into coatings and resins in order to provide flexibility and add impact resistance.

3 – Silicone polyether amines, as shown here:

In this case, the aminoethyl aminopropyl groups are “solubilised” with polyether groups.  For example, Silamine D208 EDA is water-soluble.  These types are also reactive (carbinol functional), and a, b, c, d and e can be varied.

4 – Silicone alkyl amines have alkyl groups in addition to the amine functionality, in order to improve organo-compatibility. Silamine T-97 is one example, and Siltech has made a series of these products.

5 – Fluorosilicone amines are niche, but Silmer NHF Di-H1 is one example, which has pendant fluoro groups and terminal allyl amines.
