These properties are provided as typical properties. Not the product technical index.

Proposed Dosages:

Dosage based upon total formulation, %
IR-8300.05-0.3, in the solvent-free system, can up to 0.5

Addition Methods&Process Technology Instructions:

IR-830 can be added during any production stage, including post-addition.


IR-830 provides a strong reduction in surface tension of paint systems, especially for improving substrate wetting and avoiding cratering. Additionally, surface slip and gloss are increased.

Compared to silicone oils, IR-830 is user-friendly. However, please test the foam stability through experiments before use. Additionally, it is necessary to assess its recoatability and shrinkage cavity tendency.


IR-830 is widely used in solvent-free and solvent-borne coating systems, printing inks, adhesive systems, and ambient-curing plastic systems. It belongs to thermal-stable organo-silicone auxiliaries and will not decompose between 150~230℃. This is different from traditional organic silicon. Thus, surface defect and adhesion reduction will not happen when recoating.

Packing and Storage:

Packed in iron drums of 25 kg or 200 kg net each. The validity period is 12 months in sealed containers. Separation or turbidity may occur at temperatures below 5℃.
