    IOTA OPSZ 9150K can be soluble in polar and non-polar solvents, such as such as alkane, ether, ketone and esters, can’t be diluted with alcohol ether solvents, such as diethylene glycol dimethyl ether, diethylene glycol dibutyl ether, tetraethylene glycol butyl ether.

    IOTA OPSZ 9150K also be diluted with some resins, such as epoxy silicone resin, silicone resin. That can shorten the curing time, and improve the hardness of the resin.


    1. IOTA OPSZ 9150K should be used in a dry, ventilated place with protective measures(gloves, masks) .

    2. Avoilding fire, moisture and water.

    3. Seal the product promptly after use.

    4. Adding nitrogen for protection after use in humid environment.
