The KASTAR-3120 Polymers dissolve quickly in standard organic solutions but are almost insoluble in water. Although KASTAR-3120 contains active genes, it can be stably stored in air for several days without catalyst, but special attention should be paid to the presence of water during storage and processing. KASTAR-3120 can be used in accordance with the traditional mixing process. In order to achieve different properties, it can be blended with other polymers. In order to make the product stable during processing or storage, a certain amount of chemical dehydrating agent must be added. We recommend the use of vinyl trimethoxysilane.

Storage and Expiration date

Stored in the original sealer at 5 ° C to 30 ° C, yQL-3120 has a standard life of 6 months from production date. Please refer to the storage advice and expiry date on the package. Beyond this date, Kater silicone no longer guarantees that the product meets the sales targets.
