Why choose this product

Formulated for Electronic & Electrical Use

ASI 388 silicone is a moisture-curing, neutral silicone designed for electronic assembly, offering excellent dielectric properties, high resistivity, and chemical resistance. Its non-corrosive system ensures safe sealing of sensitive components, outperforming generic sealants in durability and safety for Indian electronics manufacturing.

Suitable for Sensitive, Confined Environments

This silicone emits no objectionable odors during cure, making it ideal for indoor, confined, or ventilated spaces common in Indian electronics labs and repair shops. Skip if you need a non-odorless, fast-curing product for outdoor or heavy-duty industrial sealing.

How to use
