It offers exceptional dielectric properties, waterproof protection, and resistance to extreme temperatures, ozone, and UV exposure. Its odorless curing process and non-corrosive formula make it ideal for sensitive metals and confined workspaces, ensuring reliable, long-term insulation and sealing. ## Description ASI 388 electronic grade silicone is a one-part, moisture- curing RTV (room temperature vulcanizing) silicone sealant/adhesive that is non-slump and cures to form a tough, permanently flexible rubber. The non-corrosive curing system of ASI 388 electronic grade silicone makes it ideally suited for protecting, sealing and insulating corrosion-sensitive electronic and electrical materials such as copper, brass, silver, etc. ASI 388 has been specifically formulated for use in electrical/electronic production and assembly because it: -has good dielectric properties -has high surface resistivity -resists electrical tracking -repels water to protect electrical properties ASI 388 electronic grade silicone is a neutral-cure silicone that emits no objectionable odors during cure and is ideally suited for use in confined areas. However, adequate ventilation should be provided when ASI 388 is used in large-scale production. ASI 388 is a 100% silicone and has excellent resistance to: -ozone -UV -airborne chemicals -temperature changes from -57 C to +204°C (-70°F to +400°F) ## Features - The non-corrosive curing system of this electronic grade silicone makes it ideally suited for protecting, sealing and insulating corrosion-sensitive electronic and electrical materials such as copper, brass, silver, etc - This electronic grade silicone is a neutral-cure silicone that emits no objectionable odors during cure and is ideally suited for use in confined areas; However, adequate ventilation should be provided when used in large-scale production - Specifically formulated for use in electrical/electronic production and assembly ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0063U2RT8 | | Best Sellers Rank | #8,106 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #33 in Silicone Adhesives | | Brand | ASI | | Brand Name | ASI | | Color | Clear,Silver | | Customer Reviews | 4.6 out of 5 stars 673 Reviews | | Full Cure Time | 7 days | | Item Form | Paste | | Item Weight | 3.52 ounces | | Liquid Volume | 2.8 fluid ounces | | Manufacturer | GordonGlass | | Material Type | Silicone | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | SG_B0063U2RT8_US | | Surface Recommendation | Pipe, Counter Top, Window, Door, Sink, Tub, Walls | | Unit Count | 2.8 Fluid Ounces | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** ASI - **Color:** Clear,Silver - **Full Cure Time:** 7 days - **Item Weight:** 3.52 ounces - **Liquid Volume:** 2.8 fluid ounces ## Images ![388 Clear Electronic Grade Silicone - 2.8 oz Squeeze Tube - Image 1](https://m.media-amazon.com/images/I/61xK5SRrz8L.jpg) ## Frequently Bought Together - Clear Electronic Grade Silicone - 2.8 oz Squeeze Tube - Lesnow solder wick braid 10ft Length Desoldering Wick Braid Remover Tool Solder Sucker 1 piece No-Clean soldering Wick Wire Roll and Disassemble Electrical Components - Chip Quik EGS10W-20G Electronics Grade Silicone Adhesive Sealant 20g (0.7oz) Squeeze Tube (White) for Precision Dispensing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/5611514-388-clear-electronic-grade-silicone-2-8-oz-squeeze-tube](https://www.desertcart.jp/products/5611514-388-clear-electronic-grade-silicone-2-8-oz-squeeze-tube) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-28*
