It offers exceptional dielectric properties, waterproof protection, and resistance to extreme temperatures and environmental factors. Its odorless curing process and flexible, durable finish make it ideal for safeguarding sensitive components like copper, brass, and silver in both confined and large-scale production settings. ## 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) Review: Great stuff! - Worked great, hopefully resists high voltage RF! Review: Works as advertised - Used it on a drone rebuild and it worked just fine. Also a good value ## 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 | #9,835 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #27 in Silicone Adhesives | | Brand | ASI | | Brand Name | ASI | | Color | Clear,Silver | | Customer Reviews | 4.7 out of 5 stars 650 Reviews | | Full Cure Time | 7 Days | | Item Form | Paste | | Item Weight | 0.22 Pounds | | Liquid Volume | 2.8 Fluid Ounces | | Manufacturer | GordonGlass | | Material Type | Silicone | | Number of Items | 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:** 0.22 Pounds - **Liquid Volume:** 2.8 Fluid Ounces ## Images ![ASI 388 Clear Electronic Grade Silicone - 2.8 oz Squeeze Tube - Image 1](https://m.media-amazon.com/images/I/61xK5SRrz8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great stuff! *by D***K on March 10, 2026* Worked great, hopefully resists high voltage RF! ### ⭐⭐⭐⭐⭐ Works as advertised *by L***N on May 3, 2026* Used it on a drone rebuild and it worked just fine. Also a good value ### ⭐⭐⭐⭐⭐ Great for electronics *by A***D on December 6, 2025* I used this primarily to vibration-proof a somewhat-risky component substitution for an obsolete part. I would have liked something that cured a bit stiffer, but it's probably perfectly fine. And making it stiffer would probably make it less general-purpose than it is. Seems like a quality product. Noobs beware - if it smells like vinegar, IT'S NOT FOR ELECTRONICS! Do it right or don't do it. This is the right stuff. ## 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.gr/products/5611514-asi-388-clear-electronic-grade-silicone-2-8-oz-squeeze](https://www.desertcart.gr/products/5611514-asi-388-clear-electronic-grade-silicone-2-8-oz-squeeze) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-31*
