It offers superior dielectric properties, waterproofing, and corrosion resistance while curing odorlessly to a flexible, durable rubber. Perfect for protecting sensitive metals like copper and brass, it withstands extreme temperatures from -57°C to +204°C, making it a trusted choice for professional electronic assembly and repair. ## 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: LED silicone - electronics save silicone if you’re working with delicate electronics or LED light strips that you wanna make waterproof where you solder them to the strips this works well Review: Great for electronics - 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. ## 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 | #6,338 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #18 in Silicone Adhesives | | Brand | ASI | | Brand Name | ASI | | Color | Clear,Silver | | Customer Reviews | 4.6 out of 5 stars 671 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 ![ASI 388 Clear Electronic Grade Silicone - 2.8 oz Squeeze Tube - Image 1](https://m.media-amazon.com/images/I/61xK5SRrz8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ LED silicone *by D***S on June 25, 2026* electronics save silicone if you’re working with delicate electronics or LED light strips that you wanna make waterproof where you solder them to the strips this works well ### ⭐⭐⭐⭐⭐ 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.
