Repairability Moves Gel to Mainstream

Electronics manufacturers servicing warranty on outdoor products (charging piles, IoT nodes, controllers) report that scrap-from-potting and unrepairable field returns add more cost than the saving from cheap epoxy. Soft jelly gel has therefore moved from niche to mainstream specification for repairable designs. Hong Ye HY-9405 supplies the balance at Chinese manufacturing cost with full documentation and dispensing support. The market trend favors reworkable encapsulants as right-to-repair regulations and circular-economy requirements advance in major export markets.

PRODUCT REQUIREMENTS

Serviceable electronics potting requires: waterproof and dielectric protection equal to rigid systems; near-zero stress on solder joints; hand or tool peelability without pad damage; fresh-gel re-bonding after repair; competitive material cost; and production-line compatibility. In repairable detail, the gel must peel off as a sheet by hand or tool after full-board potting without lifting solder mask or small components. Dispensed within 20-40 minutes of mixing and cured to penetration 170+/-30 in 4-6 hours, its waterproof and dielectric performance matches rigid systems. After cleaning the repair surface, fresh gel wets and bonds well, with near-zero stress near joints. It withstands damp heat, salt fog and cleaners without oil bleeding; automated shot weights are stable, material cost and process window support high-volume production, and batch COA is supplied.

GRADE SELECTION GUIDE

The HY-94 series offers three standard jelly gel grades for liquid-channel sealing, soft electronic potting and body-contact gel products. Their color, cone penetration, tack and typical applications are described below so users can choose the grade that matches sealing force, shape retention and processing needs.

HY-9400 is a blue grade with cone penetration 200 (0.1mm) and high tack. It is mainly used in HEPA/ULPA filter gel channels and biosafety cabinet seals, and in other applications that require strong adhesion and repeatable re-sealability.

HY-9405 is a blue grade with cone penetration 170 (0.1mm) and medium tack. It is recommended for electronic potting and sensor encapsulation, and for applications that balance softness with dimensional stability.

HY-9409 is a transparent grade with cone penetration 150 (0.1mm) and low tack. It fits transparent gel pads, intimate apparel and prosthetic devices, and other applications that require visual clarity or easy repositioning.

FREQUENTLY ASKED QUESTIONS

Q: Is jelly gel as waterproof as epoxy?

A: In outdoor electronic modules, yes: full-contact gel potting reaches IP67/68-equivalent water blocking; epoxy’s advantage is mainly structural hardness, which serviceable modules do not need.

Q: Will peeling damage the PCB?

A: No. The soft gel separates from boards and components without lifting pads, unlike cutting rigid silicone or epoxy.

Q: Does fresh gel bond to old gel after repair?

A: Yes. Addition-cure gel bonds to cured gel of the same family; the repaired seal passes the same water tests as new potting.

QUALITY ASSURANCE & CERTIFICATION

Every batch of Hong Ye HY-94 series jelly gel is produced under ISO 9001 certified quality management in a dedicated silicone workshop, with incoming raw-material inspection, in-process mixing control and finished-product testing on every batch. Before release each lot is checked for viscosity, mix ratio, cure time, penetration, color and tack, and a Certificate of Analysis (COA) listing the actual measured values ships with every order. Standard grades carry RoHS 2.0 and REACH SVHC test reports; skin-contact and baby-care grades can be supplied with FDA 21 CFR 177.2600 and LFGB Section 30/31 reports and, on request, ISO 10993 biocompatibility testing; flame-retardant grades meet UL94 V-0. Food-contact, medical and export orders are supported by the corresponding compliance files for customer qualification. Hong Ye has manufactured and supplied jelly gel to contractors, filter builders and equipment makers in over 60 countries since 2005, with monthly capacity above 500 tons, batch traceability and multi-language documentation. Application engineers provide grade selection, sample evaluation, on-site or video pouring guidance and after-sales follow-up, and technical data sheets (TDS), safety data sheets (SDS) and test reports are available before order to support tender and audit processes.
