Outdoor Waterproof Jelly Gel Potting for EV Charging Pile Pow

INTRODUCTION
EV charging piles operate outdoors 24/7, with power modules, contactors and control boards exposed to rain ingress, condensation, road salt dust, summer enclosure temperatures above 70C and winter cold near minus 40C. Conformal coating alone cannot guarantee IP65/IP67-level protection around high-voltage terminals, while hard potting compounds trap heat and make module replacement uneconomic. Hong Ye HY-9405 jelly gel provides a soft, self-healing encapsulation: the 1:1 addition-cure gel (viscosity 1800 plus or minus 400 mPa.s, penetration 170 plus or minus 30) flows into module enclosures, seals gaps around terminals and board edges, and cures to a tacky jelly mass that blocks liquid water and humid air while remaining permeable enough to let thermal expansion breathe. Dielectric strength above 20 kV/mm supports high-voltage spacing, the gel serves from minus 60 to 200C, and damaged or upgraded modules are serviced by peeling and re-pouring. A typical 30kW charging module uses 0.5 to 1.5kg of gel.

PRODUCT REQUIREMENTS
Charging module potting requires: IP65/IP67-equivalent moisture sealing around terminals; dielectric strength above 20 kV/mm; service from minus 60 to 200C with thermal cycling; vibration tolerance in roadside cabinets; flame retardancy UL94 V-0; peelable repairability; and automated dispensing compatibility.

CORRESPONDING PRODUCT MODEL PARAMETERS
Recommended model: HY-9405 - Blue medium-tack grade for electronic potting, meter sealing, waterproofing and vibration damping

FREQUENTLY ASKED QUESTIONS
Q: Does gel potting replace gaskets for outdoor protection?
A: It complements gaskets: the gel seals internal electronics and terminals against condensation and splash, while cabinet gaskets handle bulk rain; together they reach IP65/IP67 reliability.
Q: Will the gel trap heat in high-power modules?
A: The gel’s soft consistency and thin-section application add minimal thermal resistance; designers use it around terminals and board edges, with heat sinks handling main device cooling.
Q: Can modules be repaired on site?
A: Yes. Technicians peel gel from the fault area, replace components or the board, and top up fresh gel; modules are serviced without full scrap.

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.


CONCLUSION
The market for tank sealant jelly gel in this application area continues to expand as cleanroom construction, electronic encapsulation, automotive electrification, energy storage and consumer product manufacturing drive demand for reliable two-component addition-cure silicones. Hong Ye supports this growth with ISO 9001 certified production, 500-plus ton monthly capacity, complete compliance documentation and responsive application engineering. Buyers evaluating suppliers are advised to look beyond unit price and compare batch-to-batch consistency, documentation completeness, delivery stability and technical service responsiveness, because the cost of a sealing or potting failure - rework, downtime, certification delay or product recall - far exceeds the incremental cost of a quality gel. Choosing the correct grade for the channel, operating temperature and service environment, following the 1:1 mixing and pouring procedure and validating with a small trial batch all help secure a durable seal. Hong Ye welcomes sample requests and application enquiries; our engineers will recommend the HY-9400, HY-9405 or HY-9409 grade that matches the sealing or potting requirement and support qualification from first sample through volume production.
