Fast-Build Filter Sealing for Fangcang Shelter Hospitals and

1 Introduction
Emergency shelter hospitals, modular isolation wards and field medical units are built in days or weeks, with negative-pressure ventilation and HEPA exhaust filtration installed and commissioned under extreme schedule pressure. Sealing these filters with conventional gaskets requires precise compression hardware and long curing adhesives; Hong Ye HY-9400 jelly gel offers a faster path: the 1:1 mix is poured on site into prefabricated aluminum or steel channels, self-levels without vacuum equipment, and cures in 4-6 hours at room temperature, or 30-60 minutes with simple 60-80C heating, allowing same-day filter installation and commissioning. The blue gel gives visual fill confirmation for inspection teams, the durably tacky mass self-heals when filters are replaced during the facility’s operating period, and zero-VOC cure suits immediate occupancy by patients and staff. A 20-bed isolation module typically uses 8 to 15kg of gel.

2 Product Requirements
Emergency facility sealing requires: same-day pour-to-commission capability; room-temperature cure without specialized equipment; tolerance of prefabricated frame imperfections; zero VOC for immediate occupancy; self-healing filter replacement; visual fill inspection; and foolproof instructions for untrained crews.

3 Corresponding Product Model Parameters
Recommended model: HY-9400 - Blue high-tack grade for HEPA/ULPA filter gel channels and cleanroom seals

4 Frequently Asked Questions
Q: How fast can a module be sealed and commissioned?
A: With heat acceleration the gel cures in 30-60 minutes, allowing pour, filter installation and commissioning within a single shift.
Q: Do local crews need special training?
A: No. The 1:1 hand-mix process with pictorial instructions lets general construction crews achieve inspectable seals; remote video support is available.
Q: Is the gel safe for patients right after curing?
A: Yes. Addition-cure chemistry releases no VOCs or by-products; the cured gel is odorless and non-dusting, suitable for immediate occupancy.

5 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.

6 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.
