Low Viscosity Fast Flow Grade Two Component Tank Sealant Jelly Gel

Product Overview:

Hong Ye HY-9400 is a premium two-component addition-cure platinum catalyzed blue jelly gel specifically engineered for zero-leakage liquid tank sealing in bag-in/bag-out (BIBO) filter housings for high-containment pharmaceutical and biosafety facilities. With a buttery soft consistency measured at a penetration of 200 plus or minus 30 (0.1mm) and a permanently tacky surface, HY-9400 delivers reliable long-life sealing and protection that outlasts conventional gaskets, foams and caulks by a wide margin. The product is mixed 1:1 by weight, self-levels after pouring, cures at room temperature within 4 to 6 hours, and requires no vacuum degassing, making it one of the easiest high-performance gels to deploy on production lines worldwide. As a low viscosity fast flow grade, this variant pours easily into narrow channels and complex cavities, levels quickly with minimal bubbles, and is optimized for automated meter-mix dispensing on high-speed lines. It is specifically formulated for the knife-edge gel channels of BIBO housings used with high-potency pharmaceutical compounds, cytotoxic drugs and BSL-3/BSL-4 laboratories, where filters are changed inside sealed protective bags without exposing personnel or the room to hazardous contaminants. The gel must withstand repeated hydrogen peroxide vapor (VHP) and formaldehyde decontamination cycles while remaining soft and resealable. (EN) Backed by Hong Ye’s nearly 20 years of silicone manufacturing expertise and supplied to customers in over 60 countries, HY-9400 combines the performance of premium imported gels with the cost efficiency, short lead time and responsive technical support of a Chinese manufacturer. Whether you are running a first sample trial or ramping to full production, Hong Ye delivers consistent batch-to-batch quality, comprehensive documentation and application engineering support from first sample through full production.

Key Features:

• Low viscosity fast flow formulation fills narrow gaps and intricate cavities quickly, self-levels with minimal bubbles and suits automated dispensing.

• Repairable and reworkable: old gel can be topped up with fresh gel without full removal

• No VOC emissions during or after cure, suitable for enclosed cleanroom and medical environments

• Can be heat-cured at 60-80C for 30-60 minutes to shorten demolding time in mass production

• Resistant to ozone, UV, moisture, salt spray and common cleanroom cleaning agents

• 1:1 mix ratio by weight, easy to meter with manual or automated dispensing equipment

• Compatible with automated meter-mix dispensing equipment for high-volume production lines

• 12 month shelf life when sealed and stored below 25C in dry ventilated conditions

• Third-party test reports including RoHS, REACH, FDA and LFGB available on request

• Self-leveling after pouring, no vacuum degassing required, saving process time and equipment

Model Selection Guide:

The HY-94 series offers three standard grades to cover the full range of jelly gel applications, and custom formulations are available for volume orders:

HY-9400 (Blue, High Tack, Penetration 200): The softest and most aggressive grade, designed for HEPA/ULPA filter gel seals in cleanrooms, biosafety cabinets, pharmaceutical GMP facilities, hospital operating rooms, semiconductor fabs, lithium battery dry rooms and data centers. Choose this model when maximum self-healing and conformability to knife-edge channels are the high priority.

HY-9405 (Blue, Medium Tack, Penetration 170): The balanced all-rounder for instrument meter sealing, electronic encapsulation and outdoor waterproofing. Typical applications include smart water/gas/electric meters, automotive ECUs and sensors, solar PV junction boxes, LED modules, underwater lights, battery management systems and pressure sensors. Choose this model when you need a combination of flowability, structural support, vibration damping and repairability.

HY-9409 (Transparent, Low Tack, Penetration 150): The premium skin-contact grade for intimate apparel and medical products. Typical applications include silicone bra pads, push-up inserts, breast prostheses, nipple covers, bridal and swimwear gel pads, orthopedic insoles, baby products and surgical positioning pads. Choose this model when clarity, dry skin feel, anti-yellowing and body-safe materials are required.

If your project requires a different penetration, color, cure speed or special certification (FDA, LFGB, UL94), contact Hong Ye technical support for a custom formulation. Custom MOQ starts from 20kg and typical lead time is 7 to 10 working days.

Recommended Application: BIBO Bag-in-Bag-out Filter Housing Gel Seal

Quality & Compliance:

Every batch of Hong Ye HY-94 series jelly gel is manufactured under ISO 9001 certified quality management and tested for viscosity, mix ratio, cure time, penetration, color and tack before release. A Certificate of Analysis (COA) is provided with every shipment. Standard grades are tested to RoHS 2.0 and REACH SVHC requirements. The transparent skin-contact grade uses food-contact grade raw materials and can be supplied with FDA 21 CFR 177.2600 and LFGB Section 30/31 test reports on request. All products carry a 12 month shelf life from manufacture date when stored sealed below 25C. Hong Ye has supplied jelly gel to cleanroom contractors, electronics manufacturers, meter makers, intimate apparel brands and medical device OEMs in over 60 countries since 2005.

Packaging:

Standard packaging options include 1kg trial kits (500g A + 500g B), 5kg kits, 20kg pails, 25kg pails and 200kg drums. Components A and B are supplied in separate containers within each kit. Custom packaging and private labeling are available for orders above 200kg. All kits are clearly labeled with batch number, manufacture date, expiry date and safety information.

Ordering and Logistics:

To order, contact Hong Ye sales with your required model, quantity, destination country and preferred courier. We accept T/T bank transfer, PayPal for sample orders, and Alibaba Trade Assurance for online orders. Sample and freight details are available on request. Standard packaging ships from stock within 3 to 5 working days after payment. We ship worldwide via DHL, FedEx, UPS and sea freight for bulk orders. Addition-cure silicone gel is not classified as dangerous goods under most transport regulations, simplifying international shipping. All shipments include commercial invoice, packing list, COA and safety data sheet.

Precautions:

Use polyethylene, nylon or nitrile gloves; never use natural rubber latex gloves. Avoid contact with sulfur-containing materials, amines, phosphorus compounds, tin-cured silicone and PVC, as these inhibit the platinum catalyst and prevent cure. Mix A and B at exactly 1:1 ratio by weight using a calibrated scale. Stir thoroughly for 3-5 minutes, scraping container walls and bottom. Do not exceed 100C during heat curing. Ensure good ventilation during operation.

Storage:

Store sealed containers in a dry, ventilated area below 25C, away from direct sunlight, sulfur-containing materials, amines, food and strong chemicals. Shelf life is 12 months from manufacture date. Reseal unused material immediately after dispensing. Refrigerated storage at 5-15C can extend shelf life; allow material to return to room temperature before opening to prevent condensation.

FAQ:

Q: How long does the gel take to cure and can I speed it up?

A: At 25C the gel reaches touch-dry in 4 to 6 hours and full properties after 24 hours. For mass production, heat-curing at 60 to 80C reduces demolding time to 30 to 60 minutes. Do not exceed 100C as it may cause discoloration or surface defects. Low temperatures below 15C will significantly slow the cure.

Q: Will the gel self-heal after a filter is removed and reinserted?

A: Yes. The cured gel remains permanently tacky and soft. When the knife edge is lifted, the gel temporarily separates; when reinserted, it flows back around the blade within minutes, restoring the airtight seal. This self-healing property is a key advantage over compressed gaskets and is especially valuable during periodic filter replacement.

Q: What is the shelf life and how should the gel be stored?

A: Sealed containers have a 12 month shelf life when stored below 25C in a dry, ventilated area away from direct sunlight. Reseal unused material immediately. Keep components A and B separate and away from sulfur-containing materials, amines, food and strong chemicals.

Q: Can old gel in a filter tank or housing be topped up?

A: Yes. If the existing gel is still clean, soft and tacky, wipe the surface with a dry cloth and pour fresh gel on top. The fresh addition-cure gel bonds chemically to the clean cured gel. If the old gel has hardened, dried out, yellowed or become contaminated, remove it completely, clean the channel and refill.
