Technical Parameters

Target Applications

1. Residential Water Purifier Cartridge Sealing: Seals end caps of PP cotton and activated carbon filters in household water purifiers, ensuring filtration efficiency and longevity
2. Industrial RO Membrane Module Bonding: Bonds end plates of reverse osmosis (RO) and nanofiltration (NF) membranes, withstanding high-pressure water flow
3. Ultrafiltration (UF) Membrane Assembly: Secures hollow fiber UF membranes, maintaining uniform filament spacing and improving filtration performance
4. Laboratory Membrane Column Preparation: Enables rapid encapsulation of small-scale membrane separation columns for research applications

Critical Curing & Handling Precautions

1. Temperature Sensitivity: Preheat materials when working below 15°C to maintain optimal flowability and curing speed
2. Proper Mixing: Ensure thorough mixing of resin and hardener to avoid incomplete curing and performance degradation
3. Clean Surface Preparation: Remove dust, grease, and moisture from membrane surfaces before application to ensure strong adhesion

Directions for Use

1. Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc.
2. Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
3. Accurate Proportioning: Manual operation requires precise mixing according to the specified ratio and recording. Machine potting requires calibrated ratios and first-article confirmation is recommended.
4. Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
5. Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
6. Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
7. Curing: Allow the potted and inspected products to cure at room temperature or with heat assistance (recommended 60°C if needed), according to product and process requirements.
8. Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.

   9. This series of products are room-temperature-curing, addition-cure two-component silicone. During the dispensing process, avoid contact with the following three types of materials to prevent reactions that may affect the curing effect:

   a. Organotin compounds and organotin-containing silicone rubber.

   b. Sulfur, sulfides, and sulfur-containing materials.

   c. Amine compounds and amine-containing materials.

   10. It should be noted that during manual operation, when vacuumizing the mixed A+B adhesive, the vacuum pressure must be controlled to ensure the adhesive is not completely sucked out of the container by the vacuum.

• Specialized Industrial Equipment: Protecting components in aerospace water systems, military-grade purification units, and high-pressure membrane separation systems.

Q2: What distinguishes "modified" epoxy potting compounds from standard epoxies?

A2: Baizhuang's modified formulations incorporate targeted additives to address specific application challenges:

• Flexibility Modifiers: Enhance impact resistance for mobile or seismic-prone equipment (e.g., BZ-609-1 for portable water treatment systems).
• Low-Temperature Curing Agents: Enable fast curing in cold environments without large heating facilities (e.g., EX605-45-2 for winter production).
• Filament-Safe Additives: Prevent damage to delicate PVDF membrane fibers during encapsulation (e.g., EX605 series for water treatment modules).
• UV Stabilizers: Resist yellowing in outdoor LED displays and craft applications (e.g., BZ-710-T for crystal photo encapsulation).

Q3: How do curing times vary across Baizhuang's epoxy product lines?

A3: Curing times are tailored to application needs, with options ranging from rapid to extended cycles:

• Fast-Curing Formulations: Cure in 2–6 hours at room temperature for high-volume production (e.g., BZ-710 series for LED modules).
• Standard Industrial Curing: Require 6–24 hours at room temperature for water treatment membrane modules (e.g., BZ-609, BZ-709 series).
• Extended Pot Life: Offer 4–6 hours of working time for complex assembly operations (e.g., EX605-35 for large-scale PVDF membrane systems).
• Heat-Accelerated Curing: Reduce cure time to 20 minutes–4 hours with temperatures between 60–80°C (e.g., BZ-306 for emergency repairs).

Q4: What chemical and environmental resistances do these compounds offer?

A4: Baizhuang's epoxies are engineered for harsh operating conditions:
