BZ-6100-5C: High-Hardness Polyurethane Adhesive for Structural Applications
BZ-6100-5C is a two-component polyurethane adhesive engineered for structural bonding applications, offering high hardness, excellent adhesion, and superior mechanical strength in demanding environments. With a higher mixed viscosity and Shore D hardness, it provides enhanced load-bearing capacity and dimensional stability for heavy-duty construction materials. This adhesive complies with RoHS standards and provides good temperature resistance and weatherability, making it suitable for both indoor and outdoor structural applications.
Key Product Features
- High Hardness & Strength: Shore D hardness of 75±10 and ≥12 MPa tensile strength ensure exceptional load-bearing capacity and dimensional stability in structural applications, even under heavy mechanical stress.
- Balanced Curing Speed: Achieves surface drying in 2.5±1 hours and full curing in 4±1 hours at 25°C, providing sufficient working time for precise assembly while enabling efficient production cycles.
- Adjustable Pot Life: 20±8 minutes at 25°C (adjustable) allows flexibility in working time, accommodating both manual and automated processes in structural manufacturing.
- Excellent Substrate Compatibility: Bonds effectively to aluminum honeycomb panels, sandwich panels, and heavy-duty composite materials, as well as steel and concrete substrates, eliminating the need for surface treatments in most cases.
- Low Water Absorption: ≤0.5% absorption in 24 hours ensures reliable performance in humid or outdoor environments, preventing delamination and maintaining bond integrity over time.

Directions for Use
- Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc.
- Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
- 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.
- Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
- Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
- Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
- 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.
- Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.
Packaging & Shelf Life
- Packaging: 25kg plastic drums, 200kg steel drums, and 1000kg IBC totes for both Component A (brown) and Component B (beige).
- Shelf Life: 3–6 months from production date when stored sealed, protected from light at room temperature.
- Opened Container: Use within 3 days for optimal performance; stir thoroughly before use if stored longer.
