5-Year Anti-Yellowing Clear PU Potting for Labels & Nameplates

Product Description

BZ-4117 is a high-transparency, yellow-resistant polyurethane potting adhesive compliant with ROHS, REACH, and California 65 standards. Developed for surface coating on nameplates, labels, printed materials, and crafts, it serves as a self-leveling decorative encapsulant. Upon curing, it forms a three-dimensional crystal-clear surface with optimal hardness, remaining flexible even at low temperatures. It resists both UV-induced and thermal yellowing for up to five years, ensuring lasting product protection and visual appeal.

Key Product Features

1. Excellent weather resistance and UV stability.
2. Heat-accelerated curing for improved production efficiency.
3. Complies with ROHS, REACH, and California Proposition 65 environmental requirements.
4. Two-component system with straightforward processing and moderate flow characteristics.
5. Ideal for potting or doming nameplates and labels, delivering a three-dimensional effect with crystal-like gloss after curing..

Technical Parameters

Product Applications

1. Nameplates: High transparency with a three-dimensional crystal effect, maintaining clarity and colorfastness for extended periods.
2. Label: Resistant to yellowing, maintains shape and prevents lifting at low temperatures.
3. Crafts: Resistant to extreme temperatures, non-crisp, highly transparent, and resistant to yellowing or discoloration;
4. Printed materials: Protect the printed layer to enhance the three-dimensional effect of patterns and text.

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.

Packing & Shipping & Storage

Hardener: Typically 5KG/ 10KG / 20KG metal or plastic drums.

Resin: Typically 5KG/ 10KG / 20KG metal or plastic drums.

Store and transport as a general chemical product.

Store sealed, protected from light at room temperature. Shelf life varies from 6 to 12 months depending on packaging; please refer to the expiry date on the shipping package.

When temperature drops to 15°C or lower, the hardener or resin should be stored in a warm place or heated before use for potting. Specific heating recommendations depend on the temperature drop; please communicate and consult with us.
