High-Clarity Yellow-Resistant PU Potting with Fast Cure
BZ-5518-3-X-1 is a highly transparent, anti-yellowing polyurethane potting compound designed for decorative wall coverings and printed graphics. It meets ROHS, REACH, and California 65 standards. Upon curing, it forms a crystal-clear, three-dimensional surface with balanced hardness—staying flexible and crack-free even in low-temperature conditions. The material maintains its original color for three years without yellowing, delivering lasting visual appeal and protective performance.

1. Decorative wallpaper: High transparency and accelerated curing properties, achieving over 300% higher production efficiency than epoxy resin; soft and long-lasting smooth surface without peeling after curing.
2. Printing materials: same as above;
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.
Hardener: Typically 20KG/ 200KG metal or plastic drums.
Resin: Typically 20KG / 200KG 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.
