Transparent PU potting compound for 3 Years Yellowing Resistance for Nameplate

Product Description

BZ-315 is a high-transparency, yellow-resistant PU potting compound, specifically designed for surface coating applications such as labels, nameplates, and printed materials. The product complies with the requirements of ROHS, REACH, and California 65. The cured adhesive forms a three-dimensional crystal-like surface with optimal hardness, remaining flexible and non-brittle even at low temperatures. It maintains its color for up to three years without yellowing, ensuring both aesthetic appeal and durability.

Key Product Features

1. Two-component polyurethane, featuring convenient process operation, and excellent flowability.
2. Complies with ROHS, REACH, and California proposition 65 environmental requirements.
3. Can be heated to accelerate curing, offering good curing efficiency.
4. Excellent weather resistance and UV resistance
5. Widely used for potting or dripping of nameplates/plates, etc. The product after potting will present a three-dimensional effect and crystal-like luster.

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. 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/ 200KG metal or plastic drums.

Resin: Typically 5KG/ 10KG / 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.
