Product Description

3318-3-7-1 potting compound is a weather-resistant transparent polyurethane specifically engineered for LED point source, LED linear lights, Outdoor LED Lighting, smart water meters, and related products. This transparent polyurethane features excellent waterproofing and moisture resistance, with the adhesive exhibiting robust structural strength, good toughness, moderate hardness, and superior yellowing resistance. Its structural strength effectively enhances the durability of LED outdoor lightting, smart water meters, and similar products in outdoor environments, humid conditions, and aquatic settings.

Key Product Features

1. Two-component polyurethane system featuring a user-friendly processing procedure and moderate flowability.
2. Compliant with RoHS and environmental regulations.
3. Can be heated to accelerate curing, offering efficient curing performance.
4. After curing, it forms a moderately hard and elastic protective layer that safeguards the electronic components of LED and smart water meters.
5. After curing, it forms a transparent protective layer with IP67 or IP68 waterproof and dustproof rating.
6. It has excellent weather resistance, with yellowing resistance lasting 2-3 years.

Product Applications

1. LED Light Sources: Provides effective protection for the LED chip and components, with IP68-rated waterproofing enabling use in riverside or water environments.
2. LED Linear Lights: Wide operating temperature range of -40 to 85°C, and 2-3 year yellowing resistance enable the lights to perform in more demanding environments..
3. Smart Water Meters: With low water absorption, they provide excellent protection for the electronic modules, enabling long-term stable operation in water immersion environments.

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.
