Polyurethane Potting Compound for LED Point & Strip Light Source
Point light sources are commonly employed for outdoor building screens and outlines, with wire connections linking the points. Their sealing, waterproofing, moisture-proofing, and vibration resistance mainly depend on the potting glue compound. LED light strings are typically utilized for LED luminous characters and advertising light boxes. The adhesive used must exhibit strong adhesion to the plastic shell, while the filling glue is expected to retain both hardness and elasticity outdoors for convenient installation.
GLUDITEC high-performance polyurethane and high-performance silicone are used in LED products such as point light sources and light strings. The characteristics and advantages are as follows:
- Ensure compatibility with standard plastic and metal surfaces. GLUDITEC PU potting compound exhibits strong adhesion to commonly used plastic and metal substrates. Before bulk usage, we can support customers by conducting tests to ensure they meet your company’s requirements.
- The cured potting compound provides effective sealing and waterproofing for the lamp, achieving a waterproof level of IP67 or higher based on the lamp’s structure as per customer specifications.
- Various GLUDITEC potting compounds are designed to meet specific technical requirements based on the customer’s need, complying with RoHS, Reach, PaHs, and other environmental standards.
- Its exceptional weather resistance allows our potting compound to meet the unique demands of different LED lamps in various operating environments.
