Polyurethane Potting Compound
for Rigid LED Strips and Linear Light Source
Outdoor LED light including Rigid LED Strips and Linear Light Source. GLUDITEC high-performance polyurethane potting compounds are widely used in this LED light equipment in different places such as bars, advertising boards, outdoor displays, street lighting, etc.
These rigid LED strips and linear light sources are typically employed outdoors to delineate the outlines of various buildings. These lamps need to be able to withstand different outdoor environments, making outdoor potting glue a crucial component. Therefore, selecting appropriate potting glue becomes a top priority.
The characteristics and advantages of GLUDITEC high-performance polyurethane and high-performance silicone products used in LED lighting products are as follows:
- As outdoor linear lights come in various models with different designs, GLUDITEC potting compounds with different viscosity and open time can fit in these different products and processes (both manual and automated potting processes).
- GLUDITEC PU potting compound exhibits strong adhesion to commonly used plastic and metal substrates. Before bulk usage, we can support customers to conduct 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.
- To address the yellowing resistance needs of outdoor lamps, specific models are available that guarantee resistance to yellowing and heat outdoors for 2 to 5 years for different glue-filled products as required by customers.
