PUR Hot Melt Adhesive for LED Lighting Positioning

Application Overview

SINOHESIVE PUR hot melt adhesive for LED lighting component positioning is designed for dispensing, bonding, and fixing LED lighting components and electronic products.It is suitable for bonding and positioning glass, ABS plastic, metals, and other common materials. The adhesive can be used during assembly for dispensing, alignment, and initial fixation of lighting components, providing reliable bonding support for subsequent pressing and long-term use.

Low VOC & Environmentally Responsible

SINOHESIVE focuses on PUR adhesive solutions that support lower-VOC manufacturing.The adhesive uses a 100% solids system and contains no added aldehydes, ketones, benzene-based compounds, hydrocarbons, or esters.It is well suited for LED lighting component positioning projects where manufacturers place greater emphasis on the production environment, product odor, and material compliance.

Key Benefits

High Initial Tack for Reliable Positioning

The adhesive provides high initial tack, helping LED lighting components achieve fast and reliable initial positioning.This helps reduce the risk of spring-back or component misalignment after bonding or pressing.

Compatible with Glass, ABS & Metal Materials

The adhesive is suitable for bonding glass, ABS plastic, metals, and other materials commonly used in LED lighting assemblies.It supports dispensing, fixing, and assembly requirements involving different material combinations.

Suitable for Fast Dispensing and Fixing

The adhesive provides an open time of approximately 20–50 seconds, supporting rapid dispensing, alignment, and bonding of LED lighting components.Actual working time may vary depending on adhesive application amount, material temperature, ambient temperature, and equipment condition. Process validation is recommended before full-scale production.

Excellent Durability

After curing, the adhesive layer provides good resistance to heat, cold, water, and chemicals.This helps support reliable bonding of LED lighting components under different operating and environmental conditions.

Application Support for Your LED Lighting Component Positioning Project

Final positioning and bonding performance can be affected by lighting component structure, glass, ABS, or metal surface condition, dispensing location and adhesive amount, assembly accuracy, equipment condition, and processing parameters.

SINOHESIVE can provide sample testing and adhesive selection support based on your specific project requirements, helping you complete the necessary validation before full-scale production.
