73008 Low-Shrinkage Polyurethane Acrylate Resin for Electronic Potting & Metal Coating | High Temp Anti-Yellowing UV Oligomer
Product Details
Description
Product Overview: Model 73008 High-Performance Polyurethane Acrylate Resin
In the demanding sectors of electronics manufacturing and industrial metal finishing, material stability is paramount. Model 73008 is a next-generation Polyurethane Acrylate (PUA) Resin specifically formulated to address critical challenges in electronic potting adhesives, metal drop glazing, and industrial coatings.
Unlike standard acrylates, 73008 delivers minimal curing shrinkage, ensuring exceptional dimensional stability. This characteristic is vital for thick-section electronic potting, where internal stress can lead to component cracking or delamination. Its unique molecular structure provides outstanding adhesion to diverse substrates, particularly metals and glass, often eliminating the need for primers and streamlining production lines.
A standout feature of 73008 is its superior resistance to high-temperature yellowing. Engineered for harsh environments, it maintains optical clarity and mechanical integrity even after prolonged exposure to thermal stress, making it perfect for outdoor LED modules, automotive sensors, and decorative metal badges that require long-term aesthetic retention.
Compatible with solvent-free and low-VOC formulations, 73008 aligns with global environmental regulations (RoHS/REACH). It offers a balanced reactivity profile for fast UV curing without compromising final physical properties. Whether for protecting sensitive PCBs or enhancing the durability of metal coatings, 73008 provides a reliable, high-performance solution for modern industrial applications.
