1. Product Overview

LOCTITE® DSP 190024™ (also known as LOCTITE® 190024™ or LOCTITE® 3703™) is a one-component, medium-viscosity, thixotropic acrylated urethane adhesive. It cures rapidly under UV or visible light and is specially designed for bonding rigid and flexible PVC to polycarbonate, with excellent gap-filling capability up to 0.25 mm. The cured adhesive provides a flexible joint that improves load-bearing and shock-absorbing performance. Its formulation ensures strong adhesion to plastics, glass, and most metals while preventing migration after dispensing.


2. Applications

  • Bonding rigid and flexible PVC to polycarbonate

  • Gap filling in assemblies (up to 0.25 mm)

  • Bonding transparent substrates where UV/visible curing is possible

  • General adhesion to plastics, glass, and metals in high-speed production environments
