H.B. Fuller FH3530:


1. Product Overview

H.B. Fuller FH3530 is a two-component, liquid, castable polyurethane elastomer with no MDA, TDI, or MOCA. It has low mixed viscosity, cures to a dark amber, medium-hardness elastomer at room temperature, and features low shrinkage and excellent weather resistance.

Key Features:

  • Fungus-resistant – does not support fungal growth
  • Low shrinkage – minimal dimensional change after curing
  • Fast curing – accelerates production efficiency
  • Self-leveling – ensures even coverage
  • Non-corrosive – safe for use with metals
  • Insensitive to environmental moisture – reliable performance in various conditions
  • Low viscosity – easy mixing and pouring
  • Excellent saltwater resistance – ideal for marine applications
  • No stress cracking on PC or PE – safe for plastics

2. Applications

FH3530 is widely used in industrial applications, including:

  • Potting of sonobuoys
  • Electronics potting
  • Structural adhesive sealant applications
