1. Product Overview

CEMEDINE SX720 is a non-flammable (UL94 V-0 listed), one-part, solventless adhesive designed for electrical components. It provides:

  • Quick curing at normal temperature
  • High initial adhesion and durability
  • Excellent electrical insulation
  • Environmentally friendly formulation (free from low-molecular siloxane, halogens, antimony oxide, phosphorus-based materials, and volatile solvents)

2. Applications

  • Fixing circuit boards, including condensers and coils
  • Sealing electronic components for waterproofing
  • Sealing power supplies and transformers for insulation
  • Prevention of electrical contact failures
