In multiple fields such as electronics and PCB circuit boards, waterproof and protective performance directly relates to the product's lifespan and stability.
Betely's newly launched silicone hydrophobic agent HLD-12516 has become an ideal choice to replace fluorine-containing hydrophobic agents, providing reliable protection for various products with its core advantages of high-efficiency waterproofing, environmentally friendly and non-toxic properties, and excellent comprehensive performance.
Product Highlights
HLD-12516 is a silicone hydrophobic agent with modified polysiloxane as the main component. It uses a fluorine-free formula design. By using dipping or spraying processes, it can form a dense nano-coating on the surface of the substrate, offering multiple functions such as waterproofing, dustproofing, moisture-proofing, and insulation.
