Fast-Cure Nano Conformal Coat

YNT-SF-001

As electronic products become smaller and more integrated, components are denser and more fragile.
Iridium Technology’s Ultra-Thin Nano Conformal Coat differs from traditional conformal coatings by offering seconds-to-cure fast drying, efficient heat dissipation, and full waterproof protection, significantly reducing application time and cost while ensuring long-term reliability and environmental safety.

Core Functions & Advantages
Slide

Advanced Protection
● Innovative superhydrophobic liquid nano coating providing insulation, anti-static, moisture-proof, anti-mold, and salt-spray protection
● Exceptional durability: resistant to chemical corrosion, extreme temperatures, and electrical stress
● Comprehensive coverage without interference: 360° protection of PCBA including connectors, switches, antennas, without affecting signal transmission

Ultra-Thin & Heat-Dissipating
● Ultra-thin design: moisture-proof layer

Fast-Cure
● 5-second fast curing, enabling efficient transition to subsequent processes
● Uniform, complete coverage of the material surface for full immersion coating
