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

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

Where to Use

Suitable for the renewable energy, traditional outdoor electrical, LED, consumer electronics, and electronic components industries, covering PCBA boards, precision motors, bearings, and various precision instruments.

How to Apply

Supports dip coating, spray coating, and brush coating; no need to remove old adhesives, and welding or SMT operations are unaffected, allowing direct re-coating.
