Room temperature cure nano-coatings


Nano-coatings protect circuit boards but do not require maskingNano-coatings have very specialised properties for protecting circuit board assemblies.

SCH provide two proprietary low temperature fluoropolymer coating formulations, LT-4 and LT-8.

The two nano-coatings have similar protection properties but differ in liquid carrier.

Why use nano-coatings to protect circuit boards?

Performance properties of LT-4 and LT-8

The fluorocarbon coatings have excellent physical properties:

  • Hydrophobic and oleophobic surface performance
  • Superior moisture and salt barrier properties
  • Corrosion resistant
  • High resistance to chemicals/solvents
  • Resists heat to 200C
  • Survives Gamma, E-beam and EtOH sterilization
  • Good adhesion
  • Will not occlude fine gauge mesh openings
  • Well suited for: pcb, electronics, metals, MEMS, sensors, plastics, steel mesh, membranes, fabrics
  • Adaptable and customisable chemistry
  • Re-workable, solderable
  • Optically clear liquid formulation
  • Film thickness from 200 nanometers to 2+ microns
  • Varying fluorocarbon solids from 0.1% upwards
  • Transparent, colorless film
  • Low viscosity, low surface tension solution

LT-4 and LT-8 difference

The difference between the two coatings (LT-4 and LT-8) is the solvent carrier.

The LT-coating 4 is based upon standard solvents (acetone, butyl acetate) and MEK and provides a commercially price sensitive solution.

The LT-8 coating uses a fluorosolvent carrier that is a safe alternative to the environment and the operator.

Why use nano-coatings to protect circuit boards?


Nano coatings are no mask conformal coatings with great water repellent propertiesNano-coatings have very specialised properties for protecting circuit board assemblies.

They include:

  • Being highly hydrophobic (water repellent)
  • Having a high moisture barrier
  • Being ultra-thin so no requirement to mask the circuit board
  • Being highly oleophobic (oil repellent)
  • Having a high chemical resistance
  • Having a high lubricity
  • Having high dielectric properties
  • Providing high corrosion resistance

The fluoropolymers are extremely flexible coatings and becoming more prolifically used throughout engineering.
