BoNimide

SKU: 1188 Category: Tags: , , , , , , , , , , , , , , , , ,

BoNimide is an easy-to-apply, nonaqueous, paintable boron nitride (BN) coating with an imide precursor that is designed to seal surfaces, prevent reactions, improve tribological properties and provide electrical insulation.  Once applied and cured at 150-250 C, BoNimide is usable in any atmosphere to 400-600 C.  Higher cure temperatures lead to a higher degree of polymerization.  The polymerized  coating forms a tough, abrasion-resistant, chemically resistant barrier on almost any substrate: metals (aluminum, stainless and carbon steels), ceramics, graphite or carbon/carbon, specialty textiles (Kevlar, Nextel, Nicalon, fiberglass, metal textiles) and composite materials.  Ideal for use where polytetrafluoroethylene (PTFE) and silicone fail to perform due to use-temperature environments or bans on “forever chemicals”.

Price range: $50.00 through $360.00

Key Attributes

  • Provides an abrasion-resistant, lubricating sealant coating upon drying and curing
  • Protects from liquid hydrocarbons, solvents, acids, oil, and grease
  • Protects from vapor attack and condensation (as liquid) reactions
  • High electrical resistivity: 107 megaohms from the PI matrix
  • Improves tribological properties
  • Easy to use: applies like house paint by brushing or dipping
  • Contains no CMR (carcinogenic, mutagenic, or reprotoxic) solvents
  • Protects from corrosion and wear of metal parts
  • Special properties with BN, including neutron absorption

Ideal Uses

  • Sealing/protecting surfaces (porous or dense) from harsh, aggressive chemicals, including sulfuric acid (liquid and vapors), as well as protecting from water and steam attack
  • Electronic applications to prevent electrical breakthrough
  • Tribological applications for lubricity and wear/erosion resistance
  • Highly corrosive environments, such as papermaking processes
  • For aiding extrusion and processing of problematic polymers (Nylons/Polyamides, Polycarbonates, Santoprene ThermoPlastic Vulcanizate (TPV), Ultra-High-Molecular-Weight Polyethylene (UHMWPE))
  • Where higher use-temperatures (i.e., above 400 °C or 752 °F) are required—beyond that of PTFE or silicones
