500-210 General Purpose Conformal Coating

500-210 General Purpose Conformal Coating

500-210 is a balanced-performance silicone coating featuring a room temperature alkoxy moisture cure that can be accelerated with heat. Soft enough to reduce strain on components while being tough enough to resist abrasion. As one of our 500 Series Electronics-grade silicones, 500-210 is a neutral cure (alkoxy) sealant suitable for spraying or flow coating. It’s a ready-to-use, room temperature moisture cured silicone that cures to a resilient rubber that is tough enough to resist abrasion, yet soft and compliant enough to reduce strain on electronics components. When a non-corrosive product is required, this is an alternate unprimed adhesive solution that:

  • Delivers a more uniform bond
  • Provides a barrier coating to protect against moisture and dust
  • Helps dampen vibrations

A translucent liquid, 500-210 has a viscosity of ~ 1,000 cPs and begins to gel in fewer than 25 minutes.

    Product information:

    Novagard’s 500 series moisture-cure conformal coatings and sealants achieve primer-less adhesion to electronics substrates such as FR4, plastic, copper, and other metals. The inside-out cure provides longer working times and low odor, and are free of solvents with no isocyanates.

    Certain materials, chemicals, curing agents, and plasticizers may inhibit the cure. The most notable are organotin catalysts, amino compounds, polysulfide, and other sulfur-containing materials. Do not use in or around highly oxidative chemicals such as liquid oxygen, chlorine, or peroxides. Not recommended for surfaces that are to be painted.
