500-210 General Purpose Conformal Coating
500-210 General Purpose Conformal Coating
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 compliant enough to reduce strain on electronics components. This silicone is rated UL 746E, and UL 94 V-1. When a non-corrosive product is required, this is an alternate unprimed adhesive solution that:
-
- Delivers a more uniform bond
- Offers a stronger bond for applications where adhesion is critical
- Provides a barrier coating to protect against moisture and dust
- Helps dampen vibrations
- Simplifies production with a single component “dispense and forget” application
A translucent liquid, 500-210 has a viscosity of 450 cPs and is tack free in less than 10 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.
Applications:
- Protecting sensitive electronic components and circuit boards
- Thin-section encapsulation
- General electronics/industrial coating applications requiring a non- corrosive product
- Frame and junction box sealant in photovoltaic modules
