111-27DIELECTRIC COATING介質涂層

111-27
 DIELECTRIC COATING
DESCRIPTION: 111-27 is a flexible, electrically insulating coating suitable for application by spraying, dipping and
syringe dispensing. This product features excellent adhesion to Kapton, Mylar, glass, and a variety of other
surfaces. Unlike conventional insulating materials, this product is very resistant to flexing and creasing. Some
applications for 111-27 include, but are not limited to, insulating polyimide flexible circuits, polymer thick film
circuitry, and membrane switches. 111-27 also protects components from moisture, salts, and abrasion.
TYPICAL CURED PROPERTIES:

SUGGESTED HANDLING & CURING: Further thinning for spray and/or dip coating may be accomplished by
adding MEK. Best properties for most applications result when allowed to be cured for 3 minutes at 130°C. Good
properties are obtained on a variety of substrates by curing at temperatures ranging from 25°C to 150°C. End user
is advised to experimentally determine temperature and time best suited for individual applications.
STORAGE: Shelf Life: 6 months at 21°C.
SAFETY & HANDLING: Use with adequate ventilation. Keep away from sparks and open flames. Avoid prolonged
contact with skin and breathing of vapors. Wash with soap and water to remove from skin. Keep containers closed
to avoid contamination; moisture may cause polymerization. Purge opened containers with an inert gas blanket
before resealing.
