Electro-static Dissipative Coatings

IMESD707 UV Curable Electro-Static Dissipative Coating

ESD coating for molded plastics 

FEATURES

  • Durable abrasion and chemical resistant surface
  • Low Haze
  • Permanent non-humidity dependent static resistant surface
  • Excellent adhesion to PMMA, polycarbonate and treated PET film

BENEFITS

  • Reduces damage to surface of molded plastic surfaces
  • Protects optical quality
  • Prevents damage from static discharge
  • Environmentally durable
  • Easily applied and cured

PRODUCT APPLICATIONS

IMESD707 UV Cure coating is designed to provide surface protection and ESD protection to the surface of soft optical plastic surfaces in abusive or harsh environments and to reduce the probability events which would permanently mar the surface of the optical part and damage from uncontrolled static discharge events. This coating is suitable for PMMA and polycarbonate. IMESD707 is coated by flow, spray, dip, spin coating as well via gravure coating techniques. Users should assure the product meets the specific needs of their application(s).
