ORMOCER®s for passivation in electronics

 

The use of ORMOCER®s as protective coatings offers the following advantages compared to other materials:

  • Availability of many different application methods (e.g. spin, dip or spray coating, curtain coating, screen and pad printing)
  • Easy modification of physical properties (e.g. viscosity: low for gaps/holes, or high, i.e. thick, for higher layer thicknesses)
  • Low water absorption and water vapor permeation
  • Good chemical resistance, even against strong acids and weak alkaline solutions, as well as organic substances
  • SMD-friendly processing conditions (e.g. low curing temperature, < 170 °C, approx. 80 °C with hardeners, solderable up to approx. 300 °C)
