Absorptive Coatings

MAST Technologies’ absorptive caulking materials are magnetically loaded RF absorber / microwave absorber materials fabricated to be electrically equivalent to the MAST Cavity Resonance sheet products. The materials can be manufactured using one or two part systems in a variety of viscosities. Absorber caulk can be used for in small quantities for prototyping and test, or in production via automated dispensing systems.
