MICROWAVE ABSORBENT PAINT

MICROWAVE ABSORBENT PAINT: KV-SCA-P-PU-4.6 Description:

• Two parts Polyurethane/ Epoxy based magnetically loaded microwave absorbing paint.

• High magnetic loss coating to a metallic surface to attenuate surface currents/ waves.
• Part A is a resin filled with magnetic particles and Part B is an unfilled hardener.
• It can reduce Radar cross section of complex objects having discontinuities like joints, trailing edges, sharp contour etc.
• It can be used to selected parts of antennas to reduce side lobes.
• Color of coating is dark grey.
• Density of Mix. :
• Approx. 4.0 of the mixed cured system. Depending on end use it can be tailored between 3.6 to 4.6 gm/cm3.
• Thin able, spray able, brush able by using special solvent KV-SCA-P-PU-T.
• Shelf life : Minimum 6 months

• Minimum 20 dB/Cm and 63 dB/Cm at 3.0 GHz and 10.0 GHz respectively as insertion loss.
• The attenuation performance shall be tested by S21 parameter.

• Thoroughly mix Part A. Part B requires no mixing.
• For each 70 gm parts by weight of Part A add 1.0gm of Part B and mix it thoroughly. Add approx. 5 to 10 gm by weight solvent KV-SCA-P-PU-T. Single coating thickness can vary from 100 micron to 200 micron, less solvent give thicker single coating. To increase thickness apply additional coat when the earlier coat is partially cured.
• The system is room temperature curable in 24 hours.
