EPOCAST® 1629 A/B

EPOCAST® 1629-A/B Epoxy Syntactic is a beige, flame-retardant, ultra-low-density system for edge reinforcing of honeycomb structures. It can be spread with a putty knife and resists slumping on vertical surfaces. EPOCAST® 1629-A/B can be easily sanded and machined once cured. It is a non-PBDE containing material and can be used as a replacement for EPOCAST® 87005 A/B-80 Epoxy Syntactic, EPOCAST® 87005 A/B-60 Epoxy Syntactic, EPOCAST® 87269 A/B Epoxy Syntactic, EPOCAST® 87005 A/B-61 Epoxy Syntactic, and EPOCAST® 87005 A/BE-60 Epoxy Syntactic.
