ELB-338 Epoxy Tooling Compound Bond Coat (room-temp), was developed to compliment the fabrication of a composite tool utilizing ADTECH EL-323 TC Room Temp Tooling Compound. The blue resin base when combined with the yellow hardener and thoroughly mixed will turn green. ELB-338 when mixed (100R/50H) has a heavy, creamy, thixotropic consistency. ELB-338 will eliminate the time consuming preparation of blending pre-catalyzed Laminating Resin with pre-catalyzed EL-323 TC Tooling Compound for bond coat application to primary laminate.
