SIKABIRESIN CF234

Main features

  • 24-part hardener weight ratio
  • 0.43 g/cm3 Part B density
  • Honeycomb edge-fill system hardener

Product Description

SikaBiresin CF234 Part B Hardener is the green amine paste component for the two-part CF230/CF234 epoxy edge-filling system. It is mixed with CF230 Part A at 24 parts hardener to 100 parts resin by weight. Part B has a typical specific gravity of 0.43 at 25 deg C; the combined material has a typical 11-minute pot life at the same temperature. The system forms a lightweight, smooth paste for honeycomb edge filling, cell densification around inserts, and localized sandwich-panel repairs. Final mechanical, thermal, flame-test, shrinkage, and machinability data apply only after CF234 is combined and cured with the specified CF230 Part A resin.

Key features

  • Controlled hardener ratio: Use 24 parts CF234 to 100 parts CF230 by weight
  • Low-density Part B: The green amine paste has a typical specific gravity of 0.43 at 25 deg C
  • Short mixed pot life: The 116 g CF230/CF234 mixture has an 11-minute pot life at 25 deg C

Applications

Edge filling of aluminum and other honeycomb sandwich structures; core-cell densification for insert anchoring; localized sandwich-panel repairs.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
