Sika SikaWrap Hex 230C
SikaWrap Hex-230 C is a unidirectional carbon fiber fabric in a 12 in x 150 ft roll for structural strengthening. It field-laminates with Sikadur epoxy for shear, confinement, and flexural CFRP work in confined spaces.
- Unidirectional carbon fiber fabric, 6.7 oz per sq yd
- Lightweight fabric for confined spaces
- ICC ESR-3288 evaluated FRP system
SikaWrap Hex-230 C
SikaWrap Hex-230 C is a unidirectional carbon fiber fabric field-laminated with Sikadur 300, Sikadur Hex 300/306, or Sikadur 330 to form a CFRP strengthening system. This 12 in x 150 ft roll is a lightweight 6.7 oz per sq yd fabric for confined spaces; for a heavier unidirectional option, see SikaWrap Hex-117 C. ICC ESR-3288 covers the system, and wet or dry lay-up both work for shear, confinement, and flexural strengthening.
