Sikadur-33
Sikadur-33 is a two-component, 100% solids, moisture-tolerant high-modulus structural epoxy smooth-paste adhesive with a very rapid cure. This 2 gallon unit (part 105311) mixes 1:1 by volume, holds a pot life of approximately 15 minutes, and seals cracks and injection ports ahead of pressure injection. At 73 F it reaches approximately 5,600 psi compressive in 1 hour and approximately 8,600 psi at 1 day. It conforms to ASTM C-881 Types I and II, Grade 3, Class B/C except for gel time.
