Technical Information

Application

Application Information

Mixing Ratio

Component A : Component B = 2:1 by volume

Pot Life

Approximately 25 minutes (60 gram mass)

Consumption

Coverage

1 cartridge yields approximately 10.7-11.0 cu. in. (175-180 ml) of usable epoxy resin.

Application Steps

SUBSTRATE PREPARATION

Surface must be clean, dry and sound. Remove dust from crack by brushing or by blowing clean with oil free compressed air.

MIXING

Cartridge Set-Up: Remove twist-cap and port plug from top of cartridge. Press one of enclosed “flow restrictors” into opening. Insert one of the enclosed static mixers through twist-cap and attach to threading. Insert Sikadur® Crack Fix cartridge into good quality caulking gun. Point upward during initial squeeze of gun’s trigger to purge any entrapped air. As mixed resin approaches end of mixer, discard rest of initial squeeze and portion of next squeeze to ensure uniform blend of adhesive components.
