NOTE
If parts cannot be separated, work folded medium-grit sandpaper or section of
steel hacksaw blade between two surfaces to remove old adhesive.
IF REBONDING JOINT THAT HAS SEPARATED OR REPLACING DAMAGED PART, COMPLETELY
SEPARATE PART OR PARTS USING HEAT GUN AND PUTTY KNIFE. REMOVE AS MUCH OF OLD
ADHESIVE AS POSSIBLE. HEAT GUN WILL SOFTEN ADHESIVE AND ALLOW IT TO BE PEELED
OFF SMC.
SCUFF SURFACES WITH 100-220 GRIT SANDPAPER.
CLEAN SURFACES TO BE BONDED WITH ASHLAND 6036 PRIMER OR METHYLENE CHLORIDE.
INSPECT AREA CLOSELY TO BE SURE ALL OLD ADHESIVE IS REMOVED.
IF REPLACING LARGE PART, SUCH AS FENDER, ALINE PART ON HOOD AND CLAMP IN PLACE.
DRILL HOLE THRU BONDING SURFACES (19) AND INSTALL CLAMPING BOLT (20) IN HOLE.
INSTALL TWO WASHERS (21), ONE ON EACH BONDING SURFACE (19). INSTALL NUT (22) ON
CLAMPING BOLT (20). THERE SHOULD BE ENOUGH CLAMPING BOLTS (20) TO HOLD HOOD IN
PLACE AND KEEP BONDING SURFACES (19) TOGETHER, ONE BOLT EVERY 12-18 IN. (30-45
cm). REMOVE PART FOR APPLICATION OF ADHESIVE.
USING MANUFACTURER’S INSTRUCTIONS, MIX ENOUGH ASHLAND PLIOGRIP 6600/6622
ADHESIVE TO BOND PARTS TOGETHER ABOUT 3/8-lN. (l0-mm) DIAMETER BEAD AT BONDING
SURFACE (19). ADHESIVE WILL CURE IN 7-10 MINUTES.
PUT ADHESIVE IN STANDARD CAULKING GUN AND CUT NOZZLE SO 3/8 IN. (10-mm) DIAMETER
BEAD CAN BE DISPENSED. IF PARTS COULD NOT BE COMPLETELY SEPARATED, CUT NOZZLE
SO ADHESIVE CAN BE INJECTED BETWEEN SURFACES.
DISPENSE 3/8-lN. (10-mm) DIAMETER BEAD OF ADHESIVE BETWEEN ALL BONDING SURFACES
(19).
WITHIN 5 MINUTES OF DISPENSING ADHESIVE BEAD, ALINE PART ON HOOD AND CLAMP
FIRMLY IN PLACE. IF A LARGE PART (FENDER, FOR EXAMPLE), INSTALL CLAMPING BOLTS.
TIGHTEN CLAMPS OR CLAMPING BOLTS JUST ENOUGH TO ENSURE UNIFORM AMOUNT OF
PRESSURE IS APPLIED ALONG SEAM. IDEALLY, ADHESIVE SHOULD BE COMPRESSED TO
FORM BONDLINE 1 IN. (25 mm) WIDE AND 0.030 IN. (0.76 mm) THICK.
BEFORE ADHESIVE CURES, REMOVE EXCESS ADHESIVE THAT SQUEEZES OUT EDGES OF
BOND.
BOND WILL BE SECURE IN ABOUT 1 HOUR. REMOVE CLAMPS.
IF HOLES WERE DRILLED FOR CLAMPING BOLTS, REPAIR HOLES USING INSTRUCTIONS IN
CRACK OR SMALL HOLE REPAIR, ABOVE.
