BONDTIE


The BONDTIE uses the PVC outer leaf expander of the Fastie with an inner leaf fixing designed for use with resin materials. Bondties are used widely for applications where the inner leaf is of weaker, softer or perforated materials and the outer leaf is soft brick or block.
The Bondtie is manufactured from A2, 300 series austenitic stainless steel with the inner leaf fixing threaded for setting in SPIT C-Mix Plus resin.This stable resin does not contract or dry out and is supplied in 380ml cartridges for hand application with an applicator gun.After setting of the resin, the inner leaf connection can be tested for pull out load, prior to setting the outer leaf expander.

RESIN CURE TIMES
38 MINUTES AT 25°C
80 MINUTES AT 10°C

TECHNICAL INFORMATION

  

APPLICATION METHOD

SPECIFICATIONS:
Material A2, 300 series, Austenitic Stainless Steel Expanders 12mm diameter PVC to BS2848
The PVC resists chemical attack and is impervious to mould growth, drying or shrinking
Thread diameter of Rod M6
ACCESSORIES:
FT5HS Hex Setting Tool TBIOO Fixed Head Torque Wrench DTE lA/lO Delivery Tube BOPI Hand Air Pump BRHG Resin hand gun TORQUE SETTING:
6.8Nm (51b.ft)

 

DRILL
Drill 12mm diameter hole in brickwork within 10° upwards, setting depth gauge on drilling machine to give 60mm minimum hole depth in inner leaf.
BLOW OUT
Blowing out hole is critical to allow resin to key in and bond to surface of the hole.
RESIN INNER
Apply BRC3 resin to inner leaf with extended tube DTEIA/ 10 attached to nozzel, slowley withdrawing nozzle until it is clear of the inner leaf. Insert Tie. Allow time for resin to set before setting outer expander.

SET OUTER
Fit hex setting tool (FT5HS) on to torque wrench and set outer expander by tightening nut until pre-set torque is reached. Seal outer brick with colour matching mortar.
