• Good mechanical properties, tensile strength, elongation and resilience. 

• Pliable and flexible.

• Heat stable, does not melt at high temperature up to 60 ^oC.

• Excellent adhesion; strong durable bond.

• Economical.

• Time saving, Single component, does not require mixing, thereby saves time.

• Oxidation resistant and durable.

APPLICATION

Surface Preparation
JOINTSEAL-C is applied by trowel, putty knife or standard sealant gun or pressure equipment. The sealant should be applied flush with the surface.

Joint Dimension
Ideally the depth of the joint should be half the width. Horizontal joints deeper than 10 mm should be first filled with sand backer rod, fiber board fillet to a depth of 10 mm form the surface. Vertical joints should be filled with back rod, fiber board filler or other suitable filler to a depth of 10 mm from the surface. Do not use polystyrene or polyurethane backer rod. 

DESCRIPTION
JOINTSEAL-C. is a high quality, economy grade, cold applied, elastomeric modified bitumen compound.

The fiber board or backer rod can be adhered to the joint wall with this application of JOINTSEAL-C. The backer rod or other filler material is desirable to equalize the compression of the sealant induced by joint movement and to reduce the thickness of the sealant. On traffic bearing surfaces, the sealant should be slightly sanded to prevent sticking.

Sealant Thickness
Maximum sealant thickness should be 10mm.  It is recommended that the application takes place in two stages of 5 mm each, allowing 4-8 hours of curing time between each application in order to expedite curing and minimize shrinkage cracking.

CLEANING
Tools : Clean with kerosene
Hands : Use a hand cleaner or kerosene followed by soap and water.

PACKING
