Overview:

Junbond^® JB26 is One component, room temperature moisture curing MS Sealant.  It is low modulus, building joint sealant, good weather resistance, good elasticity, no harmful substances will be produced during and after curing, and there will be no pollution to the substrate.

 

Product Feature:
1)Good adhesion to most of substrates withoutprimer.
2)Good weathering and UV resistance.
3)  High flexibility Movement.
4)  Paintable.
5)  Excellent workability.



Main Application:
*1)Flexible jointing for precast panel, wood, metal, marble and PVC joinery seams, curtain wall, bakes clay, concrete roof tiles in constructing area.
2)Expansion joints in building, highway, tunnel, runway, water conservancy project.
3)Expansion jointing for other traditional construction.

How to use:
