Product Details
The specified sealant bead size should be calculated
The specified sealant bead size should be calculated to comply with the compression and extension capabilities of the sealant in relation to the anticipated joint width due to expansion and contraction.
Generally calculation of the width of ESCOSIL 2525
Generally calculation of the width of ESCOSIL 2525 should be computed on the basis of a maximum +50% compression and extension capability; minimum bead size should not be less than 3mm to accommodate movement. Design joint depth of which ratio width becomes 0.5 to 1. Suitable joint (Depth vs Width)
- Joint size minimum 6mmx6mm
- Joint size maximum 30mm.
