Description
Flexible Construction Joint Sealant-Adhesive
Description
ALSEAL MS Construction Sealant is a one-component, high-performance hybrid sealant based on advanced MS Polymer technology. Its formula is designed to meet the stringent requirements of various joint sealing applications.
Unlike polyurethane sealants, its weather resistance is much better, so it has a longer service life. In addition, its solvent-free and isocyanate-free formula ensures that the cured sealant will not shrink or have bubbling problems. It also contains no silicone oil, minimizing the building aesthetic problems caused by the oil stains and streaks of dirt often associated with silicone sealants. The sealant’s adhesion to a wide range of substrates is excellent and it can be painted with most types of common industrial paints.
Applications
MS Polymer Base Sealant is recommended by leading architects, civil engineers, and designers for sealing concrete joints such as precast wall panel joints, expansion joints, control joints, butt joints, etc. It is also great for sealing perimeter window frames, especially when the sealant needs to be painted. Other recommended applications include sealing GRC panel systems, anodized aluminum, masonry, porcelain, coated metal, wood trim, epoxy and polyester panels, PVC, polystyrene and stainless steel.

Clean Up
Wet sealants can be cleaned up with acetone or mineral spirits.
Cured sealants can only be removed mechanically.
Joint Design
Joint dimension should be designed by taking into consideration the movement capability of the sealant
and the anticipated joint movement
Generally, the joint width-to-depth ratio is 2:1 for joint width ≥12 mm, or 1:1 for joint width <12 mm
Joint width: minimum = 6 mm, maximum = 35 mm *
Joint depth: minimum = 6 mm, maximum = 12 mm
* Sealing joints with larger joint width is possible but sealant may sag in vertical applications.
Coverage
Width Depth Coverage Coverage
290ml* 600ml*
6mm 6mm 7.32 meter 15.15 meter
10mm 10mm 2.64 meter 5.45 meter
20mm 10mm 1.32 meter 2.73 meter
25mm 12mm 0.88 meter 1.82 meter
* The coverage figures shown above are approximate lineal meter run based on 10% wastage assumption.
Actual coverage may vary.
¨ Calculation formula:
X / [(Y x Z) x 1.1] = Coverage
X = volume of cartridge (or sausage) in ml,
Y = joint width in cm, Z = joint depth in cm,
1.1 = 10% wastage assumption,
Coverage = lineal meter run in cm per cartridge
Limitation
Not recommended for the following applications:
Below waterline or permanent water immersion.
Outdoor sealing/bonding adjacent to glass substrates.
Polyethylene, polypropylene, polytetrafluoroethylene (Teflon), neoprene, and bituminous surfaces.
Overcoated with:
Alkyd resin paint – cure inhibition to the paint
Chlorinated paint – staining issue
Oil based paint – not compatible
