Flexible Construction Joint Sealant-Adhesive


ALSEAL AS-4001 is a single-component, high-performance hybrid sealant based on advanced MS Polymer technology. It is formulated to meet the stringent requirements of various joint sealing applications.
Unlike Polyurethane sealants, its weathering resistance property is much better, therefore it has a longer service life. Flexible Construction Joint Sealant-Adhesive AS-4001 is solvent-less and isocyanate-free formulation ensures that the cured sealant will not shrink or have bubbling issues. It is free of silicone oil, minimizing building aesthetic issues caused by oil-staining and dirt-streaking problems often associated with silicone sealants. The adhesion of the sealant on a wide variety of substrates is great, and it is paintable with most types of common industrial paints.


Flexible Construction Joint Sealant-Adhesive ALSEAL AS-4001 recommended for sealing concrete joints like precast wall panel joints, expansion joints, control joints, connection joints, etc. It is ideal for window frame perimeter sealing. Especially when the sealant needs to be painted. Other recommended applications include sealing of GRC panel systems, anodized aluminum, masonry, porcelain, coated metal, finished wood, epoxy and polyester panels, UPVC, 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.


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


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
