Premier MS Construction Sealant/Adhesive

ALSEAL Premier Construction Sealant is a one-component, elastomeric joint sealant formulated with MS Polymer of the premium grade. The weatherability and UV resistance of the sealant is excellent, with a much longer expected service life than other organic sealants in the market. The finishing is matt, less tacky, and with low electrostatic charge, thereby reducing fluid streaking issues on façade cladding caused by air-borne dust particles. Besides, the formula is also free of silicone oil, minimizing oil-staining or other building aesthetic issues caused by the migration of silicone oil. It has passed ASTM C1248, the standard test method for staining of a porous substrate by joint sealants. Unlike polyurethane sealants, this sealant is free of isocyanate and solvent, and thus no issues like blistering or shrinkage will occur. It also can adhere well to numerous substrates without a primer, is fast-curing, paintable with common water-based coatings, and it is a green building product that complies with Leadership in Energy and Environmental Design (LEED) v4.1 EQ Credit: Low-Emitting Materials.

Specially formulated to seal metal (e.g. ACP) and stone (e.g. marble) façade cladding due to its excellent
weather ability and non-staining/ less dirt-streaking characteristics. It is also recommended for sealing
concrete joints like precast wall panel joints construction joints, control joints, expansion joints, and window
frame perimeter sealing (PVC / Aluminum to concrete wall), both painted and non-painted surfaces. Other
recommended applications include sealing of masonry, brickworks, anodized aluminum, stainless steel,
porcelain, finished wood, coated metal, epoxy and polyester panels, uPVC, polystyrene, and many difficult
substrates.
