“ALSEAL” AS-4001 MS Construction Sealant has been tested by an ISO/IEC 17025 accredited independent third-party testing lab according to the 21 CFR 175.300 - Resinous and polymeric coatings. This is a regulation covering most types of adhesives and coatings used on food-contact surfaces. Said regulation also covers certain specific polymers, pigments, additives and the maximum percentage of certain materials in a formulation. It should also be known that the Food and Drugs Administration (FDA) does not approve or endorse any coatings or adhesive to be used for food-contact surfaces. The coating or adhesive to be used for these surfaces shall be tested according to the testing conditions specified in 21 CFR 175.300.

Recommended for sealing concrete joints like precast wall panel joints, expansion joints, control joints, connection joints, etc. It is also ideal for window frame perimeter sealing especially when the sealant needs to be painted. Other recommended applications include sealing of GRC panel systems, anodized aluminium, masonry, porcelain, coated metal, finished wood, epoxy and polyester panels, UPVC, polystyrene, and stainless steel.

AS-4001 MS Construction Sealant contributing to Leadership in Energy and Environmental Design (LEED) v4.1 credit. The EQ Credit: Low-Emitting Materials requires 75 % of adhesives and sealants to meet the volatile organic compound (VOC) emissions evaluation and 100 % of adhesives and sealants to meet the VOC content evaluation. For VOC emissions, the product is to be tested as per the California Department of Public Health (CDPH) Standard Method v1.2-2017. The product must comply with the VOC allowable concentration listed in Table 4-1 of the standard method. The total VOC (TVOC) after 14 days is required to be reported in ranges as specified in the standard method.

ALSEAL MS Construction Sealant 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 longer service lifetime. Also, its solvent-less and isocyanate-free formulation ensures that the cured sealant will not shrink or have bubbling issues. It is also free of silicone oil, minimising 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.
