1. The weatherability and UV resistance of the sealant is excellent, with a much longer expected service life than other organic sealants in the market. 
2. 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. 
3. Besides, the formula is also free of silicone oil, minimizing oil-staining or other building aesthetic issues caused by the migration of silicone oil. 
4. NON-STAINING! AS-4002 has passed ASTM C1248, the standard test method for staining of a porous substrate by joint sealants. 
5. Green product – It complies with Leadership in Energy and Environmental Design (LEED) v4.1 EQ Credit: Low-Emitting Materials.
6. It also can adhere well to numerous substrates without a primer, is fast-curing, paintable with common water-based coatings.

Unlike polyurethane sealants, this sealant is free of isocyanate and solvent, and thus no issues like blistering or shrinkage will occur. 

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 / Aluminium to concrete wall), both painted and non-painted surfaces. 

Other recommended applications include sealing of masonry, brickworks, anodized aluminium, stainless steel, porcelain, finished wood, coated metal, epoxy and polyester panels, uPVC, polystyrene, and many difficult substrates.
