Joint Construction Sealant
Joint Construction Sealant
AS-4001
A single-component, moisture-cured elastomeric hybrid sealant based on advanced MS Polymer technology. It offers superior weathering, UV and temperature resistance characteristics. It is a green sealant formulated to meet the low VOC regulation. It is solvent and isocyanate free so does not cause any shrinkage or bubbling. It is also free of silicone oil, hence minimizing building aesthetic issues caused by dirt-streaking as seen with silicone sealants. Its adhesion on various substrates is excellent even without primer, yet it is paintable with most types of industrial paints.
Recommended for sealing concrete joints like wall panel joints, expansion joints, control joints etc. It is also ideal for window frame perimeter sealing especially when the sealant needs to be painted as well as facade cladding designed with metal panels or natural stones. Other recommended applications include sealing of anodized aluminum, masonry, porcelain, coated metal, finished wood, epoxy and polyester panels, UPVC, polystyrene and stainless steel.
Features:
- ASTM C-920 Compliance
- ISO 11600 (F Class 25 LM) compliant
- 50% Movement capability
- Good UV resistance
- Paintable
- Low static charge – Less dirt streaking
