| Description
Green MS Sealant is a single-component, paintable elastomeric hybrid sealant that is based on advanced MS Polymer technology. The white colour of AS-4005 meets the requirements of CSM (Cleanroom Suitable Materials) standard, hence it is recommended for applications in electronics cleanrooms. Unlike Polyurethane sealants, its solvent-less and isocyanate-free content guarantees no sealant shrinkage and bubbling issues. It is also free of silicone oil, minimizing building aesthetic issues caused by oil-staining and dirt-streaking problems often associated with silicone sealants.
| Features
- Cleanroom Suitable Material (CSM) ISO-ACCm Class -7.1 qualification. (White only)
- Good UV resistance
- Paintable
- Low static charge – Less dirt streaking
- No silicone oil – Non-staining on adjacent
- substrates
- No isocyanate – No blistering
- No solvent – No shrinkage
- Bonds most substrates without primer
| Application
Sealing concrete joints (precast wall panels, expansion joints, control joints, FRC boards, etc.), window frame perimeter, etc. Other applications include sealing of anodized aluminum, masonry, porcelain, coated metal, finished wood, epoxy and polyester panels, UPVC, polystyrene, and stainless steel. AS-4005 (White) suitable for Electronics Cleanroom application.
