Supex 488 Neutral cure Sealant – Product Description
Neutral cure sealant, Supex 488 is a one-component, high-performance sealant based on advanced MS Polymer technology. This sealant is free of solvent, silicone and isocyanate. Its features includes fast-drying speed and excellent UV, weather and temperature resistance. The adhesion on various substrates is excellent even without the use of primer, and the sealant is paintable with most types of common industrial paints.
Multipurpose Neutral Cure Sealant
Supex 488 multipurpose adhesive & sealant is a gun-grade, one component sealant based on silane modified polymer, which cures by reaction with moisture to an elastic product. The skin formation and curing times are dependent on humidity and temperature, and the curing time also depends on joint depth. By increasing the temperature and moisture curing time can be reduced. Low temperature & low moisture retard the process. Supex 488 is free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion to many substrates and is compatible with suitable paint systems. The sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications.

Uses of Neutral cure sealant, Supex 488
Ideal for making permanent elastic seals of high bonding strength, especially interior and exterior auto body seams and joints. It is also suitable for high-performance, elastic bonding in construction and industrial applications.
Bus body adhesives & sealants is suitable for mounting and pasting of materials such as metal, aluminum, glass, plastic, wood and concrete with each other. It can be used for construction industry, both indoors and outdoors as an elastic adhesive
How to use Supex 488 MS polymer Sealant
1. Surfaces must be clean, dry and free of dirt, grease, oil or water.
2. Surfaces should be cleaned with alcohol, M.E.K. or other suitable solvent. Do not use soap or detergent.
3. For a neat finishing, apply masking tape and remove it before sealant skins over.
4. Cut the tip off and puncture the internal foil seal with the nozzle. Cut the nozzle at 45° angle to desired bead-width and apply the sealant to substrate with a cartridge gun.
5. Tool the sealant within 15 minutes of extrusion before it skins. Tack-free in 30 minutes.
6. Uncured sealant can be cleaned up with mineral spirits.

Advantages of Supex 488
- Bonds almost all substrates including sheet metal, aluminium, FRP, composite, concrete, glass, wood etc, except PP, LDPE, HDPE, Telfon.
- provides high strength, flexibility so very important in automobile body fabrication. absorbs shock and vibrations
- VOC free
- works on moist surface and underwater too
- faster production due to faster tack free time than PU sealants.
