M628 neutral general purpose silicone sealant

Features:
1.One component,neutral curing,non-corrosive to metal, coated glass, marble etc.
2.Prime-less adhesion to most building materials.
3.Remains flexible over a temperature range of -58°F(-50℃) to 302°F(150℃).
4.Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes.
5.Good compatibility with other neutral silicone sealants.
6.The material is supplied as a paste, which cures into extremely tough elastomeric silicone rubber ensuring a durable, flexible, watertight bond upon exposure to atmospheric moisture.

Main applications:
1.Sealing in joints.
2.Glazing for door and window.
3.Various interior decoration glass, aluminum, ceramic, tile, wood and metal, etc.
4.Many other uses.

Limitations:
1.Can not be used in structural glazing applications.
2.Is not appropriate for all will be leaking oil, plasticizer or solvent surface.
3.Is not suitable for airtight place, because the silicone sealant need absorb air gas in the water cure.
4.Not for frost or wet surface.
5.Is not suitable for the place of continuous immersion or year-round moisture.
6.Surface temperature is not below 0℃ or above 50 ℃.
7.Can not contact with strong acids or bases.
8.Cannot be used on joint which bearing structural strength or places of physical damage.
9.Hasn’t performed adhesion and compatibility tests on project substrates and all accompanying accessories.

Installation:
1.Surface preparation: Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application.Using proper materials and cleaning procedures is vital for sealant adhesion.
2.Cleaning materials:clean, fresh solvent; clean, white cloths free of lint or other lint-free wiping materials; primer (when required).
3.Cleaning procedures:Remove all loose material (such as dirt and dust), plus any oil, frost or other contaminants from the substrates to which the sealant will be adhered. Do not use detergent to clean the substrate as residue may be left on the surface. Wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface before it evaporates. Change the cleaning rags frequently, as they become soiled. If cleaned areas are again exposed to rain or contaminants, the surface must be cleaned again.
4.Primers: M628 neutral general purpose silicone sealant will bond to many clean surfaces without the aid of a primer. For difficult-to-bond substrates, the use of a primer or special surface preparation should be evaluated.
