~Features:
1.One component,neutralcuring,with excellent adhesion ,weatherability and elasticity for weather sealing in curtain wall and building facades, especially suits applications in the areas with large difference in temperature and low humidity.
2.Good compatibility with other neutral silicone sealants.
3.Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes; virtually unaffected by sunlight, rain, snow and ozone.
4.Remains flexible over a temperature range of -58°F(-50℃) to 302°F(150℃).
5.Extension/compression movement capability of up to ±25percent of the original joint width.
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.Weather sealing in glass curtain wall joints and building facades.
2.Sealing in expansion joints for concrete, plastic and metal etc..
3.Weather sealing in metal, enamel curtain wall joints.
4.Sealing in roof joints and ACP curtain wall joint.
5.Many other applications for movement joint.

Limitations:
1.Can not be used in structural glazing applications or where the sealant is intended as an adhesive.
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.Can not apply to the place where movement capability greater than ±25% of the original joint width.
6.Is not suitable for the place of continuous immersion or year-round moisture.
7.Surface temperature is not below 0℃ or above 50 ℃.
8.Can not ontact with strong acids or bases.
9.Hasn’t performed adhesion and compatibility tests on project substrates and all accompanying accessories.
10.Not to copper, zinc or lead coated surfaces.

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  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: WP236weather proofing 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.

Emergent Treatment:
Keep out of reach of children. Once it contacts skin or eye by accident, rinse the affected part with water for 15 minutes or turn to doctor for help immediately.

Shelf Life:
12 months from the manufacture date stored in cool & dry place below 27 ℃.

Color:

Clear, black, white, gray, other colours as clients’requirement.

Packing/ Mix Ratio:

Packing  A component:185L,B component:18.5L;A component:18.5L,B component:300ml*7. Mix Ratio by Volume  A:B = 10:1.
