8000 is a one-component, low-modulus, neutral-curing, silicone sealant designed for weather-resistant sealing of various curtain walls (glass curtain walls, aluminum curtain walls, etc.). While meeting the requirements of low modulus applications, the displacement capacity can reach 100/50 grades, and has excellent weather resistance. After artificial accelerated weathering aging test, the physical and chemical properties of the sealant have not changed significantly. Use the glue gun to squeeze the glue from the sealant cylinder into the seams that need to be sealed. The sealant absorbs the moisture in the air at room temperature and solidifies into an elastomer to form an effective seal.
1 Product Features Low modulus, dealcoholization, neutral curing, no corrosion to metal, coated glass and other building materials; The displacement capacity is up to 100/50. This product can maintain the same performance for the normal expansion and shear deformation of the curtain wall; Excellent weathering resistance, aging resistance, UV resistance, ozone resistance, water resistance; Excellent resistance to high and low temperature, it does not become brittle, harden or crack at -50 ℃ after curing, does not soften and degrade at 150 ℃, and maintains good elasticity; Single component, easy to use, good extrudability and thixotropy at 4 ℃ ~ 40 ℃; Excellent adhesion to most building materials; Rhenium has good compatibility with other neutral silicone adhesives.
2 main uses Weather-resistant seal for various glass curtain walls; For weather-resistant sealing of metal (aluminum sheet) and enamel curtain wall; Seal for concrete, metal, etc .; Seam sealing of roof construction; Other multiple uses.
3. Restrictions on use Can't be used as structural sealant; In the case of low humidity (<50% RH) or large temperature difference between day and night (> 15 ℃), the glue seam may bulge, but it will not affect the sealing performance; It should not be used in tightly ventilated places, because the sealant needs to absorb moisture in the air to solidify; When the surface temperature of the material is lower than 4 ℃ or higher than 40 ℃, it is not suitable for construction; Not suitable for frosty or wet surfaces; It should not be used in places with continuous water immersion or wet places all year round; Avoid contact with rubber materials (such as rubber strips, rubber pads, etc.) to avoid yellowing; Avoid contact with acidic or alkaline substances (such as exterior wall cleaning fluid) to avoid discoloration; Should not be used on all materials that will exudate grease, plasticizers or solvents, such as the surface of oil-soaked wood.

5. Quality Assurance
This product has passed ISO9001 management system certification. It strictly produces and controls product quality according to ISO9001 quality system requirements.
6. Maintenance Generally, no maintenance is required. If the sealant seam is broken and the damaged part is replaced, only the accumulated dirt must be removed with a solvent and then filled with the sealant.
7. Safety instructions Before using the product, you should review the product's Safety Data Sheet (MSDS). The sealant product is non-toxic after it is completely cured, but avoid contact with eyes before curing. If contact with eyes, please rinse with plenty of water and seek treatment from doctors;
