FT-2000 Weatherproofing Silicone Sealant

Description FT-2000 Weatherproofing Silicone sealant is a one-part, neutral-cure, architectural grade sealant specifically designed for general glazing and weather sealing in curtain wall and building facade. It easily extrudes in a wide rang weather condition and quickly cures at room temperature by reaction with moisture in the air to form a excellent , durable, flexible silicone rubber seal. Characteristic a. Can be easily used and extruded any time. b. Neutral cure-suitable for use on most construction materials. c. Excellent adhesion to most construction materials without the primmer. d. Excellent weather ability, virtually unaffected by sunlight, rain, snow, ozone or temperature extremes. e. Low modulus sealant. f. Extension/compression movement capability of up to ±50% of the original joint width. Where to use FT-2000 is especially designed for general glazing and weather sealing in curtain wall and building facades. It is suitable for glazing weatherproofing movement joint and sealing the joints of the non-structural curtain wall. It can form a waterproofing sealed layer to many kinds of glasses, coated aluminum, decorative metal board, tile, and granite without primmer. Use limitations FT-2000 silicone Weatherproofing sealant is not fit for structural usage. It should NOT be applied in the following conditions: a. To building materials that bleed oils, plasticizers or solvents and green or partially sulfur zed gaskets or tapes, etc. b. In totally confined spaces (Silicon sealant need the water in the air to cure) c. For continuous inversion in water or below-grade applications all the year d. To painted surfaces, may cause seal failure as the paint cracking or paint stripping e. To frost-laden or wet surfaces f. Surface touch the food directly g. Easily suffer mechanical wear h. Fireproofing seal system Material feature FT-2000 Silicone Weatherproof sealant can keep good viscous degree and can easily extruded at -25℃ to 50℃; Can keep good flexibility at -50℃ to 150℃ after cured. It is unaffected by UV ray, rain, ice, snow, air pollution, ozone and high or low temperature. Even under the severe weather conditions, it can maintain excellent weatherproofing and waterproofing properties for some years, FT-2000 has an excellent compatibility with reflect glass, doubling glass, silicone hollow glass, acrylic acid, polythene and etc. Colors FT-2000 weatherproof silicone sealant is available 4 standard colors: white, black, grey, clear. We can also supply the other color according to the customer's requirement. Packing It is available in 300ml plastic cartridges, 24 cartridges/ carton. or 500ml aluminum sausages,20 sausages /carton. Storage and usable life It has a useable life of 12 months from the produced date when stored under dry and airy,27℃ or lower temperature conditions in the original unopened container. Application method Install backing material or joint fillers. Set blocks, shims and tapes. Cut the nozzle of FT-2000 and fit into gun and make extrusion diameter fit for joint. Continuous extrude sealant into joint without air forming. Care must be taken to ensure complete fill of the sealant cavity. Tool the sealant with light pressure before a skin begins to form. Make sealant surface a sunken shape using raised tool. Not use soap water for assistant. Remove the masking tape after tooling. The sealant for bottom joints should be tooled into slope to protect water accumulation. The surface of sealant should be dry and frost-free. The uncured sealant is not permitted to contact with polished granite, metal or glass to preventing a thin film formed on the substrate surface to affect the esthetic things. Use masking tape. If sealant contact with non-porous material, clean out with methyl ethyl ketone, tolune or xylene.
