YT910硅石天气密封胶检验

YT910 Silicone Stone Weather-proofing Sealant YT910 is extruded from tube with sealant gun when used, and it absorbs the moisture in the air, then cures to elastomer capable of maintaining a seal effectively. 1C haracteristics YT910 belongs to RTV-1 good extrusion and thixotropy between 4 + 40.Easy to use; Neutral curing non-corrosive to metal,coated glass,concrete,marble,granite etc; No inert Iow-molecular-weight components in the formulation like plasticizer and Pollution-free to porous materials like marble, granite. Excellent adhesion to all type marble, granite and cement materials; Release Iow-molecular-weight alcohol and no unpleasant odor during cure; Excellent resistance to weather, UV, ozone, water; Excellent resistance to Iow and high temperature change.No fragility,rigidification or crack at -50, and no softening, degradation at 150 when curd. It always keeps good elasticity; Good compatibility with other neutral silicone sealants. 2Purpose: Weather sealing for stone curtain wall joints and precast slab joints Sealing for concrete expansion joints in tunnel and pavement; Adhesion and sealing in expansion joint for ceramic engineering Joint sealing between stone and other materials like glass, metal,plastics etc; Many other uses. 3.Typical Technology Data: No. PerformanceStandardMeasured valueSingle Evaluate1AppearanceFine and uniform ointment, it shall not have bulb, surface coagulation and gel.Conform standardQualified2Slumpability(mm)Vertical,(mm)≤30QualifiedHorizontalNon distortedNon distorted3Tack-Free Time (h)≤30.5Qualified4Extrusion, (ml/min)≥802.2Qualified5TensileModulus(Mpa)230.4 or 0.60.5/-200.76Permanent set adhesionNon destroyedNon destroyedQualified7Max. strength elongation(%)/281/StabilityStore for 12 months at -20 27 in cool, dry places after date of delivery.4.Application Standard: China standard GB/T14683-2003 Company standard Q/(NGS) YT 1-2005 U.S.A ASTM C 920-01 5.Package: 500ml ham bag 6.Restriction of Usage: Cannot be used as structural sealant; Unsuitable for all kinds of material that can effuse grease, plasticizer or solvent; Unsuitable for the airproof location, because it is required to absorb moisture in air to cure for the sealant; Unsuitable for the frosty or moist surface; Unsuitable for the continually soggy or moist place; Cannot be used if the temperature is below 4 or above 40 on the surface of the materials. 7.Technical Service: Offer the integral technical data the products Adhesion Test: The products of YT910 silicone sealant have excellent adhesion to most common building material, as glass anodized aluminumceramictile granite brickwoodsteel and most plastics. But we cannot ensure our sealants are suitable to all materials, as a result of the unceasing appearance of new building materials and the application of new surface treatment technology. In some cases, it is required to have the adhesion test on the substrates. In the laboratory of our company, we can carry out the adhesion test for clients and give the test report that includes experimental result, recommended products, cleaning methods of the material surface etc. Compatibility Test: If the accessory materials like baker, double-sided glue strip can not be compatible with silicone rubber, it may cause silicone rubber to turn colors, even lose adhesion. To avoid these problems, we provide services of compatibility test for clients. Clients can send the accessory to us by mail (or other ways), then we will carry out the compatibility test and submit the test report. Staining Test: We provide services of pollution test for clients. Clients can send the substrates to us by mail (or other ways),then we will carry out the stainging test and submit the test report. 8. Joint Design and Working Procedure: See also The Technology Instruction of YuanTong Construction Silicone Sealant 9.Safety: Non-toxicity when cured; Avoid eye contact before curing lf happened ,rinse opened eye for several minutes under running water, then consult with a doctor; Keep away from children; Ensure adequate ventilation at workplace or curing area. 10.Maintenance: Generally there needs no repairing. If impaired in sealing joints, clean with proper solvent and repair with our products that can adhere well. Important: The information contained in this instruction is correct. However, by no means can it be considered an absolute guarantee, as usage and application of the product in accordance with the instruction given and their success in application is beyond our control and is dependent on a number of factors. Clients should have a good knowledge of the product and make independent judgments of optimal usage before application.
