ZJ-8000两个部分硅结构性密封胶对

Description ZJ-8000 Silicone Structural Sealant is a two-part, neutral curing silicone formulation specifically developed for the structural bonding of glass, metal and other building components with good features as follows: 1. Approved by silicone SSG leading group of national committee of economic and trade 2. Meets National standards of GB-16776-2005 3. Excellent adhesion to a wide range of curtain-wall materials such as coated, enameled and reflective glass, anodized oxidation or coated aluminum and stainless steel. 4. High level of mechanical properties with joint movement capability of ±12.5%. 5. Neutral cured, no corrosion, non poisonous 6.Excelent stability in a wide range temperature at -50oC +150oC 7. Excellent weatherproof feature and a high resistance to UV radiation, high temperature and humidity. 8. Lot matching of base and curing agent not necessary. Structural applications require prior testing and written print review by ZHIJIANG. Where to use It is designed for use in structural glazing applications such as: use for structural adhesion and seal the joints of the structural glass and metal in the factory or building site. Curing Neutral alkoxy curing with a little of ethanol to release Properties ZJ-8000 has excellent adhesion without priming to most construction substrates and its typical properties is suitable for wide temperature range. Product could meet GB 16776-2005, ASTM C 1184, ASTM C 920 12.5 CLASS, ISO 11600 12.5E.Typical properties (for reference) Item Base Curing Agent Mixed Base to Curing Agent by Volume Test method Colors White Black Black, no flow paste Specific gravity 1.36 1.03 1.33 Shelf life, month 12 12 Mixed at 12:1 Base to Curing Agent by weight (or 9:1 by volume) Working Time((humidity 50±5%,temperature 23±2oC) minutes 20-60 Tack free time (humidity 50±5%,temperature 23±2oC) minutes 80-100 Corrosive no As Cured 7 Days at (humidity 50±5%,temperature 23±2oC) Ultimate tensile strength MPa 0.95 GB/T113477.8-2002 Ultimate elongation % 120-130 GB/T113477.8-2002 Hardness (Shore A) 40 GB/T1531 Tensile modules at 12.5% elongation MPa 0.14 GB/T113477.8-2002 Please contact zhijiang before make specification.
