硅酮耐候密封胶硅酮耐候密封胶的主要技术指标中，表征施工性能的有下垂度、挤出性、表干时间，表征固化后耐候胶性能的主要是位移能力和质量损失率。耐候胶的质量损失率与结构胶的热失重相当，主要考察耐候胶在长期使用后的性能变化情况，质量损失率越高，长期使用后性能下降越严重。硅酮耐候密封胶的主要作用是对板块间接缝的密封，由于板块经常会受到温度变化、主体结构变形等影响而发生位移，导致接缝宽度也就会随之发生变化。这就要求耐候胶具有良好的承受接缝位移的能力，在长期承受接缝宽度变化的情况下不发生开裂，这一性能称为耐候胶的位移能力，与结构胶的“变位承受能力”不同。

The main technical indexes of silicone weatherproof sealant silicone weatherproof sealant, characterization of the construction performance of sagging, extrusion, surface drying time, characterization of the cured sealant is mainly displacement capacity and mass loss rate. The mass loss rate of weather resistant adhesive is similar to that of structural adhesive. The performance changes of weather resistant adhesive after long-term use are mainly investigated. The higher the mass loss rate is, the more serious the performance degradation will be after long-term use. The main function of silicone weatherproof sealant is sealed to the plate joint, due to the effect of plate is often affected by temperature changes, the main structural deformation and displacement, leading to joint width will be changed. This requires the sealant has good bearing joint displacement, in a long-term bear joint width changes without cracking, this performance is called the displacement ability of sealant, adhesive and structure of the displacement capacity of different.

硅酮结构密封胶硅酮结构密封胶一种单组份、中性固化、专为建筑幕墙中的玻璃结构粘结装配而设计的。可在很宽的气温条件下轻易地挤出使用。依靠空气中的水分固化成优异、耐用的高模量、高弹性的硅酮橡胶。产品对玻璃不需用底涂，能产生优越的粘结性。结构胶指强度高（压缩强度>65MPa，钢-钢正拉粘接强度>30MPa，抗剪强度>18MPa），能承受较大荷载，且耐老化、耐疲劳、耐腐蚀，在预期寿命内性能稳定，适用于承受强力的结构件粘接。非结构胶强度较低、耐久性差，只能由于普通、临时性质的粘接、密封、固定，不能用于结构件粘接。建筑工程使用年限一般在50年以上，构件承受较大复杂应力，直接关系人员的生命、财产安全，粘接胶种应采用结构胶。结构胶在工程中结构胶应用广泛，主要用于构件的加固、锚固、粘接、修补等；如粘钢，粘碳纤维，植筋，裂缝补强、密封，孔洞修补、道钉粘贴、表面防护、混凝土粘接等。

Structural silicone sealant structural silicone sealant for one component, neutral curing, designed for bonding glass structure assembly in building curtain wall design. It can be easily squeezed out in a wide range of temperatures. Rely on moisture in the air to solidify into excellent, durable, high modulus, high elasticity silicone rubber. The product does not need bottom coating for glass, and can produce superior cohesiveness. The structure of the rubber finger high strength (compressive strength of >65MPa steel, steel tensile shear strength of the bonding strength of >30MPa, >18MPa), can withstand the big load, and aging resistance, fatigue resistance, corrosion resistance, stable performance in the life expectancy, suitable for bearing structure adhesive strength. Non structural adhesive has low strength and poor durability. It can only be bonded, sealed and fixed because of ordinary and temporary properties, and it can not be used for structural parts bonding. The service life of building engineering is generally more than 50 years, and the component is subjected to more complex stress, which directly relates to the life and property safety of the personnel, and the structural adhesive should be used for the adhesive glue. The structure of structural adhesive adhesive is widely used in engineering, the main component for reinforcement, anchoring, bonding and repairing; such as steel, sticky carbon fiber reinforcement, anchorage, cracks, sealing, hole repairing, spike paste, surface protection and concrete bonding etc..

单组份硅酮玻璃胶是一种类似软膏，一旦接触空气中的水分就会固化成一种坚韧的橡胶类固体的材料。硅酮玻璃胶的粘接力强，拉伸强度大，同时又具有耐候性、抗振性，和防潮、抗臭气和适应冷热变化大的特点。加之其较广泛的适用性，能实现大多数建材产品之间的粘合，因此应用价值非常大。

One component silicone sealant is a kind of ointment, once exposed to moisture in the air will be solidified into a tough rubber solid material. Silicone glass adhesive has strong adhesion, high tensile strength, and weather resistance, vibration resistance, moisture resistance, anti odor and adapt to the characteristics of large changes in cold and hot. In addition to its extensive applicability, it can achieve the adhesion between most building materials products, so the application value is very large.
