With the spring half, the next weather will be more and more hot, with the temperature continues to rise, the humidity in the air continues to increase, will have an impact on the curing of glass sealant products, because the curing of sealant needs to rely on the moisture in the air, so the temperature in the environment, humidity changes will have a greater impact on the use of Silicone Sealant such products. 
In the manufacture of insulating glass, silicone sealant needs to be completely cured before it can fully play its structural and air tightness. However, with the increase of temperature, the surface drying time of the sealant will be shortened, and the deep curing speed will be accelerated, and this series of changes caused by temperature changes are likely to have an adverse impact on the construction of the sealant and the performance of the characteristics, so in the high temperature period, special attention needs to be paid to the construction of the silicone rubber, so as not to cause the loss of functional characteristics. In the construction, pay extra attention to the following conditions Bubbles are formed after construction Sometimes after gluing, there will be some large and small bubbles above the glue seam, and the inside is hollow after cutting, and the bubble situation of the sealant will lead to the structural viscosity of the sealant will decrease, and the sealing effect will be greatly reduced. Why do bubbles appear? That is because the methanol contained in the curing process of alcohol glue will release gas, generally methanol will begin to volatilize at about 50 ° C, and when the temperature rises, especially when the sun is direct, the release speed will be accelerated. General construction environment in concrete, metal window structure, poor permeability, surface dry curing fast, solidified rubber strip will appear on the size of the bubble. Therefore, when the temperature is relatively high, if the alcohol sealant is used, try to avoid direct sunlight construction, or carry out cooling treatment measures. In addition, in the summer, there is more rain, and the air humidity is large, so do not glue before the substrate and glue seam are not dry, and we must wait until they are completely dry before carrying out construction. The surface is dry and the pulling time is too fast, which affects the dressing and use of sealant After the temperature and humidity of single-component silicone or two-component Silicone Adhesive is increased, the surface drying time (single-component silicone adhesive) and the breaking time (two-component silicone adhesive) will be shortened. Therefore, when the temperature is high, for single-component silicone glue, the surface drying time needs to be tested before use, and the surface drying time of the product in the current use environment needs to be mastered in advance, which can be used to guide the control of time in the construction and guide the actual dressing and gluing work
