& nbsp; & nbsp; What is weather resistant adhesive
  & nbsp; & nbsp; Weathering sealant is a single component, neutral curing silicone sealant specially designed for various curtain wall weather sealing. It has excellent weather resistance and has undergone artificial accelerated climate aging testing, with no significant changes in the physical and chemical properties of the sealant. When in use, use a glue gun to squeeze the glue from the sealant cylinder into the joint that needs to be sealed. The sealant absorbs moisture from the air at room temperature and solidifies into an elastic body, forming a useful seal.
  & nbsp; & nbsp; The benefits of weather resistant adhesive
  & nbsp; & nbsp; 1. Single component, easy to use, with excellent extrusiveness and thixotropy in the temperature range of 4 ℃ to+40 ℃. It can be directly applied by extruding with a glue gun;
  & nbsp; & nbsp; 2. Neutral curing, non corrosive to building materials such as metals, coated glass, concrete, marble, granite, etc., widely used;
  & nbsp; & nbsp; 3. The displacement can only reach level 20. Regarding the normal elasticity and shear deformation of the curtain wall, this product can maintain its function and provide useful sealing effect;
  & nbsp; & nbsp; 4. Weather aging resistance function, resistant to aging, UV rays, ozone, and water;
  & nbsp; & nbsp; 5. Excellent resistance to high and low temperatures, it will not become brittle, harden or crack even at low temperatures of -30 ℃ after curing, and will not soften or degrade at high temperatures of+90 ℃, maintaining excellent elasticity;
  & nbsp; & nbsp; 6. Having adhesive properties, it forms a strong bond with most building materials after curing without the need for a primer;
  & nbsp; & nbsp; 7. Excellent compatibility with other neutral silicone adhesives.
  & nbsp; & nbsp; The use of weather resistant adhesive
  & nbsp; & nbsp; 1. Used for weather resistant sealing of various glass curtain walls;
  & nbsp; & nbsp; 2. Used for weather resistant sealing of metal (aluminum plate) and enamel curtain walls;
  & nbsp; & nbsp; 3. Used for joint sealing of concrete, metal, etc;
  & nbsp; & nbsp; 4. Sealing of roof building joints< br />
  & nbsp; & nbsp; What is structural adhesive
  & nbsp; & nbsp; Structural adhesive is a type of high-strength adhesive (compressive strength>65MPa, steel steel tensile bonding strength>30MPa, shear strength>18MPa)It is an adhesive that can withstand large loads, is resistant to aging, fatigue, and corrosion, and has stable performance within the expected lifespan. It is suitable for bonding strong structural components.
  & nbsp; & nbsp; The benefits of structural adhesive
  & nbsp; & nbsp; 1. Simple application: can be squeezed out and used at any time.
  & nbsp; & nbsp; 2. Neutral curing: Suitable for most building materials without adverse reactions or corrosive effects.
  & nbsp; & nbsp; 3. Good adhesion: No need for primer, can form strong adhesion with most building materials.
  & nbsp; & nbsp; 4. Very good aging resistance and stability.
  & nbsp; & nbsp; 5. After curing, it has high modulus function and can also support interfaces; 25% elastic displacement capability.
  & nbsp; & nbsp; Curing time of structural adhesive
  & nbsp; & nbsp; It can be put into use after curing at 20-25 ℃ for 24 hours or curing at 20-25 ℃ for 2 hours+80 ℃ for 2 hours. If the temperature is low, heating or extending the curing time should be used to promote curing.
  & nbsp; & nbsp; The use of structural adhesive
  & nbsp; & nbsp; Structural adhesive has high strength, peel resistance, impact resistance, and simple construction process. Used for bonding between the same or different materials such as metal, ceramic, plastic, rubber, wood, etc. It can partially replace traditional connection methods such as welding, riveting, and bolted connections. The stress distribution on the joint surface is uniform, and there is no thermal impact or deformation on the parts.
  & nbsp; & nbsp; Structural adhesives are widely used in engineering, primarily for reinforcing, anchoring, bonding, repairing, and other applications of components; Such as bonding steel, bonding carbon fiber, planting reinforcement, crack reinforcement, sealing, hole repair, road nail bonding, surface protection, concrete bonding, etc.
  & nbsp; & nbsp; Difference between weather resistant adhesive and structural adhesive
  & nbsp; & nbsp; 1、 Different uses
  & nbsp; & nbsp; weather proofing sealant
  & nbsp; & nbsp; 1. Suitable for weather resistant sealing of various curtain walls, especially recommended for glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging weather resistant sealing.
  & nbsp; & nbsp; 2. Sealing of joints between metal, glass, aluminum, ceramic tiles, organic glass, and coated glass.
  & nbsp; & nbsp; 3. Sealing of joints on surfaces of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum, and painted aluminum. In most cases, primer is not required.
  & nbsp; & nbsp; structural adhesive
  & nbsp; & nbsp; 1. Mainly used for structural or non structural bonding installation between metal and glass in glass curtain walls.
  & nbsp; & nbsp; 2. It can directly connect glass with the surface of metal components to form a single installation component, meeting the requirements of curtain wall planning for fully concealed or semi concealed frames.
  & nbsp; & nbsp; 3. Structural bonding and sealing of insulating glass.
  & nbsp; & nbsp; 2、 Effect locally
  & nbsp; & nbsp; Weathering sealant is primarily used for sealing and filling joints between materials, as well as waterproof sealing of seams; Structural adhesive is primarily used for bonding structural and non structural installations of various curtain walls, and the effects of the two differ locally.
  & nbsp; & nbsp; 3、 Adhesive function
  & nbsp; & nbsp; 1. Weathering sealant can also be said to be a universal adhesive, primarily with resistance to extreme weather conditions such as ultraviolet radiation, acid rain, and snow. The displacement ability of weather resistant adhesive (which can be used as an elastic explanation) is higher than that of structural adhesive.
  & nbsp; & nbsp; 2. Silicone structural adhesive not only has the characteristics of weather resistant sealant, but also has stronger bonding function than weather resistant sealant, mainly manifested in strong tear resistance, cracking elongation, and tensile strength. Tensile strength is mainly used in pre stressed areas. The modulus, hardness, strength, and price of structural adhesive are higher than those of weather resistant adhesives of the same level.
  & nbsp; & nbsp; Summary: The weather resistance of structural adhesive is as good as or even better than that of weather resistant adhesive. As the weather resistance of structural adhesive is related to safety, if it ages quickly, the glass will fall off severely. Therefore, the current structural adhesive is basically silicone (silicone adhesive), which will not age in the natural environment. Weathering glue does not affect safety, and the main effect of failure is usually water and air leakage. Therefore, there are many types of materials for weathering glue, including polyurethane, polysulfide, acrylic acid, etc., but silicone is still the best for weather resistance.
