What is silicone adhesive?
Silica gel is an ointment. Once it comes into contact with moisture in the air, it will solidify into a tough rubber-like solid substance. Mainly divided into deacetylation type, dealcoholization type, deamination type and depropylation type. Silicone adhesive is commonly known as glass adhesive because it is often used to bond and seal glass.
Silicone glass glue has strong adhesion and tensile strength, and has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and adaptability to cold and hot changes. In addition, its wide applicability can realize the bonding between most building materials products, so its application value is very great.
Silicone adhesive uses:
Silicone glass glue will not flow due to its own weight, so it can be used for seams on the top or side walls without sinking, falling off or flowing away. Mainly used for bonding clean metal, glass, most oil-free wood, silicone, vulcanized silicone rubber, ceramics, natural and synthetic fibers and many painted plastic surfaces. Good quality silica gel glass glue will not be squeezed when used below zero degrees Celsius, and its physical properties will not change. The fully cured silicone glass glue can still be used at 204℃(400oF), but the effective time will be shortened when the temperature is as high as 2 18℃(428oF).
Use acidic glass glue
1, suitable for sealing, plugging, leak-proof and weatherproof purposes, both indoors and outdoors (the indoor effect is better), and the seepage-proof and leak-proof effect is remarkable. 2. Bonding various automobile interiors, including metal, fabric, organic fabric and plastic. 3. Connect the gasket on the heating and cooling equipment. 4. Add ribs without screw holes, nameplates and painted plastic materials on the metal surface. 5. Seal the windows on the oven door, the flue, pipe joint and access door on the gas appliance. 6. Provide instant molded leak-proof pads for gear boxes, compressors and pumps. 7. Seal the cabin and windows. 8, trailer, truck cab glass window sealing. 9. Bonding and sealing equipment parts. 10, forming a wear-resistant coating. 1 1. Embedding and filling of thin metal laminates, pipe networks and equipment shells.
Use neutral weather-resistant adhesive
1, suitable for weatherproof sealing of various curtain walls, especially recommended for weatherproof sealing of glass curtain walls, aluminum-plastic curtain walls and stone dry hanging; 2. Joint sealing between metal, glass, aluminum, ceramic tile, plexiglass and coated glass; 3. Joint sealing of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. Primer is not needed in most cases.
Use of silicone structural adhesive
1, mainly used for structural or non-structural bonding assembly between glass curtain wall metal and glass. 2. It can directly connect the glass with the surface of the metal component to form a single assembly component, which meets the design requirements of the fully hidden frame or semi-hidden frame curtain wall. 3. Structural bonding and sealing of insulating glass.
Silicone adhesive standard:
Identification method of silicone adhesive:
There are many kinds of silicone adhesives:? Silicone sealants, polyurethane sealant, polysulfide sealant, acrylic sealant, anaerobic sealant, epoxy sealant, butyl sealant, neoprene sealant, PVC sealant and asphalt sealant. ? Identification of silicone adhesive mainly depends on the following properties: 1. Breaking strength (breaking force/cross-sectional area)? ; Second, bonding strength (pull-off force/bonding area, except substrate damage); ? 3. Elongation at break (broken length/original length)? ; Fourth, anti-aging ability? ; 5. Appearance (matt, particles, bubbles); ? Six, shape retention (no wire drawing, no sagging facade); Seven, shelf life? ; Eight, curing time? .
There is no difference between good and bad, and performance corresponds to price, which is the best. Secondly, there is stability and adequacy, which is a test for manufacturers. ? If the capacity of sealant is less than the marked capacity (Note: capacity. This situation of sealant is very serious), so this kind of sealant should be ruled out first, so there is something wrong with the business ideas of such enterprises and the products are not much better. There are many problems, which prove that the production process of its products is not strictly controlled. If the dosage is large, the production stability of sealant should be considered.
