Product Introduction:
Solvent-based adhesives are a new type of bridge deck waterproofing material. They are a one-component solvent-based waterproofing adhesive formed by dissolving asphalt, various high molecular weight resins, and additives in a specific solvent through special processing. The main characteristics of solvent-based adhesives, in addition to their excellent waterproofing properties, are their effectiveness in dealing with interlayer bonding issues between concrete (steel plate) and asphalt concrete. Under the action of external load levels (especially in higher temperatures), the pavement is less prone to problems such as shifting, peeling off, and deformation. Suitable for interlayer waterproofing and bonding of cement concrete bridge decks, steel bridge decks, tunnel road surfaces, or other composite pavement installations, especially where the pavement has slopes (transverse and longitudinal) and the bridge deck overlay layers are thin.At7mm waterproof and adhesive properties.
Product Features
◆ Excellent waterproof performance. Low viscosity, strong penetration; effectively penetrates cement concrete or steel plates to form a dense waterproof layer, effectively protecting the bridge structure.
High bonding strength of the interface. The coating has high strength, with strong adhesion to cement concrete or steel plates, as well as high bonding strength at the interface.
The shear and bonding performance of the composite structure after paving asphalt concrete, compared to traditional waterproofing materials (such as waterproof membranes, water-soluble waterproof coatings, reactive waterproof materials, etc.), the bonding strength is significantly improved, and the composite structure's shear and bonding performance after paving asphalt concrete is excellent.
◆ The coating has excellent flexibility, offering strong adaptability to the shrinkage and cracking of the base layer.
Easy to install, with application at room temperature and single-component mixture.
◆ wuduEco-friendly, pollution-free.
Application Scope
Waterproofing and bonding for concrete bridge decks, tunnel surfaces, and other composite road surfaces.
Base Treatment: For steel bridge decks, sandblasting rust removal must be performed prior to construction, ensuring cleanliness.Sa2.5 grade, surface roughness up to 50~100µm; for cement concrete substrates, they should be firm, clean, and dry, with no loose coatings or oil stains on the base surface. For areas with oil stains, solvent cleaning is mandatory. For substrates with laitance, laitance must be removed.
Product Application: This product is a single-component, low-viscosity liquid. During application, pour it into a container of appropriate size and gently stir.3 to 5 minutes, the construction method can be divided into two types: two coatings, solvent-based adhesive spray usage is 0.4 to 0.7 kg/㎡. If the base surface is uneven, you can choose a larger coating amount: ① Manual application
Fabric: ProcessedThe roller is used to evenly apply it on concrete or steel plates after shot blasting rust removal. ② Machine Coating: Provided byOperationPerson holding a spray gunFirearmPlease provide the Chinese content to be translated.FirearmThe rear bend pipe directly吸取solvated adhesive from the raw material drum, spraysFirearmA solvent-based adhesive is sprayed out in a mist form, covering the bridge evenly.diOne-coat applicationIn one hour, proceed.diTwo-coat spraying. After the solvent-based adhesive film is completely dried, paving of the asphalt mixture can be carried out. The curing time of the solvent-based adhesive film mainly varies with the temperature, with the approximate correlation as shown.
Note: Please be aware that if testing the adhesive strength of solvent-based adhesives with steel plates or concrete,The pull head must be attached to the solvent-based adhesive film surface only after the adhesive has fully cured.
