Supply of two-component polyurethane sealant

Two-component polyurethane sealant component polyurethane sealant for use in civil construction, transportation, precast concrete and other building materials and construction joints connecting fill seal. High roads, bridges, runways, underground pipelines, joint sealing joints and expansion joints and Deformation tunnels and buildings. Features: two-component polyurethane sealant with excellent wear resistance, low temperature flexibility, performance can adjust a wide range, high mechanical strength, good adhesion, elasticity, excellent resilience, may be suitable for dynamic joints and deformation joints, expansion joints. Good weather resistance, oil resistance, resistance to biological aging and low prices. Product Construction Methods: Primary treatment: The sticky surface must be neat processing (available portable cutting machine, wheel, steel brush, etc.), so that the exposed adhesive surface layer of solid structure. Joint surface must be completely dry, clean and free of frost. The surface of all dust and cement slurry must clear brush handle clean. Rust and paint protection also need to remove the metal surface. If the structure quit, available blowtorch drying. A front surface coating must first primer coating liquid. Just brush a thin layer of liquid primer, wait until the sticky surface before coating caulking sealant. (The company is supported by a variety of bottom paint supply) Description Note: First, the building must be kept dry, clean and free of grease. Second, the construction should be preceded by the primer was applied to the surface, until the surface is dry on both sides of the gap of 10mm to 50mm wide at affix protective tape to prevent the construction of excess polyurethane sealant to the surface structure dirty. Third, The barrel inside white polyurethane sealant (A component) and one bag of black hardener (component B), stir until no color so far. A: B = 100: 8-12, should be preceded by a small test. Fourth, the mixing well with a gray polyurethane sealant squeeze glue gun or knife compacted fill to fill in the joints, then ≥10cm wide putty knife gum gelling. Five flat glue applied after the protective tape can be removed within 24 hours to avoid water will rain. (Dry time ≤24 hours, seven days before the irrigation experiment, 28 days to reach full performance.) Six, formulated polyurethane sealant to be used up within two hours, otherwise it will slowly solidified paste difficulties caused by the construction, avoid waste. Note: This product is divided into N-type, L-type two kinds.
