Two-component polyurethane sealant polysulfide sealant polyurethane sealant King County Extension of Rubber Products Co., Ltd. specializes in producing a two-component polyurethane sealant polysulfide sealant polyurethane sealant Specifications: 25kg / part number 1366 3286655, with a very good wear resistance, low temperature flexibility, performance, adjustable wide range, high mechanical strength, good adhesion, elasticity, excellent resilience. Two-component polyurethane sealant for use in civil construction, transportation, precast concrete and other building materials and construction joints connecting fill seal. Senior roads, bridges, runways, underground piping, joint sealing joints and expansion joints and Deformation tunnels and buildings. Features: Two-component polyurethane sealant polysulfide sealant polyurethane sealant with excellent wear resistance, low temperature flexibility, performance can be adjusted a wide range, high mechanical strength, good adhesion, good elasticity, excellent recovery sex, may be suitable for dynamic joints and Deformation, 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 deal (available portable cutting machine, wheel, steel brush, etc.), so that the exposed adhesive surface layer of solid structure. You must ensure that the joint surface dry, clean, no cream. Surfaces of all dust and cement slurry must clear brush handle clean. Rust and paint protection also need to remove the metal surface. Structures such as quit, can blowtorch drying. Front surface coating must first primer coating liquid. Just brush a thin layer of primer liquid was allowed to sticky surface before coating caulking sealant. (The company is supported by a variety of bottom paint supply) two-component polyurethane sealant polysulfide sealant polyurethane sealant for use 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 and attach protective tape to prevent the construction of excess polyurethane sealant to the surface structures dirty. Third, The inside a bucket of white polyurethane sealant (A component) with a black bag curing agent (component B), stir until no color so far. A: B = 100: 8-12, 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 glue gelling. Fifth, after applying the protective tape flat plastic can be removed within 24 hours to avoid water will rain. (≤24 hours dry time, seven days before the irrigation experiment, 28 days to reach full performance.) Six, two-component polyurethane sealant formulated polysulfide sealant polyurethane sealant should be used within two hours, otherwise it will cream slowly due to construction difficulties caused by curing, to avoid wastage. Note: This product is divided into N-type, L type two. PS-851 two-component polyurethane sealant Technical Specifications Standard JC / T482-2003
