Two-component polysulfide sealant for expansion joints in Guangdong Foshan Water Plant and Wastewater Treatment Plant, self-leveling and non-sagging type
Common name: polysulfide sealant, building sealant, two-component polysulfide sealant (paste ), elastic rubber sealant
Product Introduction
Polysulfide building sealant is a two-component sealant (component group) that is formulated with liquid polysulfide rubber as the base material and can self-vulcanize and cross-link at room temperature. (min.~.), it has good adhesion to metals, concrete and other materials, can be continuously expanded and contracted, maintains good air tightness and waterproofness under vibration and temperature changes, and is oil and solvent resistant, with excellent durability.
It is suitable for anti-seepage sealing of metal and concrete curtain wall joints, underground projects (such as tunnels, culverts), reservoirs, reservoirs and other structures, as well as expansion and contraction sealing of expansion joints such as highways and airport runways, buildings Repair of cracks restores seal.
Product classification
According to the fluidity, it can be divided into two types: non-sag type and self-leveling type
According to the shifting ability, it can be divided into two levels
According to the pulling ability The elongation modulus can be divided into high modulus and low modulus
Construction Guide
. Use a wire brush and a dust knife to clean the debris and floating dust in the grooves.
.Deeper joints should be filled with foam plastic as the backing material, or other plastics or wood can be used as the backing to reduce the waste of sealant. The thickness of the glue injected is .times of the seam width. For example, when the seam width is Use a special glue gun to inject glue. When injecting glue, the nozzle should move evenly and slowly to ensure that the joints are fully filled and to prevent air bubbles from being left behind.
