Many of my friends inquire about the two-component polysulfide sealant after sizing. Is it possible to directly apply water for irrigation? Today Xiaohong's Xiaobian talks about the test time of the two-component polysulfide sealant sizing. The two-component polysulfide sealant is a room-temperature-curing sealant composed of A and B components. The polysulfide sealant has a sizing time of 2 hours, a tack free time of 24 hours, and a 2×3 cm slit substantially completely cured after 7 days. That is, after 7 days, the water can be tested, and the performance of the 28-day double-component polysulfide sealant can be achieved. Two-component polysulfide sealant, also known as polysulfide waterproof sealant, polysulfide construction sealant, two-component polysulfide sealant, polysulfide compound sealant, PS construction sealant, elastic rubber sealant. 
The two-component polysulfide sealant produced by our factory is mainly used for sealing joints such as expansion joints in the construction, municipal, subway, tunnels, airport runways, highways, and bridges, settlement joints such as settlement joints, and two-component polycondensation. Sulfur sealant is suitable for sealing joints of various expansion joints in waterworks, swimming pools, reservoirs, power stations, dams, sewage treatment works, and water supply and drainage systems.
The two-component polysulfide sealant is a two-component paste. There are obvious color differences between the two components. The A component is a white material and the B component is a black material. The use ratio is A:B=100:8-12, and the sizing time is 2-6 hours. Two-component polysulfide sealant is neutral, non-toxic, environmental protection, pollution-free, anti-corrosion, anti-bacterial, water and oil resistant, weak acid and alkali resistance, good anti-aging properties, long service life, with good anti-leakage adhesive seal effect.
My company specializes in the production of two-component polysulfide sealant is divided into two types: one is non-sagging two-component polysulfide sealant; one is a self-leveling two-component polysulfide sealant.
