product introduction
Two-component polysulfide sealant, liquid polysulfide rubber as the main agent, adding reinforcing agent, toughening agent, viscosifier, thixotropic agent and other additives configuration processing into the base paste; The metal oxide is configured as a vulcanization paste, and the two components can be cured as an elastic sealing material after mixing. The two-component polysulfide sealant is a class B grade grade polysulfide sealant, which is vulcanized at room temperature with liquid polysulfide rubber as the base material and has the ability of caulking and sealing water. The other is a two-component polysulfide sealant. Component A is bottled white paste, component B is bottled liquid curing agent, (in order to facilitate the construction party's pigment requirements, the color is packed in a separate box, one in one group). When used, all the B component liquid is squeezed into the A component bucket, and the pigment is added according to the construction color requirements, and the mixture is quickly mixed up and down until uniform. Use a small spatula to spread the mixed sealant into the area to be constructed. After 48 hours can be immersed and water contact.product characteristics
1, with good weather resistance, durability, long-term use does not produce cracking;
2, it has sufficient stable adhesion and durable adhesion to the sealed component, and long-term adhesion to the concrete in water;
3, the water vapor transmission rate is very low, the two-component polysulfide sealing paste has a very good waterproof function;
4, not corroded by fungi, excellent resistance to fungi;
5, the construction is good, the two-component polysulfide sealant can be well filled into the joint;
6, with excellent resistance to fuel oil, hydraulic oil, water and various chemicals;
7, the sealing component does not produce pollution, no corrosion, two-component polysulfide sealing paste is harmless to the human body.Main uses
1, Waterproof sealing of metal, concrete curtain wall joints, underground works (such as tunnels, caves and culverts), reservoirs, reservoirs and other structures
2, Repair and restore sealing of cracks in buildings;
3, other multiple uses.Instructions for use
1, The treatment of the sealed surface should remove the oil, attachments, dust and other debris on the glued surface before construction to ensure that the glued surface is dry and smooth to prevent poor bonding.
2, fill the backing material, according to the design requirements, fill the backing material to the seam.
3, the preparation of sealant, according to the mix ratio given in the instructions, the two components are mixed evenly, can be used, regardless of machine mixing or manual mixing, should achieve uniform color without color difference. When mixing, bubbles should be prevented from mixing, and when applying glue, bubbles should be prevented from mixing, compacting, and filling the seal.Packaging
Two-component polysulfide sealant is available in 25kg boxes or 25kg drums.Restrictions on use
The B component paste should be fully invested in the A component, otherwise it will affect the curing time and colloidality. The sealant should be used up as soon as possible after uniform preparation (application period of 2 hours) to avoid waste caused by paste curing (can not be constructed after curing). The installation of the construction interface should be clean and dry, otherwise it will affect the bonding force of the sealant. Avoid water flushing and rain within 48 hours after completion of construction.Safety Instructions
This product is not toxic after full curing, but before curing should avoid contact with eyes, if contact with eye knot, please rinse with plenty of water, and seek medical treatment; The uncured product should be kept away from children, and the product should pay attention to ventilation during the curing process.
