>Overview Edit
> This sealant is a solvent-free one-component room temperature curing sealant. The sealant is in the form of a paste and can be applied by extrusion or smearing. It is anti-sag, and the vertical seams and top seams are filled without bleeding. The cured glue layer is rubbery and elastic. It has adhesion to metal, rubber, wood, cement components, ceramics, glass, etc. Sealant is a material used to fill gaps (holes, joints, seams, etc.) and has both bonding and sealing functions.
>Application Industry Editor
>Polyurethane sealants are widely used in civil construction, transportation and other industries
>. In construction applications, filling and sealing of doors, windows, glass, etc.
>. In civil engineering applications, caulking sealing of highways, bridges, airport runways, etc.
>. In automotive applications, assembly sealing of windows (mainly windshields).
>Sealant is a material used to fill gaps (holes, joints, seams, etc.) and has both bonding and sealing functions. Polyurethane sealant, silicone sealant, and polysulfide sealant constitute the three major varieties of high-end sealants at present.
>Characteristic editing
>.Wide adjustable range of performance and strong adaptability
>.Good wear resistance
>.High mechanical strength
>.Adhesive performance Good
>. Good elasticity, excellent recovery, can be used for dynamic seams
>. Good low-temperature flexibility
>. Good weather resistance, service life up to ~ years
>. Good oil resistance
>. Resistant to biological aging
>. Moderate price.
> Advantages: One-component is mainly compared to two-component. There is a two-component polyurethane glue. When using it, component B and component B need to be mixed evenly in proportion to achieve bonding and sealing. The single-component product can be used directly, which is convenient, concise and easy to construct. Moisture curing means that the one-component polyurethane glue is cured by reacting with trace amounts of water vapor in the air, and reacts with the active groups on the surface of the substrate to play a bonding role.
> Compared with traditional silicone glue, polyurethane glue has more than times the high elongation and more than times the bonding strength.
>Single-component polyurethane glue is non-toxic after complete curing and can be used in drinking water projects. It has been authoritatively tested

> The water-swellable water-stop sealant provided by our company is a single-component, moisture-cured, solvent-free, water-swellable polyurethane waterproof sealant. It has the elastic water-stop of rubber and its own volume expansion after swelling with water. The dual waterproofing mechanism of waterstop has good construction operability and base surface adhesion. It is an upgraded product of traditional waterstop strips and a leading solution for waterproofing of building joints
