Single component polyurethane water-swelling sealant is a kind of polyurethane type amorphous paste with one-component, solvent-free, water swelling. The amorphous paste ensure that it can be used to prevent infiltration in irregular base. It has double sealed water stop function. Single component polyurethane water-swelling sealant not only has elasticity water stop of rubber but also has volume expansion stop water after soaking. And it can be cured in humid environments. Curing time depends on the temperature and humidity of environments. Compared with waterstop, it can be used in various irregular seams, especially between different materials, wet, pile head and other parts. And it also can be used in vertical surface without sag. Water-swelling sealant can be divided into two kinds according to the swelling ratio: PJ220 and PJ400. It is the economic choice for customers.

Single component polyurethane sealant, as known as a single component, hydrophilic, water activated, hydro active, expandable, gungrade waterstop, is also called single component polyurethane hydrophilic expansion waterproofing sealant. When in contact with water, the sealant expands and produces an expanding pressure. The pressure between the expanded sealant and the surrounding concrete structure prevents water penetration through the joint and provides a durable waterproofing solution. Advantages Based on the physical and chemical properties of the polyurethane sealant, it has many advantages. Such as: Expansion rate. The polyurethane sealant has a strong expansion capacity. It can expand to 220% or 300%, 400%, 500%, even 600% of its own volume. Strong adhesion. It can used to steel, HDPE, PVC, and other common building materials, and it also effective to damp surfaces. Good weather resistance. It has low temperature flexibility, and its service life of up to 15 to 20 years. Environmentally non-toxic. It has good chemical resistance, and it tested can be resistant to hydrochloric acid, salt water, sodium carbonate, potassium hydroxide and other chemicals. In addition, it is safe and non-toxic when in contact with drinking water, belongs to environmentally friendly products. Ease to use. It can be applied with a standard caulking gun. Application Polyurethane sealant is widely used in construction, transportation and other industries. Such as the following usage: Caulking agent. The polyurethane sealant is used as caulking agent in the construction of subways, tunnels, underground parkings and other projects. Sealing waterproof. In building construction, it can play a role of sealing waterproof for doors and windows, exterior walls and other parts. Water stop. It can be used as water stop when punctures are found in plumbing, sewer lines and other utility pipes.

Product Name: CROSCARMELLOSE SODIUM Appearance: White Powder Soluble: Good solubility in water CAS No: 74811-65-7 EINECS No: 1312995-182-4 Supplier: ZHENYIBIO Croscarmellose sodium is used in oral pharmaceutical formulations as a disintegrant for capsules,tablets, and granules. In tablet formulations, croscarmellose sodium may be used in bothdirect-compressionandwet-granulationprocesses.Whenused in wet granulations, the croscarmellose sodium should be added in both the wet and dry stages of the process (intra- and extragranularly) so that the wicking and swelling ability of the disintegrant is best utilized. Croscarmellose sodium at concentrations up to 5% w/w may be used as a tablet disintegrant, although normally 2% w/w is used in tablets prepared by direct compression and 3% w/w in tablets prepared by a wet-granulation process.

Dimethyl Formamide Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics. Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc. Packing: 190kg Drum, IBC, ISO Tank, Flexi Bag.
