Premium Polyurethane Sealant for Construction & Industrial Use
Polyurethane sealant （abbreviation PU sealant）is a high-performance sealing material with polyurethane rubber and polyurethane prepolymer as the main components. It is famous for its excellent elasticity and can quickly return to its original shape after being subjected to pressure, ensuring a long-lasting and stable sealing effect.
The polyurethane sealant produced by Tanyo Industrial is made of high-quality raw materials and manufactured through precision technology. The colloid is fine and has no impurities and no irritating smell. It not only has excellent elasticity but also many advantages, such as oil stain resistance, low-temperature resistance, and wear resistance. It can maintain stable performance in various complex environments. Whether in industrial production or daily life, Tanyo polyurethane sealant is your best choice.
Polyurethane Sealant By Feature
With a full range of technologies, including hot-melt and room-temperature vulcanization, we provide one-component and two-component polyurethane based sealant solutions for global clients.
We offer moisture-curing formulations specialized for wood and glass, as well as chemical-curing solutions for high-strength concrete expansion joints.
Whether it’s the sag resistance required for vertical construction or the long-term waterproof reliability for roofing metal, we ensure precise bonding and sealing for every substrate.
If you need assistance with product selection, please contact our technical team. We will provide customized product matching based on your performance requirements.
-
One Component Polyurethane sealantTanyo single-component polyurethane sealant uses moisture cure technology to develop high elasticity and toughness at room temperature. Its waterproof and weather-resistant properties provide a reliable seal across metal, plastic, glass, and wood. A streamlined, effective solution for heavy-duty bonding.
-
Two Part Polyurethane SealantThis two-component polyurethane sealant uses a chemical cure mechanism to achieve fast, uniform curing regardless of joint depth or humidity. Its high tensile strength and elastomeric recovery make it a reliable choice for expansion joints in concrete and large-scale construction. A high-build, durable solution for heavy-duty sealing.
Polyurethane Sealant By Color
We offer flexible polyurethane sealants in a variety of regular colors, including clear, black, white, gray, brown, and red. These colors are capable of meeting most industrial and commercial needs.
At the same time, we can provide customized color services according to the specific needs of customers. All colorants used have been strictly tested to ensure that they do not contain harmful substances and irritating odors, comply with international environmental protection and safety norms, and ensure the health and environmental protection of construction workers.

Tanyo polyurethane sealant is engineered for high-strength sealing across cement concrete roof cracks, gutters, and masonry walls. Beyond typical windows, balconies, and car windshields, it provides a durable, weatherproof bond for wood decks and substrates including ceramic, PVC, plastic, and metal.
Polyurethane sealant is in the form of a paste and forms a rubber-like elastomer after curing, which has good adhesion and sealing properties.
Polyurethane foam sealant has a foam-like structure after curing, with low density, but good filling and thermal insulation properties.
Certainly, tanyo polyurethane sealant can be painted on decorative surfaces without causing any rejection with the paint.
Polyurethane sealant typically requires 1-3 hours to become surface-dry and approximately 1-3 days to fully cure. Curing time significantly extends in winter, with the specific duration depending on ambient temperature and humidity.
Polyurethane sealant is toxic in its uncured state and emits harmful fumes during the curing process. Therefore, gloves and masks must be worn during application to avoid health hazards. Once fully cured, it forms a stable, non-toxic solid material.
Under normal conditions, the service life of polyurethane sealant can exceed 10 years; however, in harsh environments such as high temperature and high humidity, its aging rate will significantly accelerate.
Our standard packaging of sealants is 300ml cartridge and 600ml sausage, 40 pcs in a carton.
Of course, we support customized packaging, color, and other specification services.
Yes, we support small trial orders and wait until you are satisfied with our products before ordering in large quantities.
