Based in Junan County, Linyi City, Shandong Province, China, SAIQIANG GLOBAL stands as a titan in the adhesive industry. As a leading manufacturer in Asia, we specialize in high-performance bonding solutions, including clear urethane caulk, silicone sealants, and PU foams. Our daily production capacity of 200,000 units allows us to serve 62 countries with unmatched efficiency.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is reflected in our rigorous adherence to international standards and environmental sustainability.
Clear urethane caulk requires precise chemical balancing to achieve crystal-clear transparency while maintaining UV stability. Our laboratory, based in Shanghai Sijing Industrial Park, focuses on low-VOC, high-elasticity formulas that outperform traditional silicones in paintability and durability.
With 26 automated filling production lines and a production base exceeding 100 acres, we mitigate supply chain risks. Our annual output of over 50,000 tons ensures that global distributors receive their orders without the lead-time bottlenecks common in smaller factories.
We hold ISO 9001:2015, China's Ten-Ring Certification, and France's A+ Indoor Air Safety Certification. Our products meet CE, ROHS, and REACH requirements, ensuring seamless entry into European and North American markets.
In the world of professional sealing, "Clear" doesn't always mean "Invisible." Traditional clear silicones often develop a yellowish tint over time due to UV exposure and cannot be painted over. Clear Urethane Caulk represents a significant "Information Gain" for engineers and architects.
Superior Paintability: Unlike silicone, urethane caulk accepts most architectural coatings, allowing for a seamless aesthetic finish. This makes it the preferred choice for high-end residential molding and commercial facades.
Dynamic Joint Movement: Urethane sealants possess higher tear strength and abrasion resistance. In areas with high foot traffic or structural vibration, urethane maintains its bond where silicone might delaminate.
Substrate Versatility: China-manufactured clear urethane from Saiqiang is engineered to bond with porous and non-porous surfaces alike—glass, wood, concrete, and metals—without the need for a primer in most applications.
Submerged Durability: Certain polyurethane formulations are capable of handling intermittent water immersion, a feat many standard caulks cannot claim. This increases the safety margin for exterior window sills and threshold applications.
In modern architecture, clear sealants are vital for curtain walls. Our products provide the invisible bond required for glass-to-glass joints, ensuring thermal efficiency without compromising the "all-glass" visual intent.
Clear urethanes are increasingly used in the assembly of EV battery packs and vehicle windshields, where vibration damping and weatherproofing are critical requirements for safety and longevity.
As the world moves toward Prefabricated Prefinished Volumetric Construction, our fast-drying urethane formulas allow for rapid assembly and transport of modules without joint failure during transit.
The push for Net Zero buildings is driving demand for bio-based polyurethane sealants. Saiqiang is currently researching plant-derived polyols to reduce the carbon footprint of our caulk line.
Next-gen clear caulks are being engineered with advanced UV absorbers that prevent the typical "fogging" or "yellowing" effect, maintaining 99% clarity over a 20-year lifecycle.
Global procurement needs are shifting toward "sustained freshness" packaging—cartridges with improved oxygen barriers to extend shelf life during long-distance maritime shipping.

Since 2005, Shanghai Saiqiang Chemical Co., Ltd. has been committed to silicone rubber and foam rubber research. Our factory in Sijing Industrial Park covers 100+ acres and maintains a brand quality route, pursuing excellence. We provide personalized services and support, striving to exceed customer expectations.
For bulk buyers and distributors, selecting a China Clear Urethane Caulk factory involves more than just price. It requires a partner who understands international logistics and material compatibility.
We offer free material compatibility testing for global partners. Before you order 10,000 units, our lab tests the caulk against your specific aluminum or composite substrate to guarantee zero delamination.
We don't just sell product; we provide knowledge. Saiqiang offers technical training for our distributors' sales teams, ensuring they can explain the "Polyurethane vs Silicone" difference to end-users.
For OEM/ODM partners, our Shanghai lab is your lab. We can customize shore hardness, cure speed, and viscosity to meet specific regional environmental conditions.
Q1: Can clear urethane caulk be used for exterior window sealing in high-UV regions?
A: Yes. Saiqiang's clear urethane is formulated with advanced light stabilizers. Unlike standard urethanes which might yellow, our "Clear" series is designed to withstand intense UV exposure without losing clarity or elasticity.
Q2: What is the shelf life for bulk shipments from China?
A: Our standard shelf life is 12 months. For global partners, we use vacuum-sealed aluminum cartridges and nitrogen-purged filling to ensure the product remains stable during the 30-45 day sea transit period.
Q3: Is it paintable immediately after application?
A: While urethane is paintable, we recommend waiting for the "tack-free" state (usually 2-4 hours depending on humidity) before applying water-based paints. For oil-based paints, a full cure (24 hours) is recommended for best results.
Q4: How does Saiqiang ensure consistent quality across 200,000 units per day?
A: We utilize an ISO 9001:2015 certified real-time monitoring system. Every batch undergoes viscosity, tensile strength, and clarity testing. Each cartridge is stamped with a batch number for full traceability.
