AI-Powered supplier vetting

SummarySWD NEW MATERIAL (SHANGHAI) CO., LTD. is a China-based limited trading company established in 2006, focused on polyurea, polyurethane, anticorrosion, waterproofing, and related construction chemicals. The available information indicates a Shanghai commercial entity with manufacturing operations in Nantong, Jiangsu, five production lines, ISO 9001:2015 certification, documented R&D personnel, and export activity since 2013. Its stated capabilities include spray polyurea production, multiple coating product series, self-operated import and export rights, and several accepted trade and payment methods. However, the evidence does not establish after-sales service systems, customer references or cases, customization arrangements, or detailed financial reliability. Some operational figures are inconsistent across the supplied records, particularly facility size and production-related descriptions, so those points should be independently verified.

Supplier typeThe supplier is explicitly identified as a trading company and limited company based in Shanghai, China, engaged in construction and decoration chemicals. Its stated business focuses on R&D, production, and sales of polyurea and polyurethane anticorrosion coatings, indicating a trading entity with associated manufacturing activities.

CertificationsThe supplier holds an ISO 9001:2015 certificate according to the supplied information. This provides explicit evidence of a certified quality-management system, although the certificate scope, issuing body, and validity period are not provided.

R&D capabilityThe supplier states that it drives product innovation and conducts R&D in polyurea and polyurethane anticorrosion coatings. The records also identify five R&D engineers and several specialized product series, supporting an active product-development capability, although no patents, research outputs, or innovation performance metrics are provided.

Production capacityThe supplier reports five production lines, production operations in Nantong, a spray-polyurea annual productivity figure, and multiple product series covering spray and hand-applied polyurea, polyurethane, waterproofing, and anticorrosion coatings. This supports diversified manufacturing capability, but the supplied records contain inconsistent facility and production descriptions that require verification.

Product Q&A

Q:How should the substrate be prepared before application?

Metal surfaces should be sandblasted to Sa2.5 level. Concrete must be strong, dense, flat, clean, and dry. Wood must be clean, dry, and free of burrs or loose debris.

Q:What are the recommended application methods?

The coating can be applied by airless spraying, air spraying, brushing, or rolling. It is a single-component product requiring no mixing.

Q:Is the coating suitable for outdoor use?

Yes, it has excellent UV resistance and anti-aging properties. It will not powder or change color after 1000 hours of accelerated aging.

Q:What is the theoretical coverage of the coating?

The theoretical coverage is 0.16kg/m2 at a thickness of 100um. Recommended dry film thickness is 100-200um.

Q:What is the curing time for the coating?

Surface dry time is 3-6 hours depending on temperature. Foot traffic is allowed after 20-30 hours, and full solid curing takes 5-7 days.
