What are the main features of KASTAR 4000?

It is a silicone elastic waterproof coating that is non-corrosive, has high elongation, and offers strong waterproofing. It features weather, corrosion, UV, acid/alkali, and oil/water resistance, along with electrical insulation and high adhesion.

What is the Self-Leveling Effect?

It describes the coating flowing smoothly across a surface and settling into a flat, horizontal plane under gravity alone. It minimizes surface tension and unevenness, ensuring a smooth finish without manual troweling.

What is the Lotus Effect?

Inspired by lotus leaves, this effect creates a superhydrophobic surface where water droplets form spheres and roll off effortlessly, picking up dirt and dust for self-cleaning without chemicals or wiping.

AI-Powered supplier vetting

SummaryThe supplier manufactures and sells silicone rubber products, plastic products, and sealant fillers, with import and export capability. It reports 20 production lines, in-stock capacity, lead times within 15 workdays in both peak and off-season periods, and access to nearby Foshan, Guangzhou, and Shenzhen ports. The supplier states that it has more than 300 OEM customers and holds ISO9001, CE, and SGS certifications; however, the structured data separately indicates no OEM service for popular brands. Its R&D supports several forms of customization and reports new products in the past year, but it does not provide ODM, 3D design, or SDK services. Limitations include no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, agents, branches, showroom, or offline trade-show participation, and no regular fire drills in the past year. Financial evidence is insufficient for a substantive credibility assessment.

Supplier typeThe supplier is identified as a combined company engaged in production, manufacturing, sales, and import/export of silicone rubber products, plastic products, and sealant fillers. It is not described as an offshore company and reports no overseas agents or branches, indicating a primarily direct, factory-based supplier structure.

CertificationsThe company description states that the factory has passed ISO9001, CE, and SGS certification, while the structured data specifically identifies an ISO9001:2015 certificate. These are explicit certification claims, although the slices do not provide certificate validity dates or scope details.

Production capacityThe supplier reports 20 production lines, in-stock capacity, more than 300 OEM customers, and lead times within 15 workdays year-round. Countervailing weaknesses are the absence of a valid manufacturing-capacity contract with related subcontractors, no ongoing batch quantity reconciliation, and no standard operating procedure for outsourced manufacturing.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It does not provide 3D software design or ODM services, so the evidence supports product customization but not comprehensive design-led development.
