Guangzhou, October 2026 — Enjoycool Technology has confirmed its standing as a National High-Tech Enterprise and as a member of the World Waterpark Association (WWA), alongside continued certification under ISO quality, environmental and occupational health and safety management systems.
The qualifications support the company's position as a supplier to public-sector water park projects and to international developers who require documented management-system certification as a condition of tender.
Why these particular qualifications matter
For a specifier or procurement team, qualifications are not a marketing list. Each one answers a specific question that appears in a tender document.
National High-Tech Enterprise status requires a documented research and development programme, a minimum proportion of technical staff, and registered intellectual property connected to the company's core products. For a buyer, it is evidence that the formulation work behind a coating is ongoing rather than bought in — which matters when a project requires product adjustments for a specific substrate or climate.
WWA membership connects the company to the international water park industry's safety and operations community. For water park operators, working with a supplier that participates in that community means the material specifications reflect the operational realities of a facility that runs daily with chlorine, high footfall and a fixed maintenance calendar.
ISO management systems — quality, environmental and occupational health and safety — provide the audit trail that public procurement and large developers require: documented procedures, traceable batch records and a formal non-conformity process.
Patent position
The company holds a granted national invention patent covering the Epoxy-Urea-Bond underwater protective and decorative coating (patent number ZL202210369265.3). The formulation combines imported weather-resistant epoxy resin with polyaspartic polyurea, which addresses the practical limitations of conventional polyurea coatings: demanding application conditions, poor substrate adhesion and complex multi-step processes.
The SLETU elastic brick system has been filed as a domestic-first application with multiple invention and utility-model patents secured or pending. Together these cover the chemistry of the underwater coating and the mechanical system used to bond decorative surfacing to substrates that move.
Testing and certification scope
Product data is reported against the test methods that European and North American projects specify, including ASTM D3359 for adhesion, ASTM B117 for salt spray, ASTM G155 for xenon-arc weathering, ASTM E903 and C1371 for solar reflectance and infrared emittance, EN 13501-1 for reaction to fire, and DIN 51130 for slip resistance in wet barefoot areas.
Safety data sheets follow the ISO 11014 / GHS structure, and formulations are documented against EU REACH, RoHS 2.0 and the EU VOC Directive.
What the company does with the qualification
Qualification status is only useful if it changes how projects are delivered. For Enjoycool, it produces three practices that a project team will see in the documentation pack:
- Batch-level test data supplied with delivery, not only a generic product certificate
- Site-specific system build-up drawings that name each primer, mortar and topcoat in sequence
- Documented hold points for substrate moisture, adhesion testing and detail inspection before the next layer is applied
