Fast Drying Without Surface Defects: What the Product Data Says

The available product information does not identify a water-based polyurethane (PU) grade specifically designed for fast drying without surface defects. For wood sealing, it instead specifies EP-8801 with OS-8802, a solvent-free, two-component system intended for ultra-low-VOC primers. To help limit film fogging and slow drying, apply the prepared coating within the recommended temperature range of 15-40°C.

Recommended System for Wood Sealing

EP-8801 is a silicone-modified epoxy resin used as the resin component in a two-component wood sealing primer. Its high cross-linking density is intended to support sealing performance and a warm appearance on wood. The solvent-free formulation is positioned for ultra-low-VOC coating applications.

Mixing and Application Conditions

Combine EP-8801 with OS-8802 at an approximate 2:1 ratio. The formulation may be adjusted based on experimental results. Because the mixed coating is temperature-sensitive, maintain a construction temperature of 15-40°C. Lower temperatures may contribute to a foggy film and extended drying time.

The stated applications include indoor and outdoor wooden furniture. The company's broader application coverage also includes flexible materials such as textiles, printing leather, inks, and adhesives; however, the supplied information does not report performance results for EP-8801 in those uses.

Company and Quality Credentials

Guangzhou Guanzhi New Material Technology Co., Ltd. holds a QUALITY MANAGEMENT SYSTEM CERTIFICATE covering the research and production of environmentally friendly, multi-purpose water-based polyurethane coating materials and high-performance environmentally friendly water-based coating additives. The company also holds a Certificate of Intellectual Property Compliance Management System Certification for relevant research, development, and sales activities. Its customer cases span several industries, including leading paint and coating companies in China, but those cases do not establish specific performance data for EP-8801.

Frequently Asked Questions

Is EP-8801 a water-based PU product?

No. The supplied specifications describe EP-8801 as a solvent-free, silicone-modified epoxy resin, not a water-based polyurethane grade.

What ratio should be used with OS-8802?

The approximate EP-8801-to-OS-8802 ratio is 2:1. The final ratio can be adjusted based on experimental results.

What conditions help reduce fogging and slow drying?

Keep application temperature within the recommended 15-40°C range. According to the product information, temperatures that are too low may lead to a foggy coating film and slower drying.

Selection and Supply Notes

For the documented wood-sealing application, EP-8801 paired with OS-8802 is the specified option when a solvent-free, ultra-low-VOC, two-component primer is required. Maintain the recommended application temperature and confirm the formulation through testing. The stated minimum order quantity is 900 KG, with a delivery time of 7-10 days.
