Quality Control

At Wayen, quality is not just a step in our production—it is the foundation of our brand.
We follow a strict and traceable quality management system to ensure every batch of coating delivers consistent performance, safety, and reliability.

• We only work with certified and reputable suppliers.

• All raw materials—resins, pigments, additives—must pass incoming inspections before entering storage.

• Each batch is evaluated for purity, stability, and environmental compliance.

Key checks include:
✓ Appearance and purity
✓ Viscosity and solid content
✓ pH value
✓ Environmental safety (VOCs, heavy metals, odor)

Wayen’s R&D team conducts repeated formula optimization and stability testing before any product enters mass production.

Laboratory tests include:

• Film hardness & adhesion testing

• Chemical resistance

• Water resistance & moisture aging simulation

• UV & outdoor weather resistance

• Scrub resistance, stain resistance

• Temperature and freeze–thaw cycles

Every approved formula must meet Wayen’s internal standards—often stricter than industry norms.

Our production follows a controlled procedure with full-record traceability:

1. Material weighing & proportioning

2. High-speed dispersion & grinding

3. Fine filtration

4. Defoaming & stabilization

5. Final blending & quality inspection

Each step is monitored by experienced technicians to ensure consistency, uniformity, and safety.

Throughout the production cycle, we perform multiple on-site checks, including:

• Viscosity monitoring

• Particle fineness testing

• Color consistency and tint strength

• Density, pH, and solid content

• Film forming and drying behavior

Any abnormal data automatically triggers a re-evaluation and adjustment process.

Before packaging, each batch must pass a full set of tests:

• Adhesion

• Hardness

• Coverage and gloss

• Odor level

• Waterproof, anti-slip, or special performance (depending on product)

• Compatibility with different substrates

Only batches that reach the standard receive a QC release certificate.

• Each container is labeled with batch number, production date, and inspection record.

• Packaging is checked for sealing, durability, and transport safety.

• Every batch is traceable back to raw materials and production personnel.

We maintain a retained sample from every batch for at least 12 months to monitor long-term stability.
Customer feedback is recorded and linked back to production data to ensure rapid response and ongoing improvement.

Wayen strictly adheres to environmental standards for water-based coatings:

• Low VOC

• Non-toxic, odor-reduced formulas

• No heavy metals or harmful substances

• Compliance with international environmental requirements (EU, US standards, where applicable)

Every batch tested.
Every detail controlled.
Every product safe, stable, and reliable.

Wayen is committed to delivering coating solutions with consistent high performance—trusted by both professionals and homeowners.
