KD-NSF-FP-STI-A طلاء داخلي غير منتفخ مقاوم للحريق للهيكل الصلب

الوصف

STI-A is a two-component, cement-based, water-based, non-intumescent fire retardant paint for indoor steel structures. Made from non-toxic, odorless, and harmless inorganic materials, it emits zero harmful gases during application, use, or fire exposure.

Key features:

✔ Low smoke & toxicity – Minimal smoke emission (AQ1 certified)
✔ Passive fire protection – Delays heat transfer to steel substrates
✔ Non-combustible & low thermal conductivity – Effectively resists fire for 1-4 hours
✔ Wide compatibility – Works with epoxy zinc-rich primers for optimal adhesion

Certifications & Test Reports

STI-A complies with China’s GB14907-2018 standard, offering certified fire ratings:

• 1.0h, 1.5h, 2.0h, 2.5h, 3.0h, 4.0h

• CCCF certified (China Compulsory Fire Product Certification)

• AQ1 toxicity rating (low smoke hazard)

Substrate Requirements

• Steel surfaces must be sandblasted and coated with:
  ✔ Epoxy zinc-rich primer + epoxy micaceous iron oxide intermediate coat (recommended).

• Incompatible substrates: Uncoated steel or galvanized surfaces (risk of corrosion).

• Pre-construction inspection: Check for cracks, weld defects, dust, or oil residue.

Application Guide

1. Base Layer (Textured):

   • Mix STI-A powder : adhesive = 1:1, add water, and spray to 3–4mm thickness. Cure for 24h.

2. Main Coating:

   • Mix STI-A powder : adhesive = 4–5:1. Spray in 6–8mm layers (0.5–0.6m nozzle distance, 0.6–0.8MPa pressure).

3. Reinforcement:

   • At ~10mm thickness, embed fiberglass mesh (5–10cm overlap).

4. Environment:

   • Temperature: 15–30°C (limits: 5–35°C).

   • Humidity: 10–70% (limits: 0–80%).

Storage & Transport

• Store in dry, ventilated areas (≥5°C).

• Shelf life: 6 months (avoid moisture).

Packaging

Each package includes:

• Fire product ID label (A-tag) + verification label (B-tag).
