X-8380 Hot Spray Polyurea Coating
X-8380 Solvent-Free 2K Hot Spray Polyurea Coating

Product Info
X-8380 is a fast-curing, solvent-free aromatic polyurea elastomer coating engineered for critical waterproofing and corrosion protection. Compliant with Chinese National Standard GB/T23446-2009 Type II, it forms a seamless, flexible barrier on primed steel, concrete, and other substrates. Designed exclusively for 1:1 ratio dual-component spray equipment, it achieves rapid film formation (surface dry: 60 sec at 24°C), drastically reducing project downtime in demanding environments like water tanks, granulation towers, and underground structures.

Application
1. Surface Preparation
- Apply only on pre-treated, primed substrates.
- Seal joints/gaps with compatible sealants; pre-treat corners/seams with waterproofing tape.
2. Environmental Conditions
- Do not apply when:
- Ambient temperature <4°C or >38°C
- Rain expected within 30 min or humidity >90%
3. Spray Parameters
- Equipment: 1:1 ratio dual-component airless spray rig
- Dry Film Thickness (DFT):
- Light wear: 800–1000μm
- Moderate wear: 1000–1500μm
- Severe wear: 1500–3000+μm
- Recoat window: <5 min between passes (at 24°C)
4. Quality Control
- Inspect for voids/pinholes; repair defects within 48 hours.
- Use X-7109 repair material for patching (feather edges for seamless integration).
5. Topcoat Recommendation
- For UV stability or aesthetic needs, apply a UV-resistant topcoat (contact ISOPOLYOL for options).
