Key Features
- IMO FTP Code Part 5 & 6 compliant fire performance
- Isophthalic base for marine-grade water resistance
- Halogen-free flame retardant chemistry
- Available with Lloyd's Register, DNV GL type approval
- Compatible with ATH filler for enhanced fire performance
Fire Retardant UPR for Marine combines an isophthalic polyester backbone with reactive halogen-free flame retardant chemistry to deliver both the hydrolytic resistance required for marine service and the fire performance mandated by IMO Resolution MSC.307(88) and SOLAS regulations for commercial vessels, ferries, and offshore platforms.
The resin incorporates a combination of phosphorus-containing reactive monomers and alumina trihydrate (ATH) filler compatibility to achieve LOI >28% and pass IMO FTP Code Part 5 and Part 6 fire tests for interior hull structures. The isophthalic base ensures water resistance equivalent to standard marine-grade UPR, preventing delamination and osmotic blistering in below-waterline applications.
Viscosity at 25°C is 350-600 mPa·s, suitable for hand lay-up and spray-up of hull linings, interior panels, and structural bulkheads. Gel time with standard MEKP is 15-25 minutes. Cured flexural strength is 90-110 MPa. Classification society type approval documents (Lloyd's Register, DNV GL, Bureau Veritas) are available upon request. Suitable for passenger vessels, ferries, naval craft, and offshore structures.

Applications
FAQ
With proper laminate construction (min. 6 mm thickness, 25-30% glass content), this resin enables compliance with: IMO FTP Code Part 5 (surface flammability) and Part 6 (smoke and toxicity) for interior hull structures on commercial vessels under SOLAS Chapter II-2. Type approval certificates are issued by recognized classification societies after full-scale fire tests per the FTP Code procedures.
