Isophthalic polyester (ISO) – general purpose grade resin suitable for minimal contact with harsh chemicals

We offer various anti-slip grit finishes designed to match your environment:
Fine Grit (125-210 µm | Approximately P120–P80 to FEPA Classification): Barefoot-friendly and comfortable underfoot, perfect for public walkways, aquatic areas, schools, and anywhere people may be in lighter footwear or barefoot.
Medium Grit (600 µm | Approximately P40 to FEPA Classification): The trusted choice for general, commercial, and industrial use, providing reliable slip resistance in workshops, plants, and high-traffic areas.
With both options, you get the right balance of safety, comfort, and performance.

Testing was carried out by SGS. in accordance with ASTM D570-22 on our moulded FRP products manufactured using ISO and VE resin systems.

Test Conditions:

Dried at 50 ± 2 °C for 24 h
Soaked in water at:

• 23 °C for 24 h
• 100 °C for 2 h
• 50 °C for 48 h

Measured Water Absorption (%):

Interpretation:
Results demonstrate consistently low water absorption across all temperature and duration tests, confirming a dense, well-cured laminate structure.
Moisture uptake remained below 1 %, supporting dimensional accuracy, mechanical reliability, and long-term surface integrity.
Performance levels are within the expected range for high-grade structural FRP composites and trend toward the lower end of typical absorption values, indicating slightly improved resistance compared with standard industry benchmarks.

Our colour system utilises a polyester-based pigment dispersion that chemically bonds within the FRP matrix, rather than just coating it. This 100 % solids, low-VOC formulation delivers cleaner processing, longer-lasting colour, and superior UV stability compared to solvent-borne alternatives. It’s a smarter, more sustainable way to colour FRP.

Testing was carried out by SGS in accordance with ASTM D495-22 and ASTM D149-20 on our FRP moulded products manufactured using ISO and VE resin systems.

Test Conditions:

• Dry Arc Resistance (ASTM D495-22)
   • Arcing voltage: 12.5 kV • Electrode gap: 6.35 mm • Environment: 23 °C / 50 % RH
• Dielectric Breakdown (ASTM D149-20)
   • Transformer oil medium • Voltage rise: 3000 V/s • Frequency: 50 Hz

Measured Electrical Performance:

Interpretation:

Results confirm both resin systems deliver high-grade electrical insulation consistent with the requirements of ASTM D495 and D149.
The ISO-resin laminate achieved the highest overall performance, showing extended arc-resistance duration and greater dielectric strength, indicating a dense, well-cross-linked matrix with minimal conductive pathways.
The VE-resin laminate also exhibited strong insulating capability, remaining well within the range expected for premium structural FRP composites.

Electrical performance across both systems supports their suitability for installations requiring high-voltage isolation, reduced surface tracking, and long-term reliability in wet or industrial environments.
