AME VPRO 03 S is a marine gel coat from INEOS Composites, formulated with epoxy vinyl technology to give hull surfaces a durable, good-looking finish while helping composite fabricators manage energy use and production costs. For yacht builders and mold manufacturers comparing gel coat options, this product’s documented viscosity, cure and mechanical properties offer a useful reference point before placing an order.
AME VPRO 03 S Product Overview
According to the INEOS technical datasheet, this gel coat is designed with epoxy vinyl technology so that the hull surface achieves good performance while helping fabricators save energy and minimize production costs. It is positioned for industrial products such as yachts that require good surface properties, as well as for mold manufacturing of various products.
Uncured Gel Coat Properties of AME VPRO 03 S
Per the manufacturer’s datasheet, the following nominal properties apply to the uncured resin at 23°C:
- Viscosity, Brookfield (RV4/10rpm): 10,000 mPa·s (ISO 2555)
- Viscosity, Cone & Plate (ICI): 300 mPa·s (ISO 2884)
- Styrene content: less than 35% (ISO 4864)
- Gel time: 12 minutes (internal method D 006)
These figures help fabricators plan application windows and workshop conditions before committing a batch of this gel coat to a mold or hull surface.
Cured Laminate Properties
When cured with 2% MEKP catalyst for 24 hours at 23°C followed by 16 hours at 40°C, the datasheet lists the following typical properties for the cured gel coat film:
- Tensile strength: 72 MPa (ISO 527-2)
- Tensile modulus: 3300 MPa (ISO 527-2)
- Elongation at break: 6.3% (ISO 527-2)
- Flexural strength: 119 MPa (ISO 178)
- Heat deformation temperature (1.8 MPa): 69°C (ISO 75)
- Barcol hardness: 32 (ASTM D 2583)
- Water absorption (7 days/24 hours): 34/10 mg, as listed in the datasheet (ISO 62)
This combination of hardness, flexural strength and heat resistance is consistent with how AME VPRO 03 S is positioned: a surface coat for yacht hulls and molded parts rather than a general-purpose laminating resin.
Application and Handling
Composite fabricators using this gel coat should stir it thoroughly before use to avoid introducing air bubbles, and should keep the workshop, materials and tools at 18â25°C with relative humidity below 80%. The recommended MEKP (methyl ethyl ketone peroxide) catalyst dosage under these conditions is 1.5â2.5%. Gel coat should be stored below 25°C away from light for a maximum of three months. Buyers can review a current hazard communication and safe-handling reference alongside the INEOS Material Safety Data Sheet before storing or processing this product at their facility. For detailed operating conditions, INEOS directs users to its Gel Coat User Guide.
