Overview
AME 5500-60/90RT is a modified vinyl epoxy resin developed by INEOS Composites exclusively for marine infusion application. This resin is supplied with supply chain resource support for formulators sourcing a resilient, blister-resistant infusion resin with excellent fatigue life and toughness for demanding marine laminate construction.
AME 5500-60/90RT can be specified for the construction of marine laminates where low shrinkage, improved strength, impact resistance, blister resistance, and profile are required. The physical properties of cured laminates made with this resin outperform conventional polyester resin systems, and it displays excellent wet-out and handling characteristics under a variety of shop conditions.
Applications
AME 5500-60/90RT is developed by INEOS for marine infusion application and big FRP tooling. The 60RT and 90RT designations refer to two gel-time grades of the same resin chemistry, allowing fabricators to select the reactivity that best matches the size of the infusion and the working time needed to achieve complete wet-out before gelation begins.
Specification of AME 5500-60/90RT (Uncured Resin)

Why Blister Resistance and HDT Matter for Marine Infusion
Blister resistance is one of the key properties formulators reference when a marine laminate needs to perform in continuous water immersion, since osmotic blistering below the laminate surface is one of the most commercially damaging defects in FRP boat building. AME 5500-60/90RT is engineered for resilience and blister resistance, which helps reduce moisture-related failures over the vessel’s service life.
With a Heat Deflection Temperature of 86°C as cast and up to 108°C post cured, this resin retains structural performance at elevated service temperatures, which is relevant for hull and deck laminates exposed to sustained sun and engine-room heat. Combined with 140.1 MPa flexural strength and 5.28% elongation at break, the resin balances stiffness with toughness for impact resistance in structural marine laminates.
What to Consider When Sourcing AME 5500-60/90RT
When sourcing an infusion resin for marine laminates or large FRP tooling, formulators typically evaluate viscosity and gel time against panel size and infusion strategy, alongside HDT and flexural/tensile performance for the target structural specification.
Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new resin grade for a production line. Because gel time and peak exotherm are tested under specific catalyst and temperature conditions, buyers should confirm these process parameters against their own infusion setup and ambient shop temperature before finalizing a production schedule.
Curing and Fabrication Considerations
Choose the 60RT grade (75-minute gel time) for smaller infusions or shop conditions where a faster cycle is needed, and the 90RT grade (105-minute gel time) for larger panels and complex tooling where extended flow time is required to achieve complete wet-out before gelation. Fabricators typically run a small trial infusion to confirm gel time and cure behavior under their own shop temperature before scheduling a full production run, since catalyst level and ambient temperature affect working time.
Certifications and Commercial Warranty
The manufacturing, quality control and distribution of AME 5500-60/90RT comply with one or more of the following programs or standards: Responsible Care, ISO 9001, ISO 14001, and OHSAS 18001. The product carries a commercial warranty of three months from the date of manufacture, when stored in accordance with the recommended storage conditions.
General Handling and Storage Guidance
Store AME 5500-60/90RT in IBCs and drums at a temperature below 25°C. Storage life decreases with increasing storage temperature, so avoid exposure to heat sources such as direct sunlight or steam pipes. To avoid contamination of the product with water, do not store outdoors, and keep containers sealed to prevent moisture pick-up and monomer loss. Mild mixing is recommended after prolonged storage, and stock should be rotated so older material is used first.
