Overview
ZC-915 is a flame-resistant vinyl ester resin with excellent mechanical properties and processing characteristics. As one of the recommended international brand products in our resin range, this resin is supplied with supply chain resource support for formulators sourcing a flame-retardant, corrosion-resistant resin for demanding FRP applications.
This resin can show excellent corrosion resistance in most acid, alkali, and salt environments. It is suitable for laminated linings of various anti-corrosion projects that require flame retardancy, chemical tanks, pipes, plates, and other FRP products and accessories.

Why Limiting Oxygen Index Matters for ZC-915
Limiting Oxygen Index, tested to ISO 4589-2 / GB/T 2406, is one of the key values formulators reference when a laminate needs to meet a flame retardancy specification, since a higher LOI value generally indicates a material that is more resistant to sustained combustion.
With an LOI of 30±2 percent, this resin is positioned for anti-corrosion projects and FRP products where flame retardancy is required alongside chemical resistance.
Because this resin also delivers Heat Deflection Temperature of 90±3°C, it retains structural performance at moderately elevated service temperatures, which is relevant for chemical tanks and pipes that may see periodic thermal exposure during processing or cleaning cycles.
What to Consider When Sourcing ZC-915
When sourcing a flame-resistant vinyl ester resin for chemical tanks, pipes, or anti-corrosion linings, formulators typically evaluate the LOI rating against their required flame retardancy specification, along with mechanical properties such as tensile and flexural strength for the target application.
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 gelation time and viscosity are tested under specific catalyst and temperature conditions, buyers should confirm these process parameters against their own mixing and curing setup before finalizing a formulation schedule.
Common Fabrication Considerations
Fabricators building flame-retardant anti-corrosion linings typically run a small trial laminate to confirm gel time and cure behavior under their own shop temperature before scheduling a full production run, since catalyst and promoter levels affect working time differently depending on ambient conditions.
For chemical tank and pipe applications, layer sequence and glass content also affect the finished laminate’s mechanical and flame retardant performance, so confirming the recommended laminate schedule against the project’s design specification before starting fabrication can help avoid rework.
General Handling and Storage Guidance
As with most vinyl ester resins, this product should be kept in its original, tightly sealed container, stored in a cool, dry location away from direct sunlight and heat sources, and used within the stated shelf life of 6 months when stored below 25°C.
Shelf life and specific storage recommendations vary by batch and packaging format, so formulators should always confirm current shelf life, recommended storage conditions, and any handling precautions against the latest technical data sheet and SDS for the specific batch of ZC-915 they are working with.
