Overview
ZC-44 is a general-purpose liquid bisphenol-A epoxy resin manufactured from bisphenol-A and epichlorohydrin, part of the Polylite product line in our resin range. It is recognized as a standard grade from which many variations have been developed, and is supplied with supply chain resource support for formulators sourcing a versatile epoxy resin for coatings, adhesives, and composite applications.

Applications of ZC-44 Across Coating and Composite Systems
This resin is suitable for adhesives, filament winding, casting and tooling, civil engineering applications, composites, automotive coatings, can coating, coil coating, and marine and protective coatings. Its higher epoxy equivalent and viscosity compared to standard low-viscosity grades make ZC-44 a common choice where formulators need a resin base for coating and protective-film applications alongside structural composite work.
Curing Options for ZC-44
This resin can be cured with a wide variety of curing agents at ambient conditions, most commonly aliphatic polyamines, polyamides, amidoamines, cycloaliphatic amines, and modified versions of these curing agents. These systems are sometimes cured at elevated temperature to improve selected properties such as chemical resistance and glass transition temperature. Elevated-temperature cures and long post-cures are required to develop full end properties if anhydride or catalytic curing agents are employed.
Why Sourcing Consistency Matters for Buyers
Because epoxy equivalent, viscosity, and chlorine content directly affect curing behavior and finished-part performance, buyers should confirm current specifications for this resin against the latest technical data sheet before scheduling a production run. A supplier that consistently delivers this resin within its stated epoxy equivalent and viscosity range reduces the need to re-qualify a curing recipe with every new batch.
This is particularly relevant for coating formulators and composite manufacturers, where epoxy equivalent and chlorine content are directly tied to cure chemistry and long-term coating or part performance. Buyers should confirm current batch documentation against the latest technical data sheet before finalizing a production schedule.
What to Consider When Sourcing ZC-44
Buyers evaluating ZC-44 for the first time should confirm that its epoxy equivalent (450-500 g/mol) and viscosity (8000-15000 mPa•s at 25℃) match their curing agent selection and process requirements, and should review whether ambient or elevated-temperature curing best fits their coating or composite application. Requesting the current certificate of analysis alongside the technical data sheet is a practical way to confirm that a given batch matches the specifications listed above.
Packaging, storage temperature requirements, and shelf life should also be confirmed directly with the supplier, since these factors affect how this resin performs once it reaches a production facility. Buyers sourcing this resin for time-sensitive production schedules should discuss lead time and logistics requirements before finalizing an order.
General Handling and Storage Guidance
As with other bisphenol-A epoxy resins, ZC-44 should be stored in accordance with the supplier’s technical data sheet, typically in a cool, well-ventilated area away from direct sunlight and sources of heat or ignition, since elevated storage temperatures can affect the resin’s viscosity over time. Personnel handling this material should follow the handling procedures specified in the safety data sheet.
Buyers should request and review the current safety data sheet for this resin prior to receipt, and confirm that on-site storage conditions are compatible with the supplier’s recommended shelf life and temperature range. Proper inventory rotation helps maintain the epoxy equivalent and viscosity described above.
