Can a Supplier Store Epoxy Resin Before Shipment?

Warehouse Storage Requires Prior Confirmation

A supplier may be able to keep epoxy resin at its warehouse before shipment, but this arrangement must be confirmed in writing. The available product information does not identify warehouse holding as a standard service or specify the conditions for supplier-managed storage.

There is also an important product-identification issue. The referenced material is PA-3330, described as a water-based hydroxy-functional acrylic dispersion rather than epoxy resin. It is intended for water-based two-component coating systems and is mentioned in connection with waterborne 2K epoxy primer applications.

What Buyers Should Verify

• Ask the supplier whether the material can remain in storage after production and before dispatch.
• Confirm the exact product name, grade, quantity, and intended coating application.
• Agree on the maximum holding period, storage requirements, release date, and responsibility for product condition.
• Check whether warehouse storage affects the stated shelf life or delivery schedule.
• Use the available 7–10 day delivery estimate when organizing purchasing and logistics.

Product and Logistics Information

The product record lists a minimum order quantity of 900 KG and a delivery lead time of 7–10 days. Available transportation options include sea freight, air freight, express courier, and rail freight, depending on the buyer's requirements. These details can support shipment planning, but they do not prove that the supplier will hold completed goods without a separate agreement.

PA-3330 is presented as a binder for water-based two-component coatings. Its reported performance includes resistance to water, alkali, and acid, together with high gloss, strong fullness, good appearance, smooth leveling, and the ability to form a blister-free film at suitable thicknesses. Listed wet-on-wet systems include a waterborne 2K PU topcoat combined with either a waterborne 2K epoxy primer or a waterborne 2K PU primer.

Shelf Life and Storage Responsibility

The stated shelf life for PA-3330 is 12 months. However, the supplied information does not define warehouse temperature, packaging requirements, inspection procedures, or any extension of shelf life when the product remains at the supplier's facility. Buyers should therefore obtain written terms before scheduling delayed shipment.

Supplier Capabilities and Quality Information

Guangzhou Guanzhi New Material Technology Co., Ltd. describes an R&D, manufacturing, sales, and technical service model. The company provides technical support and free reference formulations. Its listed application sectors include rail transit, engineering machinery, steel structures, automotive components, and indoor or outdoor wooden furniture.

The company also lists a Quality Management System Certificate related to the research and production of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance water-based coating additives. An Intellectual Property Compliance Management System Certification is also identified. Cooperation cases involving PPG and Nippon Paint are listed for coating-related applications.

Key Data for Shipment Planning

Frequently Asked Questions

Is it possible to keep epoxy resin at the supplier's warehouse before shipment?

It may be possible, but the available information does not confirm this service. The buyer should receive direct written approval before asking the supplier to delay dispatch.

Is PA-3330 an epoxy resin?

No. PA-3330 is identified as a water-based hydroxy-functional polyacrylic secondary dispersion. It can be used in coating systems that reference waterborne 2K epoxy primers, but that does not make the material itself an epoxy resin.

What are the main ordering details for PA-3330?

The listed minimum order is 900 KG, the indicated lead time is 7–10 days, and shipment can be arranged by sea, air, express courier, or rail freight based on the customer's requirements.

Conclusion

Pre-shipment storage at the supplier's warehouse cannot be confirmed from the available product data. Before placing an order or postponing dispatch, request written confirmation of the storage period, conditions, product responsibility, release schedule, and shelf-life treatment. Also verify the material identity, since the referenced product is PA-3330 water-based hydroxy acrylic dispersion rather than epoxy resin.
