Nan Ya NPES 909 Epoxy Resin - Ultra-High-Molecular Solid Bisphenol A Epoxy for Can Interior & Coil Steel Coatings

Full Name: NPES 909 Ultra High Molecular Weight Solid Bisphenol A Epoxy Resin
High-molecular flexible epoxy resin specially designed for metal packaging can interior coating and continuous coil steel baking coating. Features ultra-high film flexibility, low brittleness and stable long-term storage viscosity, can resist bending & stamping cracking of metal packaging after curing.

Core Technical Parameters

Core Advantages

1. Ultra-long molecular chain structure provides excellent bending & stamping flexibility, coating film no crack after metal can deep drawing & folding processing.

2. Ultra-stable solution viscosity, no sharp thickening after 6 months liquid paint storage, extends finished coating shelf life greatly.

3. Outstanding anti-water, anti-food acid & alkali performance, meets strict barrier requirement for metal packaging interior coating.

4. Low volatile content, low odor during high-temperature baking, minimal solvent residue on metal packaging surface.

5. Compatible with phenolic curing agent, amino resin, matched for high-speed continuous coil coating production line.

Main Application Fields

Core Applications: Metal food can interior anti-corrosion coating, continuous coil steel baking coating, aluminum tin printing baking paint
Compatible Applications: High-flexibility metal stamping part topcoat, anti-rust baking paint for precision hardware
Forbidden Scenarios: Indoor decorative powder coating, low-temperature fast-curing anti-corrosion primer, direct food contact without curing film

Handling Precautions

1. Dissolve in high-boiling mixed solvent (xylene + cyclohexanone) at 80~100℃ for full dissolution; single low-boiling solvent cannot fully dissolve the resin.

2. Matched phenolic curing agent dosage: 12% ~ 20% based on total resin weight, adjust per required flexibility & anti-corrosion performance.

3. Seal storage in constant temperature warehouse below 28℃, prevent long-term high temperature which causes viscosity rising of dissolved liquid paint.

4. Baking condition for can coating: 200\220℃ / 8\12 mins to complete crosslinking and form dense barrier film.
