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 Epoxy Equivalent Weight (EEW) 1800 ~ 2500 g/eq Softening Point 130 ~ 150 ℃ Solution Viscosity (40% Xylene, 25℃） Z2 ~ Z5 Gardner Viscosity Gardner Color ≤1.0 Volatile Content ≤0.8 % Physical Form Transparent solid flakes Standard Pack 25kg/bag CAS No. 25036-25-3   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.
