Waterborne Acrylic Emulsion With Good Water Resistance And Fast Drying For Paper Barrier Coating
This waterborne acrylic emulsion is an APEO‑free acrylic copolymer emulsion specially developed for paper barrier coating, printing inks and coatings for paper and textiles. It adopts a water‑based design and stable polymer formulation, providing reliable film‑forming and barrier properties while meeting environmental requirements. As a high‑performance film‑forming emulsion for paper surface treatment, it forms a uniform protective layer on paper substrates to enhance waterproofness and service stability, supporting high‑efficiency production and safe application in food contact paper containers.

For paper barrier coatingSpecial Feature :
APEO-free, water-resistant, fast-drying, stable and easy to re-dissolveProduct Overview
This product is a milky white liquid with a solid content of 40±1%, pH value 7.0–9.0, minimum film‑forming temperature (MFFT) below 7 °C, and viscosity (Brookfield, 25 °C) lower than 500 mPa·s. It is formulated without APEO, features good water resistance, fast drying and good re‑dissolving abilities, and is stable under proper storage conditions. Recommended storage temperature is 5–30 °C; it can be stored for 6 months at 20 °C in intact original packaging. Avoid freezing, overheating and microbial contamination to maintain stable viscosity, particle size and film‑forming performance.

Key Features
◊ APEO‑free environmental formulation: Free of alkylphenol ethoxylates, compliant with green coating and food packaging requirements.
◊ Excellent water resistance: Forms a dense barrier film on paper surfaces to effectively block liquid penetration and moisture absorption.
◊ Fast drying performance: Accelerates coating line speed and shortens production cycles for high‑efficiency manufacturing.
◊ Good re‑dissolving ability: Supports stable re‑dissolving and reprocessing, improving operation convenience and formulation compatibility.
◊ Low minimum film‑forming temperature: Enables complete film formation at low temperatures, suitable for various paper coating lines.
◊ Stable storage property: Maintains stable viscosity and particle size within the recommended temperature range, resisting coagulation and sedimentation.
