Overview
VAE emulsion is short for ethylene acetate-ethylene copolymerization emulsion, which is a polymer emulsion made of ethylene acetate and ethylene monomer as the basic raw materials and other auxiliary materials through emulsion polymerization. Ethylene and vinyl acetate copolymer is the most important product of ethylene copolymer, generally referred to as EVA.
Products with ethylene acetate content in the range of 70%~95% are usually in the emulsion state, called VAE emulsions.
Product name: Vinyl Acetate Ethylene Copolymer Emulsion
Other name: Vinyl acetate-ethylene copolymer emulsion, VAE emulsion, VAE dispersion, Ethylene-vinyl acetate copolymer emulsion, EVA emulsion, Ethylene-vinyl acetate copolymer dispersion, EVA dispersion.
Appearance: VAE Emulsions are milky white or yellowish.

Storage
1. Temperature:
Store VAE emulsion in a cool and stable temperature environment. Avoid exposure to extreme temperatures, both high and low, as this can affect the stability of the emulsion.
Generally, a temperature range of 5°C to 30°C (41°F to 86°F) is recommended.
2.Avoid Freezing:
Protect VAE emulsion from freezing temperatures. Freezing can lead to irreversible changes in the emulsion's structure, resulting in a loss of performance.
If the emulsion has been exposed to freezing conditions, it is advisable to thoroughly mix and test it before use.
3.Containers:
Store VAE emulsion in tightly sealed containers to prevent air exposure. This helps to avoid evaporation of water and maintains the stability of the emulsion.
Ensure that containers are kept in an upright position to prevent leakage and contamination.
4.Ventilation:
Store VAE emulsion in a well-ventilated area to prevent the buildup of heat and humidity. Adequate ventilation helps maintain the quality of the emulsion over time.
5.Protection from Sunlight:
Shield VAE emulsion from direct sunlight or ultraviolet (UV) radiation. Prolonged exposure to sunlight can potentially degrade the polymer and impact the emulsion's performance.
6.Avoid Contamination:
Prevent contamination by using clean equipment and tools when handling or transferring the emulsion. Contaminants can affect the properties of the emulsion.
7.Regular Inspection:
Periodically inspect stored VAE emulsion for any signs of separation, coagulation, or other abnormalities. If any issues are identified, investigate the cause and take corrective action as needed.
8.First In, First Out (FIFO):
Use a first-in, first-out system to ensure that older batches of VAE emulsion are used before newer ones. This helps prevent extended storage periods and maintains product freshness.
9.ElephChem's Recommendations:
Always refer to the specific recommendations provided by the ElephChem for the storage and handling of the particular VAE copolymer emulsion you are using. Different formulations may have specific requirements.
Frequently Asked Questions (FAQ)
Q: What is VAE Emulsion?
A: VAE Emulsion (Vinyl Acetate-Ethylene copolymer emulsion) is an eco-friendly waterborne binder synthesized by copolymerizing vinyl acetate and ethylene monomers under high pressure. Ethylene acts as an internal plasticizer, eliminating the need for external plasticizers.
Q: What is the main difference between VAE Emulsion and Pure PVA / Acrylic Emulsions?
A: VAE vs. PVA (Polyvinyl Acetate): Traditional PVA requires added plasticizers (like phthalates) to stay flexible and has limited water resistance. VAE uses internal ethylene plasticization, making it permanently flexible, zero-phthalate, and significantly better in adhesion and water resistance.
VAE vs. Pure Acrylic: Pure Acrylics offer higher UV and outdoor weatherability, but VAE provides superior wet-tack, stronger adhesion to difficult substrates (like plastic/metal films), better cost-efficiency, and inherently lower VOC emissions for indoor use.
Q: Is VAE Emulsion environmentally friendly and compliant with low-VOC regulations?
A: Yes. VAE emulsion is widely recognized as an eco-friendly binder. Because it is water-based and internally plasticized, it contains no APEO (Alkylphenol Ethoxylates), no formaldehyde (or ultra-low residual), and no phthalate plasticizers. It inherently complies with strict global environmental regulations such as REACH, RoHS, China Ten-Ring Certification (HJ 2537), and Blue Angel, making it the primary choice for indoor zero/low-VOC formulations.
