Ethylene Vinyl Acetate (EVA) copolymer is a redispersible polymer, available as a free flowing powder that can easily be redispersed to form a latex dispersion!
Some applications require a 100% dry solids polymer that can be pre-mixed with other solid additives. Addition of water to the mixture allows the polymer to re-disperse back into a latex polymer forming a final composite that is adhesively bonded by the polymer in the mixture.
Composition: Ethylene-Vinyl Acetate Copolymer with approximately 20 weight % ethylene and 80 weight % vinyl acetate
Stabilization: The powder is stablized with a vinyl alcohol to allow it to remain free flowing but easily redispersible in water
Solids Content: 99 +/- 1%
Particle Size: 1-7 micron dominant sizes; max 4% over 40 mesh
Glass Transition: - 7°C (Soft, flexible polymer) (Tg°C)
Just add water to this solid grade polymer and it quickly responds by dispersing into latex particles that are useful bonding agents in composites. After evaporation of the water, a solid article may be formed from admixtures of the polymer and other solid components.
