1.EVA emulsion is vinyl acetate/ethylene copolymer emulsion which is a kind of adhesive with excellent performance. Compared to PVAC emulsion ,the
flexility,weather-resistance and waterproofing of VAE copolymer have been largely improved.
2.The VAE emulsion of hanwei brand has permanent flexility/well acidity-alkaline resistance and excellent solubility.It doesn't lead to agglomeration phenomenon when mixed with most of additive\pigment and filler;It can also mix directly with many water-based low-molecular and macrololecule .Meanwhile ,Our VAE emulsion is UV-resistance and excellent film-forming.Our product is non-toxic and tasteless,pollution-free,completely be in line with mordern environmental requirement.
3.VAE emulsion is widely used in adhesive , paint ,coating, modified cement , textile and process paper and so on.This kind of product belong to water-based adhesive,it has passed FDA(Food And Drug Management Department Of Ameria) certification,therefore,it can use as adhesive in food package.
