We provide EVA - VC Adhesive to our clients.
Composition: Vinyl Acetate-Vinyl Chloride-Ethylene Terpolymer
Characteristics: EVA-VC is a terpolymer of vinyl chloride, vinyl acetate and ethylene with high thickening response and distinguished wet track. The emulsion is suitable for general adhesive use, especially for high-speed lamination work and where fire retardance is necessary. Because of its low Tg / MFFT, a homogeneous film is formed without any addition of solvents or plasticisers at temperatures even down to 0 oC. The transparent film is the softest among the whole series of our EVA-VC products and is further characterised by its low surface tackiness, good resistance against water, solvents, alkali, light and general ageing. EVA-VC is a recommended base for the formulation of "Emulsion Polymer Isocyanate" (EPI) wood adhesives, even meeting class D4 (boiling water resistance) of the European Standard DIN EN 204, suitable also for a broad variety of different wood species.
Compounding: EVA-VC accepts a high load of fillers, e.g. types like calcium carbonate, clay, shellor wood flour. If the lower viscosity is demanded, it can, of course, be adjusted by carefully adding water to the formulation. The emulsion is best compatible with cement, which can be directly blended in, without any build up of lumps or agglomerates. EVA-VC being stabilised by PVA as a protective colloid is miscible with all other non- and anionic-stabilized emulsions of our DA-series, but trials should always be carried out before mixing it with other polymer dispersions. Note, that resulting films formed from those mixtures may become hazy when different emulsions with a different refractive index are used. For high viscosity applications, PVA or polyurethane/polyacrylic based thickeners show good effects.
Cleaning: Machines, tools and equipment's should be immediately cleaned up with warm water
