Application : General adhesive
use, EPI wood adhesive..
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 tack. 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 plasticizers 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 characterized by its
low surface tackiness, good resistance against water, solvents, alkali,
light and general aging. 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 high
load of fillers, e.g. types like calcium carbonate, clay, shellor wood
flour. If 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 stabilized by PVA as 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
equipments should be immediately cleaned up with warm water
Packaging : 220 kg Iron Drum.
Safety & Storage : In
general, EVA-VC is considered safe for their intended use. However, since
these products contain minor amounts of residual vinyl acetate monomer, it
is recommended that adequate ventilation is provided in room where EVC-VC is
handled. Usual protective measures when handling emulsion such as wearing
gloves and goggles should be observed. Splashes on the skin or in eyes
should be immediately removed by irrigation with clean water. After delivery
ex production site the emulsion must be stored in its properly closed
original containers in sheltered areas at cool temperatures (5-30 oC). For
maximum shelf life, please refer to the label. Protection against frost is
mandatory.
