VINAVIL EVA 203 is a vinylacetate-ethylene copolymer with excellent adhesion to plastic materials and
an high cohesive strength. These features make it suitable for prepare adhesives used for bonding
plastic foil to wood and it fibre boards where resistance to high and low temperatures and creep are
required.
VINAVIL EVA 203 shows a pseudo-plastic rheological behaviour which makes it particularly suitable for
high speed machines. It can be modified by adding plasticizers (dibutylphtalate) or coalescing agents
(diethylene glycol monobutyl ether acetate). The addition of such additives brings to an increase in
viscosity of the emulsion and improves adhesion at low temperature without significantly lowering heat
and creep resistance.
VINAVIL EVA 203 can be formulated with mineral fillers, such as calcium carbonate and calciumsulphate,
without significant performance reductions.
Due to the quick setting time VINAVIL EVA 203 can be used either to glue paper with plastic sheets and
overlacquered papers, also with high-speed machines.
COMPATIBILITY
VINAVIL EVA 203 is compatible with the components usually employed in vinyl-ethylene copolymers
based aqueous adhesives such as:
- acrylic and cellulosic thickeners
- plasticizers such as benzoic acid esters and polymeric esters, triacetin
- tackifiers, such as natural and modified rosin, coumarone-indene, terpene and hydrocarbon resins.
