Plastisol is a dispersion of P.V.C. resin. (polyvinyl chloride) in a plasticizer with other additives. It is a whitish liquid (when there is no pigment), with variable viscosity. This general name covers an almost infinite number of formulas which have one basic common point: under the action of heat (160 - 200ºC) they leave their initial liquid state, going into a solid state without loss of weight or notable change in volume.

2. DIP MOULDING.
3. MONOMER CASTING.
4. ROTATION MOULDING.
5. TEXTILE COVERING.
To encourage the adhesion of plastisol to metal parts it is necessary to give them a special priming. Depending on the kind of part to be plasticized, you can choose between two compounds:
PRIMER SY - 100:
It is generally used for adhesion to metal parts, particularly iron, which do not need special treatment.
PRIMER SY - 200:
It is generally used for adhesion to metal parts for subsequent galvanising treatment (with chrome, zinc, cadmium...).
TECNYFLEX is a vinyl resin appearing in the form of an elastic, thermoplastic, rubbery-looking mass that melts at a temperature of 80ºC.
TECNYFLEX allows you to make flexible moulds for casting plaster, plaster of Paris, artificial stone, prefabricated concrete pieces and pieces of polyester resin.
Moulds made with TECNYFLEX can be recovered and melted down again several times with very little loss of the material's properties, making it a very economical product.
METHOD OF USE:
TECNYFLEX melts at 80ºC, going from a solid to a liquid state. It is advisable to melt it at above 150ºC-180ºC, which achieves greater fluidity, making it set better and preventing the formation of bubbles. It can be melted using direct heat, in an oil bain marie or in an oven at a maximum of 200ºC.
Before removing it from the mould it is essential that it has completely cooled, in order to prevent deformation in the mould.
In its melted state, TECNYFLEX has a low viscosity, which facilitates setting and perfect reproduction of the model.
Mould release agents are not necessary.
Good resistance to tearing.
The time required to make the moulds is minimal and reproduction is immediate.
It is advisable to apply a coat of shellac or a porous cellulose cover to the original model.
HANDLING AND PRECAUTIONS
It is advisable to melt it in clean receptacles without remains of other products.
Take the precaution of melting it in ventilated places with fume extraction. The vapours it gives off are those of plasticizers, which are not considered toxic,
but which can irritate the airways, so we recommend that it is not melted at above 200ºC.
If melted using direct heat, take the precaution of putting a metal plate between the heat and the receptacle so that the remains sticking to the pan do not come into direct contact with the heat source.
If it comes into contact with the skin during melting, rinse immediately with cold water and carry out burns treatment.
- PLASTISOL FOR TEXTILE PRINTING
Printing inks for textile coverings printed either directly or using a transfer system.
T-shirts, sportswear, sweatshirts, heat transfer, flock, etc..
Good resistance to washing.
They do not dry in air so long runs can be printed without cleaning screens.
Great stability on the screen.
TECNYSOL inks are suitable for printing the majority of natural and synthetic fibres either using direct printing or heat transfer on silicon paper.
