PRODUCTION OF ELASTOMERIC FILMS

A method for producing multi-layered elastomeric film or article, the method comprising: (i) dipping a mould into a composition for producing an elastomeric film having a total solids content of between 5 % - 40 % to produce a layer of elastomeric film composition on the mould, (ii) partially drying...

Summary:A method for producing multi-layered elastomeric film or article, the method comprising: (i) dipping a mould into a composition for producing an elastomeric film having a total solids content of between 5 % - 40 % to produce a layer of elastomeric film composition on the mould, (ii) partially drying the layer of elastomeric film composition on the mould to reduce the total water content of the elastomeric film composition to a level of not less than 22 %, (iii) dipping the mould coated with the partially dried layer of elastomeric film composition into a composition for producing an elastomeric film having a total solids content of between 5 % - 40 % to produce a further layer of elastomeric film composition on the mould, (iv) optionally repeating the partial drying step (ii) and the further dipping step (iii), and (v) drying and curing the layers of elastomeric film composition on the mould.
