Laminated plastic sheets

Once dried, the treated paper or cloth is fairly stable and, stored in a cool place, it may be kept for several weeks or months before pressing into laminated plastic sheets. 

The conditions to be met in decorative printing are particularly demanding. Decorative papers for gravure and flexographic printing are used to produce laminated plastic sheets. Pigment selection is a matter not only of the type of resin (melamine or polyester), but also a function of the processing method. 

Various disazo condensation pigments are utilized in decorative printing on laminated plastic sheets. They are also applied in a number of special-purpose media outside the above-mentioned groups, such as oil colors for artists and crayons. 

The list of applications also includes decorative printing inks for melamine based laminated plastic sheets. It should be noted, however, that P.B.15 1 may not be used in decorative printing inks for polyester-based sheets, because the pigment... 

The list of applications also includes printing inks, in which P.Gr.36 is tinctori-ally weaker than its copper phthalocyanine counterparts. For comparison, 1/3 SD letterpress proof prints containing P.Gr.36, printed at standardized film thickness, require approximately 26% pigment, while only 17% of P.Gr.7 suffice for the same purpose. The fastness properties exhibited by P.Gr.36 in prints, as in paints, closely resemble those of P.Gr.7, including the phototropic behavior of decorative printing inks for melamine-based laminated plastics sheets. 

The list of applications also includes decorative printing inks for laminated plastic sheets based on melamine or polyester resin. The required fastness and performance properties are very good the pigment does not, for instance, color the clear sheets. 8% gravure prints (20 pm cell depth) equal step 8 on the Blue Scale for lightfastness.

These adhesives are compatible with a wide range of wood and wood-associated materials such as the common laminated plastics sheets and are effective on absorbent protein-based and cellulose- based materials, but unsuitable for thermoplastics. Almost invariably one surface must be absorbent. 

Laminating plastics sheet and the bonding of an extremely wide variety of materials - particularly where flexibility is required and the operating environment is not too demanding. Vulcanised versions will perform well in bad environments and will sustain substantial loads. 

Phenolic resins are generally used in alcohohc solution, whereas melamine resins are best handled in water or water-alcohol mixtures. The paper or cloth web is passed through a dip tank containing resin solution, adjusted for pickup on squeeze rolls, and then passed through a heated dr3ung oven. Once dried, the treated paper or cloth is fairly stable and, if stored in a cool place, it may be kept for several weeks or months before pressing into laminated plastic sheets.
