Colloidal varnish for decal
Colloidal varnish for decal – the special type of a varnish intended for carrying the image over from a paper on a product and giving to a product after roasting brightness and surface shine.
Various manufacturing techniques use colloidal varnish for transferring an image onto ceramic, metal-ceramic, glass or other surfaces. The most common techniques are the silk screen method, decal on laser printer and hand painting on decal paper. After the image is put on decal paper and is covered by a colloidal varnish, it is transferred onto a surface of ceramic, enamel, photo ovals or glass. Then the product is fired in a muffle furnace, where the varnish dries out and the paint bakes into the product surface. A great advantage of using decals for photoceramics is that a decal can be applied to a product having a different shape, such as plain, cylindrical or on convex and concave surfaces.
The correct choice of a colloidal varnish for decal prevents common problems such as two-tone in the image, occurrences of micro cracks on the image, occurrences of micro cracks on the image, ruptures after soaking pictures and its carrying over on a product.
