Hangzhou Kewang Special Ink Co., Ltd. combines photosensitive development process with water transfer technology, and newly developed photosensitive development type anti-sanding ink LPR-863BL. It is mainly used for high-precision, small-batch, multi-species, personalization, plane or curved surface. The production of sand carving handicrafts has excellent adhesion fastness and sandblasting resistance to mirror metal, ceramics, glass, marble, wood and other materials. The process flow is as follows: water transfer papers → printing or roller coating anti-sanding photosensitive inks → drying → photopolymerization → development → drying → printing cover oils → water transfer anti-sanding engraving patterns → sandblasting → photo-removal film removal → fine sand engraving products . The advantages of LPR-863BL are as follows. 1. Low cost, high resolution, excellent sandblast resistance. The sand-resistant water-cut transfer paper produced using water-developed photosensitivity anti-sanding ink is approximately 1/3 to 1/2 the cost of sand-engraved film, and its resolution and sandblasting resistance are the same as those of plastic anti-sanding film. Can reach a very high level. 2. Easy to use, no glue paste. Developed good anti-sand carved water transfer paper, after wetting in water, the photosensitive pattern is automatically separated from the backing paper, and can be directly affixed to the product without the need of brushing glue, and can be sandblasted after drying. 3. High yield. The self-adhesive water-soluble adhesive layer on the water transfer paper can make the anti-sand carving patterns firmly stick to a variety of substrates to ensure that the anti-sanding photosensitive patterns will not float due to poor adhesion, which greatly improves the finished product. rate. 4. Green. Photosensitive ink uses pure water as a solvent and does not contain any organic substances. No organic solvents are emitted during printing, drying, sensitization, development, and pasting.
