The hottest UV special ink and handicraft producti

Production of UV special ink and handicrafts (Part 2)

IV. production of UV hot stamping varnish, liquid photosensitive hot stamping varnish and art glass

Hot Stamping UV varnish uv-1002n

uv-1002n is a colorless, transparent and low viscosity liquid. UV curing is rapid, and the curing film is bright, flexible, non yellowing, and excellent wear resistance. Its particularity is that the light curing film can be bronzed with electrochemical aluminum bronzing film, and the bronzing process conditions are related to the bronzing film, It can also be used in the thermal sublimation transfer tensile experiment: the tensile experiment is also called the image transfer of stress-strain experimental paper, which is efficient and easy to use

liquid photosensitive hot stamping varnish lpr-808

liquid photosensitive hot stamping ink lpr-808 is a colorless transparent varnish, which is specially used for hot stamping of various heat transfer foils, such as anodized hot stamping foils. This kind of ink has excellent photosensitivity, high graphics resolution (minimum line width 0.05 mm), and good adhesion fastness to various metals, glasses, plastics, films, leather, paper, etc. at the electric vehicle hundred people's meeting held a few days ago. After UV curing, the photosensitive film has the characteristics of high brightness, high hardness, no yellowing and scratch resistance

the uniqueness of the new process lies in: 1. In the hot stamping process, there is no need to make metal relief plate, which has low cost and high speed. As long as there is a positive negative film, hot stamping can be carried out. 2. It is suitable for the production of small batch and multi variety personalized hot stamping products. 3. Low hot stamping temperature (100~130 ℃). 4. Suitable for hot stamping of large area and fine line graphics and texts. 5. Hot stamping substrates are not restricted, such as various plastic films, paper, leather, metal, glass, etc

specific process: leak the lpr-808 wire full-scale or spray it on the substrate to be hot stamping → dry → expose with phenanthrene (after UV exposure, the photosensitive film of the non pattern part becomes thermosetting, and the pattern part is still thermoplastic) → hot stamping (in the process of hot stamping, the adhesive layer of the hot stamping film and the thermoplastic part of the photosensitive film are bonded together due to hot melting, and do not adhere to the thermosetting part, so as to realize the hot transfer printing of the hot stamping film. The hot stamping can be carried out with an ordinary plastic sealing machine) → hot stamping finished products. Adding special photosensitive color paste, lpr-808 can also be matched into color hot stamping ink

v. UV screen printing elastic varnish, UV brush 2 The liquid medium in the low-temperature tank 1 generally uses alcohol or freezing liquid elastic varnish and UV expansion ink in the printing of simulated oil paintings

UV silk screen elastic varnish uv-105n

uv-105n silk screen elastic varnish is specially used to print all kinds of soft and elastic tomb materials, such as artificial leather, leather, nylon cloth, PVC and other plastic films, and to produce sports shoes, leather bags, etc. In the process of stretching or washing, the cured film expands and contracts synchronously with the substrate, and the cured film has excellent tensile and abrasion resistance. The cured film has excellent toughness and adhesion fastness, high gloss and excellent wear resistance. UV rapid curing, excellent transparency of the cured film, no turbidity, no yellowing

uv pen elastic varnish uv-105nx

uv-105nx pen elastic varnish is colorless, transparent paste, and has obvious thixotropy. After UV irradiation, the cured film is elastic and can withstand tension effects such as stretching and bending. It is used for manual oiling or silk printing on the surface of oil painting, which not only increases the stereoscopic feeling of the picture and makes it more realistic, but also ensures that the curing film will not break or fall off during the stretching and use of the canvas. It is suitable for painting various soft and elastic substrates, such as canvas, artificial leather, leather, nylon cloth, PVC and other plastic films, and producing sports shoes, leather bags and so on. UV rapid curing, excellent transparency of the cured film, no turbidity, no yellowing

light fixation speed: 5~10 meters/minute wire mesh: 20~420 or brush

uv expansion ink uv-850

uv-850 light solid expansion ink, UV curing rapidly, after curing, the film volume expands by 5-10 times, and silk is printed on various paper, leather, clothing, plastic film, gold and silver cardboard and other substrates. It has various colors, and can also be added with gold and silver powder. It has bright colors, strong concave convex feeling and excellent fastness. Compared with ordinary foaming pulp, uv-850 has low expansion temperature, especially suitable for materials with poor heat resistance. It is an ideal product to replace ordinary foaming pulp

the best number of silk meshes is 80~120 mesh. After silk screen printing, it can be dried naturally for a few minutes, and then UV curing foaming can be achieved. The curing speed is 4~8 M/min. (80kW/cm high pressure mercury lamp), the light fixation time is too short, and there may be no expansion effect, otherwise the bubble will break

VI. application of thermosetting anti sandblasting ink, self drying anti sandblasting ink and photosensitive anti sandblasting ink in glass/metal crafts

thermosetting anti sandblasting ink sr-sb-6bl

sr-sb-60bl thermosetting anti sandblasting ink adopts silk printing, which is solvent-free, odorless and non blocking. After the ink is dry, the film has excellent elasticity and toughness, which can withstand the strong impact of sandblasting. It has good adhesion fastness to glass, ceramics and mirror metal. After sandblasting, the film can be easily torn off without residue

precautions: the anti sandblasting ink has high viscosity, so the speed should not be too fast during screen printing. The ink does not contain volatile solvents, and there is no need to add diluents during printing. The thickness of the ink after drying determines the strength of the anti sandblasting ability. The number of wire mesh is 80~150. The mesh is too high, the ink layer is thin, and the anti sandblasting ability is reduced. The thicker the ink layer is, the stronger the anti sandblasting ability is, but the resolution of the silk screen graphics is reduced. After the ink is sandblasted, the cured film can be directly torn off by hand

self drying anti sandblasting ink sb-6bl

sb-60bl is a volatile dry anti sandblasting ink. It adopts silk printing with high graphic resolution. After the ink is dried, the film has excellent elasticity and toughness, which can withstand the strong impact of sandblasting. The ink has good adhesion fastness to glass, ceramics and mirror metal. After sandblasting, the film can be easily torn off without residue

precautions: the viscosity of anti sandblasting ink is large, and the speed of silk screen printing should not be too fast. In order to ensure that the film has a certain thickness after the ink is dried, thinner should be added to the ink as little as possible. The thickness of the ink after drying determines the strength of the anti sandblasting ability. The number of wire mesh is preferably 60~100. The mesh is too high, the ink layer is thin, and the anti sandblasting ability is reduced. The thicker the ink layer is, the stronger the anti sandblasting ability is, but the resolution of the silk screen graphics is reduced. After sandblasting, wash the ink with tap water, and then tear it off by hand

liquid photosensitive anti sandblasting ink lpr-860

lpr-860 is mainly used for the production of fine sandblasting patterns of bright substrates such as glass, wood, mirror metal, marble, ceramics, etc. The photosensitive film has excellent elasticity and impact resistance after curing. High resolution, up to 100 lines. When in use, it can be carried out by means of silk printing, spraying, etc., without making plate patterns. It is especially suitable for the production of small batch, multi variety and fine sand blasting patterns
