UV curable adhesives are one-component materials, they can cure quickly after UV exposure to high-strength materials. But during UV adhesives production, there are issues like curing bad, not enough depth curing, or surface sticky. Then how to make good UV curable adhesives? To make good UV curable adhesives, in other words, is to improve the performance […]
Photopolymerization system, use very little doge of photoinitiator. It is a crucial material. Absorption wavelength, molar extinction coefficient, and photoreactivity have obvious effects on photoinitiation performance. Photoinitiator directly affects the curing speed, yellowing, and cost. After the photoinitiator molecule absorbs light, it mainly generates active species in the excited triplet state through related chemical action and initiates […]
For making sure that the UV ink is completely cured by the UV lamp, there’re four detection methods. The pencil hardness is included in the technical conditions of all UV inks tests. According to this requirement, we can use pencil hardness equipment to test. If it meets the requirements (usually 3-4 hours), it proves that the ink has […]
UV ink is a kind of economical and efficient ink, it has covered all printing fields. UV ink includes UV grinding, UV freezing, UV foaming, UV wrinkling, UV embossing, UV refraction, UV embellishment, UV light fixing, UV varnishing special packaging printing inks. On the glossy printing surface of the metal mirror, the UV ink printing […]
3D printing is a new technology developed in recent decades. Light curing rapid prototyping Stereolithography technology (SLA) is the earliest and most mature technology in 3D printing. Photosensitive resin plays a very important role in 3D printing, it refers to a resin material that can exhibit special functions under the excitation of ultraviolet light. 3D Printing […]
UV photoinitiator is to initiates a radical polymerization reaction. The “photo” in “photopolymerization” means light. Obviously, the initiator is light-activated. In other words, polymerization won’t start until the initiator is exposed to light, specifically UV light. There are two types of initiators, the radical initiator, and the cation initiator. The radical initiator is used more […]
Photocuring technology is excellent material surface treatment technology and processing technology. It is an efficient, environmentally friendly technology. While photoinitiator is a kind of active intermediate, which absorbs radiant energy and undergoes chemical changes upon excitation (free Group, cation, or anion), plays an important role in the photo-curing system. The future direction of photoinitiators focuses […]
Dioctyl phthalate is one of the most important plasticizer, also called DOP, DEHP. It is mainly used in the processing of polyvinyl chloride resins. It can also be used in the processing of polymers such as chemical fiber resins, acetate resins, ABS resins, and rubbers. Lacquer, dyestuff, dispersant, etc. PLASTIC WRAP Plasticizers have lots of […]
For fluorescent and fluorescent whitening agents, people usually misunderstood it. In fact, fluorescent substances are not harmful, and without fluorescence substances are not harmless. Fluorescence is not necessarily related to toxic or non-toxic. People are not afraid of fluorescence, but fluorescent brighteners. When we talk about fluorescence, fireflies in the night always appear in our […]
