Products Description
CQ is an efficient and low-toxic photosensitizer, which is widely used in both medicine and industry. In medicine, it is mainly used to produce dental materials such as dental fillings, enamel repair agents, dental adhesives, etc.
It is one of the common photoinitiators in dental materials and is often used in combination with amine compounds. In addition, it can also be used to manufacture printed circuit boards, sealing insulating components for optical instruments, etc.
It has excellent ultraviolet-visible absorption within the visible light range of 400-500nm, and possesses good light source response capability and light source matching performance.
CQ and common amine type curing initiators such as DMABE, DMABN, and DMAEMA ,The ability to be polymerized and macromerized is also one of the research directions for this type of photoinitiators. After all, minimizing the mobility of the photoinitiator and the by-products of light irradiation to a certain extent also reduces the toxicity of the photo-curing material.

Products Application
1. Dental medical materials: Light-cured dental filling resin, dental adhesives, dental restoration materials (primary application).
2. Light-cured materials: UV coatings, inks, electronic packaging resins, 3D printing photopolymer resins.
CQ is a visible light initiator; Bis-GMACAS 1565-94-2 , UDMACAS 72869-86-4, and TEGDMACAS 109-16-0 are methacrylate monomers, and the four of them together constitute the dental visible light-curing resin formulation PMC.
FAQ
Q: Is DL-CAMPHORQUINONE sensitive to light?
A: It is highly photosensitive. Storage and packaging must be protected from light. Exposure to light will cause the product to decompose and lose its effectiveness.
Q: Can it be used as a sole photoinitiator?
A: Generally, it needs to be combined with amine-type auxiliary initiators to achieve efficient visible light curing.
Q: What is the relationship between CQ and Bis-GMA, UDMA, and TEGDMA?
A: CQ is a visible light initiator; Bis-GMA, UDMA, and TEGDMA are dental resin monomers. CQ is excited by visible light to generate free radicals, which trigger the copolymerization and cross-linking of these three types of monomers, achieving the curing and shaping of the resin.
Q: Why are Bis-GMA, UDMA and TEGDMA included in the dental resin formula?
A: Bis-GMA and UDMA provide strength and toughness after curing, TEGDMA reduces the viscosity of the paste, and CQ initiates the cross-linking of these monomers to form a solid dental material.
Q: Is CQ suitable for water-based photopolymerization systems?
A: It has very poor water solubility and is more suitable for solvent and resin matrix systems, rather than pure water-based formulations.
