2-Isopropylthioxanthone is an efficient Norris II (hydrogen abstraction type) free radical photoinitiatoran additive,widely used in UV curing technology, which can efficiently absorb UV light and promote rapid curing of materials.This ingredient is commonly used in the production of printing inks, coatings and adhesives to improve processing efficiency.
The main product characteristics as below
Long wave strong absorption
It has strong absorption for long wave UVA (~382nm) and can effectively penetrate pigment layers and thicker coatings, promoting deep and uniform curing. In coatings and ink systems containing masking fillers such as titanium dioxide and color pigments, high initiation efficiency can still be maintained.
Potential migration risks
Its molecular weight is relatively small, even after curing, some unreacted or degraded products may still migrate out of the cross-linked network,especially on non-polar substrates. Not recommended in any field that may directly or indirectly come into contact with food, drugs, oral or infant products.
Application
Inks
Suitable for flexographic printing, screen printing inks, especially white or colored inks that require curing depth.
Sports goods surface treatment
The coating is suitable for sports goods such as rackets and helmets to enhance the impact resistance and wear resistance of the surface and maintain a new appearance.
Surface coating on building materials
The protective coating for floor, metal or plastic building materials is UV resistant and corrosion resistant, suitable for indoor and outdoor environments.
Industrial adhesive applications
It plays a role in rapid curing of adhesive, improves bonding strength and efficiency, and is suitable for bonding porous and non-porous materials.

FAQ
Q: What type of uv light is best for 2-ITX?
A: 2-Isopropylthioxanthone has the best absorption effect on long-wave ultraviolet (UVA), so it is especially suitable for curing equipment equipped with UVA light sources such as 365nm or 385nm.
Q: In which daily necessities are they common?
A: It is commonly used in all kinds of printed matter (such as magazines, packaging), furniture surface coating, electronic product shell protective paint and some high strength adhesives.
Q: Can it be used to solidify colored systems?
A:Yes. Long-wave ultraviolet light has a stronger penetration of pigment, so 2-ITX can still perform well when curing some pigment-containing color paint or color ink.
