Kabasph series of additives is specifically developed for UV curing systems and is suitable for applications such as UV-curable coatings, inks, adhesives, 3D printing resins, electronic encapsulation, photoresists, and high-performance industrial systems. The product range covers five major categories—dispersants, anti-sinking thixotropic agents, wetting and levelling agents, defoamers, and tackifiers—providing a comprehensive additive solution for UV-curable formulations. It addresses key challenges including inorganic filler wetting and viscosity reduction, organic pigment dispersion and colour stability, anti-settling and sag control, surface wetting on oily substrates, levelling, foam control, and adhesion to metal and non-metal surfaces, while maintaining compatibility with photoinitiators, curing speed, storage stability, transparency, and final film properties.

KabasphUV curing systems are widely used in coatings, inks, adhesives, 3D printing resins, electronic encapsulation, photoresists, and optical applications where rapid curing, high productivity, and excellent surface properties are essential. However, formulating with these systems presents unique challenges: inorganic filler wetting and viscosity reduction, organic pigment dispersion and colour stability, settling and sagging, wetting on oily or contaminated substrates, levelling, foam generation, and adhesion failure on metal and non-metal surfaces. Additives must be carefully selected to maintain compatibility with photoinitiators and UV-curable resins without adversely affecting curing speed, storage stability, transparency, colour, or final film properties.

l 3D Printing Resins — UV-curable photopolymer resins for stereolithography (SLA), digital light processing (DLP), and other 3D printing technologies. Anti-settling, levelling, and defoaming performance are critical for layer uniformity and print accuracy.
l Electronic Encapsulation and Photoresists — UV-curable systems for encapsulating electronic components, sensors, and LEDs, as well as photoresists for printed circuit boards and semiconductor manufacturing. High filler loadings and transparent systems require efficient dispersion, anti-settling, and defoaming.
