Kabasph Additive Solutions For UV Curing Adhesive Sealants

UV 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.

Dispersants

l KBS-F5030 is an acid-containing copolymer solution dispersant. It provides inorganic filler wetting and viscosity reduction, making it suitable for UV-curable systems where fillers such as silica, calcium carbonate, or talc are used to control rheology, hardness, or cost

l KBS-F111K is an acid polyester compound dispersant. It delivers inorganic filler wetting and efficient viscosity reduction, helping formulators achieve stable, processable UV-curable systems with high filler loading.

l KBS-F8500 is a block copolymer dispersant designed for UV curing systems. It provides organic pigment dispersion with viscosity reduction and colour stability, making it suitable for high-quality UV-curable inks and coatings where consistent colour and low viscosity are required.

l KBS-F8600 is an acid polyester compound dispersant. It delivers inorganic filler wetting for efficient viscosity reduction and excellent stability, making it suitable for highly filled UV-curable systems where filler dispersion and long-term storage stability are critical.

Anti-sinking Thixotropic Agents

l KBS-C410K is an organic polyurea anti-sinking thixotropic agent. It has low impact on transparency, viscosity, storage stability, and curing activity, while providing excellent anti-sinking and thixotropic effects. It is suitable for UV curing systems requiring reliable rheology control without compromising optical clarity or cure speed.

l KBS-C6200 is a modified polyamide solution anti-sinking thixotropic agent. It improves thixotropy for acrylic systems by combining with hydrophilic aerosilicones, helping to prevent settling and sagging while maintaining processing and application properties in UV-curable formulations.

l KBS-C7100 is an acid group copolymer solution anti-sinking thixotropic agent. It provides wetting and dispersing for inorganic fillers and effectively prevents the system from sinking. It is particularly useful in UV-curable formulations with dense inorganic fillers where both dispersion and anti-settling performance are required.

Wetting and Levelling Agents

l KBS-L333K is a polyether-modified silicone wetting and levelling agent. It provides excellent wetting and levelling properties and is suitable for a broad range of UV-curable coatings, inks, and adhesives.

l KBS-L331K is a polyether-modified silicone wetting and levelling agent. It delivers excellent wetting and levelling performance combined with foam inhibition, making it useful in UV-curable systems where surface quality and foam control must be addressed together.

l KBS-L3580A is a polyacrylate solution levelling agent with good compatibility. It is suitable for improving the levelling of highly transparent systems, especially clear UV-curable coatings and transparent sealants where optical clarity is critical.

l KBS-L411K is an organosiloxane polymer wetting agent designed for oily substrates. It strongly reduces surface tension and effectively solves the loss of adhesion caused by substrate oil contamination. It is recommended for UV-curable applications where substrate cleanliness cannot be fully guaranteed.

Defoamers

l KBS-X052K is a polyacrylate non-silicone defoamer. It offers good compatibility and efficient defoaming performance, making it suitable for UV-curable systems where silicone-free foam control is preferred.

l KBS-X053K is a non-silicone defoamer with better effect on PU systems. It provides reliable foam control and is suitable for UV-curable formulations where compatibility with polyurethane-modified systems is required.

l KBS-X055K is a polyacrylate non-silicone defoamer. It delivers good compatibility and efficient defoaming performance, making it suitable for a broad range of UV-curable coatings, inks, and adhesives.

Tackifiers

l KBS-T0100 is an amino-containing organosilane tackifier. It provides excellent adhesion to metallic and non-metallic surfaces, making it suitable for UV-curable adhesives, sealants, and coatings where durable bonding to diverse substrates is required.

l KBS-T0200 is an epoxy-containing organosilane tackifier designed for UV curing systems. It is intended to improve adhesion to metal and non-metal substrates. Detailed technical characteristics are available upon request.

l KBS-T0300A is a polyester compound tackifier. It provides excellent adhesion to metal surfaces with modified flexibility, helping improve bonding performance in UV-curable systems where both adhesion and flexibility are required.

Application Areas

UV curing systems are widely used in applications requiring rapid curing, high productivity, excellent surface properties, and environmental compliance. Typical application areas include:

l UV-Curable Coatings — Clear and pigmented coatings for wood, plastic, metal, glass, and concrete surfaces. These systems require good pigment and filler dispersion, anti-settling, levelling, and foam control without affecting cure speed.

l UV-Curable Inks — Flexographic, gravure, screen, offset, and inkjet inks. Organic pigment dispersion, colour stability, and efficient defoaming are essential for consistent print quality and fast curing.

l UV-Curable Adhesives and Sealants — Pressure-sensitive adhesives, laminating adhesives, structural adhesives, and sealants for electronics, automotive, medical, and general industrial applications. Additives help improve filler dispersion, rheology control, substrate wetting, and adhesion.

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.

l Optical and Transparent Systems — UV-curable clear coats, optical adhesives, and transparent sealants where compatibility, levelling, and colour stability are essential. KBS-L3580A and KBS-F8500 are particularly suitable for such applications.
