Please ask ... BASF products can easily be identified and compared within the portfolio. While the brand name relates to the chemistry and performance level, the nomenclature indicates the application and the position on the BASF color wheel. This results in a uniform structure of product codes.
The BASF Color Wheel
The BASF color wheel is divided into ten sectors with consecutive numbers from 0 to 9, each representing a specific color space. The three to four digit numbers in the trade name indicate a position on the color wheel. These numbers are derived from colorimetric data of the product in white reduction at 1/3 International Standard Depth (ISD) and indicate differences in hue between pigments according to the visual impression they make.

Don’t see what you’re looking for? Please ask ... As a world leader in the global chemical industry, BASF offers a wide array of high performance additives that support a broad spectrum of applications across many different industry sectors. These unique raw materials help enable performance driven products meet the latest and most stringent application requirements. Our portfolio comprises a broad technology base of dispersing agents, defoamers, wetting & flow control agents, rheology modifiers, film formation agents, UV absorbers and hindered amine light stabilizers, in-can stabilizers and antioxidants. Dispersing agents wet and stabilize pigments and other particles within formulations. They represent an essential component as they provide color strength, gloss, viscosity stability and prevent sedimentation of particles. Defoamers focus on establishing a perfect balance between excellent foam suppression, high compatibility, long term efficiency and easy handling.
Wetting and flow control agents provide adequate wetting properties, enhance component compatibility and surface flow. Slip and rub control agents provide a formulation with strong slip and surface smoothness effects. Rheology modifiers make it possible to adjust the flow behavior of formulations. Film-forming agents support the film-forming process of an ink. UV absorbers, which can easily be incorporated into the ink formula, provide excellent performance and photostability by filtering harmful UV light and protecting the underlying image against fading. Hindered amine light stabilizers in the formulation are effective in retaining surface properties such as gloss and prevent cracking and chalking. The addition of an in-can stabilizer and antioxidants in the formulation provides long term thermal stability of the energy curable formula during its life cycle.

Oligomers & Reactive Diluents Products at a glance • Laromer® Oligomers • Laromer Reactive Diluents Don’t see what you’re looking for? Please ask ...
epoxy acrylate (EA) oligomers for hardness and reactivity; polyester acrylates (PE) for all around physical properties; urethane acrylates (UA) for flexibility, abrasion and exterior durability; polyether acrylates (PO) for viscosity; water-based acrylates (W) for viscosity, flexibility and hardness.
Laromer® reactive diluents Introduction
Depending on end-use requirements, specific formulations will vary greatly. For UV curable systems, the majority of formulations will contain one or more of the following components: oligomers, monomers, pigments and other additives, and photoinitiators. Oligomers and monomers with acrylate functions are the most commonly utilized components in UV curing due to their high reactivity to initiate radical polymerization. The modification of these building blocks by the introduction of one, two and up to six acrylate groups can be varied depending on the desired properties of the resulting formula. BASF offers a broad portfolio of high quality, high functionality oligomers and monomers for a wide range of formulation requirements. Laromer® acrylate oligomers influence the physical properties of an application whereas the monomers dilute the acrylate oligomers to required formulation viscosities. This variety of oligomer and monomer types provides UV curing formulators with a wide range of possibilities.
Laromer® oligomers
Oligomers are moderately low molecular weight polymers that determine the most basic properties (flexibility, hardness, gloss, adhesion, etc.) of any coating, ink, adhesive, or binder crosslinked by UV curing. Within each Laromer oligomer functional group exists a variety of structural variations to modify physical properties:
Monomers, primarily used as diluents for the acrylate oligomer to achieve viscosities suitable for typical application equipment, can be monofunctional or multi-functional. Like oligomers, monomers within each functional group exhibit a considerable range of performance characteristics: mono-functional monomers contain one reactive group and extend flexibility, slow cure speed and lower hardness; multifunctional monomers contain two or more reactive groups and impart a multitude of desired performances

Photoinitiators Products at a glance • Irgacure® Photoinitiators Don’t see what you’re looking for? Please ask ... A photoinitiator is a compound that undergoes a photoreaction on absorption of light, producing a reactive species. These are capable of initiating or catalyzing chemical reactions that result in significant changes in the solubility and physical properties of suitable formulations. Therefore, the photoinitiator is a compound that can transform the physical energy of light into suitable chemical energy in the form of reactive intermediates. These changes are most commonly achieved by polymerization or polycondensation reactions. Set off by a photoinitiator and light, this process, or energy curing, transforms a soluble liquid formulation into a hard and insoluble crosslinked polymer network. The cured formulation is chemically and physically resistant and protects substrates such as plastics, wood, and metal.
UV cured inks
UV cured inks require fast cure speeds. Generally, these inks are highly pigmented and have a tightly controlled viscosity. To meet these requirements, BASF offers several alpha amino ketone (AAK) photoinitiators. These photoinitiators are very effective in curing dark color inks and can be used alone or in combination with other photoinitiators. Pastel color inks present an additional requirement of color stability. To address this challenge, BASF offers blends of acyl phosphine oxide (APO), AAK and alpha hydroxy ketone (AHK). Generally, a ladder study with a photoinitiator concentration of 1 – 5% is suggested to optimize reactivity. The correct concentration of photoinitiator for optimum performance should be determined in trials. For white, pastel and other
light colored inks, a bis-acyl phosphine oxide (BAPO) photoinitiator is suggested. Activated by a longer wavelength UV light in the near visible region above 400 nm, BAPO photoinitiators show high reactivity in combination with efficient photobleaching.
