QualiCure GM Series Monomers

Reactive diluents for UV curable formulations: mono-, di- and multi-functional acrylates and methacrylates. They adjust viscosity, curing speed and crosslink density of the film. The catalogue lists IBOA, THFA, 2-PEA, CTFA, TPGDA, HDDA, DPGDA, TMPTA and Di-TMPTA plus a toluene-free TF range.

Mono-functional: IBOA, THFA, IDA, 2-PEA
Toluene-free: TPGDA-TF, HDDA-TF
Tetraacrylate: Di-TMPTA

QualiCure GU Series Oligomers

Film-forming backbone of UV curable formulations: bisphenol A and novolac epoxy acrylates, aliphatic and aromatic urethane acrylates, polyester acrylates, amine modified polyether acrylates and waterborne urethane acrylates. The oligomer sets hardness, flexibility, adhesion and chemical resistance.

GC Amine Synergists and Photoinitiators

Reactive amine synergists of the GC series work together with photoinitiators: they raise free-radical generation and speed up surface cure. Photoinitiators in the catalogue include TPO, ITX, benzil dimethyl ketal, benzophenone and methyl-o-benzoylbenzoate, mostly crystalline powders.

QualiCure GA Series UV Additives

Functional additives for UV curable formulations that raise process stability, curing efficiency and film surface quality. The catalogue lists an acidic methacrylate adhesion promoter for metal and glass, modified polyester acrylates for pigment dispersion and a silicone acrylate for surface slip.

Silicone acrylate: surface slip
Dispersion and oil-water balance

GP OPV and 3D Printing, GE Electronic Resins

The GP series covers transparent UV overprint varnishes (OPV) for printed materials and resins for UV 3D printing. The GE series serves PCB solder masks and electronic encapsulation. Modified urethane acrylates for adhesives and 3D printing come clear or pigmented.

OPV: gloss and surface protection
UV 3D printing: precision parts
GE resins: PCB solder masks
White solder mask: since 2014

Unsaturated Polyester, Vinyl Ester and Flame Retardant Resins

Thermosetting resins for FRP. Unsaturated polyesters cure at ambient temperature with initiators, vinyl esters combine the corrosion resistance of epoxies with polyester processability, flame retardant grades reduce flammability. Uses: tanks, corrosion-resistant equipment, building materials.

Cure: ambient temperature
Vinyl ester: chemical tanks
Flame retardant: FRP building parts
Low emission polyester: since 1983

Alkyd, Polyester, Acrylic and Amino Resins

Binders for paints and coatings: super long to short oil alkyds, saturated oil-free and silicone modified polyesters, thermoplastic and thermosetting acrylic resins, acrylic polyols for two-pack polyurethane systems, and butylated melamine and urea formaldehyde resins.

Alkyds: super long to short oil
Acrylic polyol for 2K polyurethane
Amino resins: butylated
Acrylic resins: automotive refinish

Low-Dielectric Resins, PSMA and Electronic Crosslinkers

Low Dk and Df resins for high-frequency 5G PCBs and servers, styrene maleic anhydride copolymer (PSMA) with reactive anhydride groups, electronic crosslinkers for thermal resistance, and electrical materials for encapsulation and potting of components.

5G substrate resins: mass production 2023
PSMA: mass production since 2021
Crosslinkers: react with amines and hydroxyls
Wire and cable insulation

Oligomer and Monomer in a UV Formulation

The film is defined by the GU oligomer: epoxy acrylates give heat resistance and hardness, aliphatic urethane acrylates give weatherability for outdoor coatings, polyester acrylates give pigment dispersion in litho and flexo inks.

The GM monomer is chosen for viscosity and substrate: mono-functional acrylates raise adhesion to plastics and metals and lower shrinkage, di- and triacrylates speed up crosslinking.

Some oligomers come already diluted in monomer, for example a urethane diacrylate in 25% IBOA or an epoxy diacrylate in 20% TPGDA: the monomer share is counted in the formulation balance.

Cure Speed: Synergist and Photoinitiator

A GC amine synergist is added together with the photoinitiator: it raises free-radical generation and speeds up surface cure, which matters on high-speed UV lines. Synergists work only in free-radical UV systems; besides monomeric amines the catalogue lists an oligomer amine synergist.

Photoinitiators are supplied mostly as crystalline powders and are dissolved in the monomer or oligomer before they go into the formulation. The photoinitiator and synergist grades are matched by TDS to film thickness and pigmentation.

FRP Resin for the Service Medium and Flammability Requirements

Unsaturated polyester resin cures with an initiator at ambient temperature and suits tanks, building materials, transport and marine parts.

For aggressive media a vinyl ester resin is used: its epoxy backbone gives higher chemical and heat resistance, so it goes into chemical tanks and corrosion-resistant equipment.

Where the part has to meet flammability requirements, a flame retardant resin is used for building panels, electrical equipment and transport.

Binder for Lacquers and Enamels

An alkyd is chosen by oil length and oil: long soya alkyds go into white and coloured air-drying ready mixed paints, shorter grades on soya and coconut fatty acids into baking enamels, acid curing and nitrocellulose lacquers.

Butylated melamine and urea formaldehyde resins crosslink the alkyd in acid curing amino-alkyd wood lacquers and in metal baking enamels.

Two-pack polyurethane coatings use an acrylic polyol, oil-free systems a saturated or silicone modified polyester; acrylic resins add weather resistance and transparency.
