Features

Features of ARONIX

ARONIX is the brand name of acrylic monomer and oligomer products. We offer a broad range of acrylic monomers, including monofunctional acrylates, which are effective for improving ease of handling and adhesion, bifunctional acrylates, which are effective for adjusting curability and improving film strength, and multifunctional acrylates, which possess high coating film hardness and curability and are widely used for hard coats, inks, color resists, and other applications. Acrylic oligomers are designed to offer the properties needed for different applications. Among these, polyester acrylate has been widely used for painting and coating since Toagosei became the first to succeed in their mass-production in Japan. We also offer many other products, including urethane acrylate and epoxy acrylate, in addition to those featured in the catalog. Furthermore, we have also developed the ARONIX UV Series, founded on our own blending and evaluation technologies, which have an established track record in many products such as adhesives and coatings. Feel free to contact us regarding your concerns for blending products.

  1. 1.Eco-friendly products (solvent free)

    Water-based inks and paints (emulsions and aqueous types) have been rapidly replaced by solvent free types (powdered paints, UV-curable resins) in response to solvent regulations (Pollutant Release and Transfer Register) and to improve the workplace environment (in terms of odor and flammability). UV-curable resins can be made entirely solvent free.
    Depending on the application, a high-solid system (high solid content) with a small amount of organic solvent or water-soluble UV-curable resins may also be selected.

  2. 2.Energy saving and increased production speed

    Generally, UV-curable resins can be cured instantaneously by exposure to UV light. This feature eliminates the drying time normally required for heat-dried paints, which can be solvent or water based, and for systems cured by crosslinking of melamine, epoxy, or urethane groups. As the need for a drying oven is eliminated, this system contributes energy conservation and increased productivity (enhanced line speed), as well as enables the compactness of manufacturing facilities.
    In addition, ARONIX can be used on materials that are not heat resistant.

  3. 3.Wide range of product designs

    The physical properties of cured products can be designed by altering the reactive groups contained in a resin molecule or modifying the resin type and skeletal structure. If a resin has multiple reactive groups in one molecule, a highly cross-linked structure can be obtained in the cured product.
    This cross-linked structure increases the hardness, heat resistance or chemical resistance of the resulting coated film. Conversely, the crosslinking density can be decreased by blending in resin with one reactive group per resin molecule, to give rise to a flexible coated film. Since the reaction only takes place in areas exposed to light, it is possible to control the reaction through masking or similar means to allow only the required parts to react.

Usage

Use as UV-curable materials

UV-curable resins undergo polymerization as the initiator produces radicals and cations with exposure to light. Given the advantage of this reaction, UV-curable resins are used in a wide range of fields. Generally, the use of UV-curable resins can minimize the amount of solvent use, thereby making it possible to design products that are earth and work environment friendly. There are also other advantages as follows.

  1. 1.Rapid curing time

    The short curing time enhances production and energy efficiency (energy saving), reduces space, and makes it possible for use on non-heat resistant materials.

  2. 2.Easily controlled curing process

    Since the reaction only takes place in areas exposed to light, it is possible to control the reaction through masking or similar means to allow only the required parts to react.

Light-curable inks and paints

Light (ultraviolet light) curable inks, characterized by their high curing speed, have been in practical use since around 1970 for sheet-fed printing and off-wheel printing. Lately, their applications have expanded to gravure inks and inkjet inks. They are indispensable as materials for a range of resist inks that take advantage of their image forming properties. Light (ultraviolet light) curable paints are widely used as protective coatings and hard coatings for paper, wood, plastics, and metals, and in everyday products, including beverage cans, fiber optic materials, and mobile phones.

Electron beam curable paints

Radical polymerization is a method of curing the coating surface using an electron beam. As it does not involve the use of light initiators, they can be used for materials impenetrable to light including metallic films and high-concentration pigments. While this method also increases adhesiveness, they are subject to severe equipment limitations and have yet to find widespread application.

Light-curable adhesives

As with other adhesives, light-curable adhesives exert their adhesive functions by forming polymers and hardening through polymerization reactions. They are characterized by the chain polymerization reactions triggered by irradiation with light. Moreover, they require no mixing of two solutions, offer flexibility in set time, as well as possess excellent storage stability. Their use in the field of data recording media, such as DVDs, has become more in demand in recent years.

Resist materials

These are used in both etching and solder resists. Materials that contain carboxylic acids are used to produce alkaline developing ability. The use of resist materials in LCD color filters has increased in recent years. They are also used in press plates for flexographic printing, such as for newspaper printing.

Epoxy resin modification

Amine curable epoxy resin modification

The reaction between the acryloyl group and polyamine as a curing agent is known as Michael addition. The low-temperature curing performance, filler compatibility, and adhesiveness of an amine cured epoxy resin can be enhanced with the addition of a small amount (generally around 5%) of ARONIX.

Plastic cross-linker, modification agent

Owing to its high reactivity, AORNIX can be used as a cross-linking additive to various plastic materials, such as synthetic rubber and polyvinyl chloride, pastes, and emulsions to improve the physical properties (such as hardness, strength, heat resistance, weatherability, and chemical resistance) and adhesiveness of the materials. Moreover, ARONIX may be added in small quantities, normally 5% or less, to modified silicone sealant or polyurethane sealant to add special features, such as surface drying properties and increased weatherability.

Specifications

ARONIX curing methods

The curing methods of ARONIX can be roughly categorized into two types: radical polymerization reaction of acrylic unsaturated bond (shown in [1]) and addition reaction of active hydrogen (for example, active amine hydrogen) to acrylic unsaturated bond (shown in [2]).

Typical methods of curing ARONIX are as follows.

Curing methods Example of catalyst system
Radical polymerization Heat-curing
Thermal oven, far infrared, microwave
Add benzoyl peroxide, dicumyl peroxide, etc. as the catalyst (radical initiator).
Redox-based room temperature curing Add benzoyl peroxide, dimethylaniline, cumene hydroperoxide, vanadium-based accelerator, etc.
Anaerobic curing Add hydroperoxide, tertiary amine, sulfimide, etc.
UV-curing Add a photoinitiator (such as benzoyl alkyl ether, benzophenone, or acetophenone)
Electron beam curing (no catalyst added)
Michael addition Room temperature, heat-curing Add a polyamine possessing a primary or secondary amino group.

Exposure of ARONIX, special acrylic monomer and oligomer product, to the skin, eyes, or mucous membranes may trigger rashes, inflammation, and allergic reactions.

  1. 1.Ensure proper ventilation

    Generally, it has a high boiling point and low volatility, therefore there is almost no damage to the skin caused by steam at room temperature. However, steam may occur during heating or UV-curing. Ensure proper ventilation in the work space.

  2. 2.Wear appropriate protective equipment
    1. 1.Wear protective equipment such as gloves, apron, and safety goggles to avoid contact of the substance with the skin, and do not handle with bare hands.
    2. 2.If wearing protective gloves, make sure the contaminated gloves do not touch the skin.
    3. 3.Natural rubber is an effective material for the protective gloves. Vinyl gloves may allow the material to penetrate and are not suitable.
  3. 3.Promptly rinse under water if the product comes in contact with the skin.

    Be very careful of skin contact as the liquid is clear and does not cause irritation when initially exposed to the skin.
    Rinse with soap water immediately as long term contact with skin can cause skin damage.
    Avoid washing with solvents, as they will speed up penetration of the material into the skin.
    In case of skin contact, inhalation or ingestion of the material, seek medical attention and treatment even without subjective symptoms.

  4. 4.If the product gets in contact with the eyes, immediately rinse with plenty of water for at least 15 minutes and seek medical attention from an ophthalmologist.
  5. 5.If inhaled, relocate to a place with fresh air to rest and seek medical attention immediately.
  6. 6.Seek medical attention immediately if ingested.
    • *This is an inflammable and flammable substance. Keep away from heat, sparks, open flames and other sources of ignition. In the event of a fire, wear protective equipment (and a respirator if necessary) to extinguish the fire from upwind using powder, foam or carbon dioxide fire extinguisher.
    • *As a highly reactive substance, polymerization will occur as a result of exposure to light, impact, heat, and mixing with other substances, which can lead to sudden heating, damage and breakage of containers. Use upon confirming the reactivity in advance.
    • *In case of a spill from the container, remove sources of heat and ignition from its surrounding, and use paper towel or sand and gravel to recover the spillage in an empty container if the amount is small, then rinse the area with plenty of water. If there is a large amount of spill, enclose it in embankment to stop the outflow and collect it in a closed container. Handle while wearing protective equipment.
    • *Contact a waste material processor for disposal.
