pigment

Pigments are required to possess various properties such as lightfastness, weather resistance, heat resistance, water resistance, and solvent resistance, and also need to have high opacity.
Organic pigments include azo pigments, which are produced by diazotizing aromatic amines and reacting them with various coupling components, as well as phthalocyanine pigments and high-grade organic pigments, which are synthesized from phthalic anhydride, urea, and copper chloride and possess excellent performance characteristics.
In addition, we handle a wide range of inorganic pigments, including composite oxide pigments, and processed pigments such as acrylic copolymer colored beads and processed pigments for oil-based and water-based paints.

• Pigments: Soluble azo pigments, insoluble azo pigments, phthalocyanine pigments, high-grade pigments, etc.

• Inorganic pigments, composite oxide pigments, such as Prussian blue.

• Processed pigments, acrylic resin beads, common color bases for paints, etc.

Synthetic silica

Synthetic silica used in synthetic rubber for large truck and bus tires and footwear exhibits excellent reinforcing effects, such as good durability, high hardness, and wear resistance, due to its extremely high surface reactivity.
It is particularly ideal for light-colored and transparent rubber products. Furthermore, uniform, ultrafine silica particles are widely used in the paint industry.
It is particularly excellent for creating a matte finish on audio equipment and high-end furniture. It is also widely used in specialty papers, defoamers, fluidity modifiers, and pesticides.

• For rubber applications, it offers high reinforcing properties and allows for transparent and light-colored formulations.

• For agricultural applications, it exhibits high oil absorption capacity due to its large pore volume.

It has a sharp particle size distribution and exhibits good dispersibility.

Hydrophobic silica has water-repellent properties and excellent water resistance and moisture resistance.

Due to its high specific surface area and high liquid absorption capacity, it is effective in preventing caking and improving the fluidity of food products.

It is amorphous and of high purity, so there is no concern about silicosis or toxicity.

炭酸カルシウム

<Product overview>

Due to its low cost, relatively low specific gravity, and excellent dispersibility, fluidity, thermal stability, and weather resistance, it is widely used as an industrial filler in paints, printing inks, various plastics, various rubbers, sealants, papermaking, adhesives, and pharmaceuticals for purposes such as extender pigments, volume increase, stability improvement, and reinforcement.

<Features>
• It has excellent processability, including dispersibility and fluidity.
• It has good thermal stability and weather resistance.
• It is hydrophobic and does not absorb moisture.
It is suitable for improving functions such as impact resistance, tensile strength, tear resistance, and rigidity.
• Edge resistance is good.

<Application>
Paints: Synthetic resin paints, water-based paints, oil-based paints, traffic paints, sealants, caulking materials, putties; Plastics: For extruded products, injection molded products, calendered products, blow molded products, and vacuum formed products; Rubber: Synthetic rubber, natural rubber, latex; Adhesives; Papermaking; Fertilizers; Building materials; Glass; Pharmaceuticals; Food additives; Cosmetics, etc.

Raw materials for polyurethane

Polyurethane resins are synthesized by reacting a glycol-based polyol with diisocyanates, which are primarily bifunctional isocyanates, and various combinations are used depending on the application.
Polyurethane resins have excellent elasticity, weather resistance, abrasion resistance, chemical resistance, solvent resistance, stain resistance, and electrical properties, as well as high adhesion, making them widely used in water-soluble paints, hot-melt adhesives, urethane foams, automotive parts, synthetic leather, textile products, and more.
Our company specializes in polyols and polyisocyanates for use in paints and adhesives.

• Polyether polyol

Polyester polyol

We also stock a variety of other polyols.

• Aromatic polyisocyanates

• Aliphatic polyisocyanates

• Block-type polyisocyanates

We also stock various other types of isocyanates.

DBU/DBN

We handle the U-CAT series and POLYCAT series, which are modified versions of DBU (diazabicycloundecene), DBN (diazabicyclononene), and resins to improve compatibility with these materials.
