BellPearl® Series are non-toxic, high performance phenolic resins with perfectly spherical shape. They are part of KOWA’s Microsphere series which is characterized with high molecular weight and low cross-linking density. PROPERTIES S type: A hot melt, self curing type. Soluble in solvents. Used as binder resins for moldings. Also used as thermo-setting resin. R type: Does not […]
Low-odor and low-metallic glycol ether using proprietary purification technologies. Glycol ethers are mainly used as solvents in paint, ink, detergent and electronic material. Aromatic, aliphatic and ester-type glycol ethers are also used as raw materials in polymers such as acrylic and polyester.
HEMA is an ester of methacrylic acid, soluble in water and has relatively low volatility. It copolymerizes easily with a variety of monomers, incorporates cross-link sites, imparts corrosion, fogging and abrasion resistance, and the hydroxyl group improves adhesion. It is also a key raw material for acrylic polyols.
