The molecules of Sakamoto Yakuhin Kogyo specialty resins contain an active epoxy group that causes them to readily react with compounds having activated hydrogen. They are widely used as modifiers and cross-linking agents for fibers and resins.
     
   1. Low viscosity makes these resins suited for use as reactive diluents for bisphenol A type epoxy resins.
2. Confer flexibility, adhesion, and weather resistance to epoxy resins.
3. Water-soluble epoxy is suited for use as a curing agent for water-based emulsion paints and adhesives.
4. React with thermosetting resins to improve impact resistance.
5. Improve adhesion and impact resistance when used as modifiers of polyester resins and other thermoplastic resins.
6. Used as stabilizers of vinyl chloride type resins.
7. Confer durability and crease-resistance for cotton, synthetic fibers, and blended fabrics.
