Super-Bond™ Dental Adhesive to Launch in Brazil
Three-way business partnership between SHOFU, SUN MEDICAL and Mitsui Chemicals

SHOFU INC. (Tokyo: 7979; President & COO: TAKAMI Tetsuo), SUN MEDICAL CO., LTD. (HeadOffice: Moriyama, Shiga; President & CEO: NAKAJIMA Yoshiyuki) and Mitsui Chemicals, Inc. (Tokyo:4183; President & CEO: HASHIMOTO Osamu) today announced that Shofu Dental Brasil Comerciode Produtos Odontologicos Ltda. (Shofu Brasil; Head Office: Sao Paulo, Brazil; President:
HARASHIMA Tomomi), a sales subsidiary of SHOFU, will launch Brazilian sales of SUN MEDICAL’s
Super-Bond™ dental adhesive in June 2023.
Employing 4-methacryloxyethyl trimellitate anhydride (4-META) as a dispersion-aiding monomer andtributylborane (TBB) as a polymerization initiator, Super-Bond™ is an acrylic resin cement made foruse as a dental adhesive. It is referred to in academic literature as a 4-META/MMA-TBB resin. SUNMEDICAL began producing and selling the product in 1982, and since sales first began in Japan, thematerial has become a favorite among dentists due to its excellent adhesive properties and ample
track record of effectiveness. Super-Bond™ finds use in a wide range of applications, including
stabilizing mobile teeth, forming direct resin-bonded bridges, and enabling the adhesion of brackets
and ceramic prostheses. The material enjoys widespread use in clinical settings around the world,with exports already going out to the U.S., Europe, China and South Korea.

excellent adhesion to tooth material (enamel/dentin), dental alloys and ceramics alike. The product’s
mechanism sees Catalyst V, which has TBB as its main component, react with water and oxygen toserve as a polymerization initiator. Super-Bond™ is especially notable for its adhesion to toothmaterial, which is difficult to keep completely dry: since hardening begins at the adhesive interface,
the product is able to exhibit better adhesive strength and adhesive durability here than conventional
resin cements.

Super-Bond™ recently received pharmaceutical approval in Brazil, where the dentistry market looks setfor growth going forward. This then prompted the decision to begin sales in this market, helping thosein the country to keep their natural teeth for longer. Starting with an exhibition at CIOCE 2023 – aninternational dentistry conference set to be held in Fortaleza over May 6–9, 2023 – efforts will be madeto gradually introduce the product across the country via KOL marketing at seminars and other suchvenues.

Comment from President HARASHIMA Tomomi of Shofu Brasil, which will sell the material:
We are honored to announce the Brazilian launch of Super-Bond™, which has been held in highregard among dentists for some 40 years. Based on its excellent clinical results so far, we believethat sales of the product will aid dental treatment in Brazil, where minimally invasive surgery has
been on the rise.
