SIR INDUSTRIALE was founded in 1956 in Macherio, a small town north-east of Milan, as S.I.R (Società Italiana Resine) in the facilities of former-Bakelite Italia by Italian business-man Angelo Rovelli. The company immediately emerged as one of the Italian leading chemical manufactures. Its early years were characterized by competition with another giant of Italian chemical industry, government-owned Montedison group which, in late ‘80s (1988) acquired S.I.R. that was integrated in the group. After the early ‘90s political changes in Italian government. Montedison Group suffered a financial crisis that led to the acquisition of S.I.R. by P & R Holding (Pizzocaro & Rossi families) in 1996. In 1998 SIR Industriale acquired Sprea Chemicals (a manufacturer of epoxy resins), based in Castelseprio incrementing the production capacity and acquiring the know-how of Taffy process for synthesis of epoxies.
The following years were characterized by focusing on strengthening the company presence in the market, in fact in 2013 SIR went global by reaching an important and symbolic goal exporting more than 60% of its production worldwide.
