<p>1527448 Anaerobically curable compositions LOCTITE CORP 15 June 1977 [ 17 June 1976] 24991/77 Headings C3P and C3V An anaerobically curing composition which is self-emulsifying in water comprises: (1) an anaerobically curable acrylate monomer, (2) a free radical initiator and (3) 0À25 to 10 wt. per cent based on the total composition of one or more anionic and/or nonionic surfactants dissolved in the composition to render it selfemulsifying in water. Suitable acrylates are polyacrylate esters; the use of triethylene glycoldimethacrylate and 1, 3-butylene glycol dimethacrylate mixed with lauryl methacrylate being exemplified. Any nonionic or anionic surfactant may be used, provided that it will dissolve in components (1) and (2). Many examples of ethoxylated and sulphonated materials are given. The compositions may be used to impregnate porous materials and excess composition not absorbed by the pores may be washed off with water owing to the self-emulsifying characteristic of the compositions.</p> |
