MOLTEN ADHESIVE Russian patent published in 1995 - IPC

FIELD: molten adhesives used for bonding metal surfaces (for fixing coils of TV deflecting systems). SUBSTANCE: the invention makes it possible to improve adhesion strength of enamel coated metal surfaces to 6.8 MPa, to impart self-attenuation, while retaining stability to cyclic temperatures loads and higher moisture content due to using polyether based on dimethyl terephthalate, dimethyl orthophthalate, dimethyl isophthalate, ethylene glycol and diethylene glycol, a plasticizer and a filter. The TF-30 polyester comprises (wt %): 51-55 dimethyl terephthalate; 22-24 ethylene glycol; 23-25 diethylene glycol. The copolyester comprises (wt %): 38-40 dimethyl terephthalate; 5.5-5.7 dimethyl orthophthalate; 7-11 dimethyl isophthalate; 40-42 ethylene glycol; 3.3-5.5 diethylene glycol. EFFECT: improved properties of the molten adhesive. 2 tbl
