Claim 1
Independent Claim
85 words
A COMPOSITION OF MATTER SUITABLE FOR USE AS A COLD-SETTING ADHESIVE OBTAINED BY ADDING 5% TO 25% OF TRIETHYLAMINE TO A FLUID MIXTURE COMPRISING GLYCIDYL ETHER OF A DIHYDRIC PHENOL HAVING A 1,2-EPOXY EQUIVALENCY GREATER THAN 1.0 WHICH ETHER IS OBTAINED BY REACTING ONE MOL OF THE DIHYDRIC PHENOL WITH AT LEAST ONE MOL OF EPICHLORHYDRIN IN THE PRESENCE OF AT LEAST A STOICHIOMETRIC QUANTITY OF AN INORGANIC BASE, SAID COMPOSITION HAVING A VISCOSITY AT 20* C. WHEN FIRST COMPOUNDED OF 1,000 TO 50,000 CENTIPOISES.

Claim 3
Dependent Claim
78 words
A METHOD OF UNITING TWO SOLID SURFACEFS WHICH COMPRISES EFFECTING THE FOLLOWING SERIES OF STEPS AT A TEMPERATURE OF 15* C. TO 40* C. WITHOUT HEATING: APPLYING A COATING OF THE COMPOSITION DEFINED BY CLAIM 1 WHILE IT IS STILL FLUID TO AT LEAST ONE OF THE SURFACES, BRINGING THE SECOND SURFACE INTO CONTACT WITH THE FIRST COATED SURFACE WHILE THE APPLIED ADHESIVE REMAINS FLUID, AND MAINTAINING THE CONTACT AT LEAST UNTIL THE ADHESIVE HAS SOLIDIFIED AND HARDENED.
