Claim 12:
13. The composition of claim 1, wherein the composition is characterized by a shear storage modulus G′ and a shear loss modulus G″, wherein,
the initial G″/G′ ratio is less than 2;
the initial G′ is greater than 1,500;
the G′ at 6 minutes is greater than 500,000 Pa; and
the G″ at 6 minutes is greater than 400,000 Pa; wherein,
the initial G″/G′ ratio and the initial G′ refer to values measured within 30 seconds after the first component and the second component are mixed;
the G′ and G″ after 6 minutes refers to the values measured 6 minutes after the first component and the second component are mixed; and
the shear storage modulus G′ and the shear loss modulus G″ are measured using a rheometer with a gap from 1 mm to 2 mm, with a 25 mm-diameter parallel plate spindle, an oscillation frequency of 1 Hz and amplitude of 0.3%, and with a rheometer plate temperature of 25° C.
