Patent ID: 8124710

Claim:
A siloxane resin comprising the units: (i) (R 1 3 SiO 1/2 ) a (ii) (R 2 2 SiO 2/2 ) b (iii) (R 3 SiO 3/2 ) c , and (iv) (SiO 4/2 ) d wherein R 1 , R 2 , and R 3 are independently an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, a has a value 0.05 to 0.5, b has a value of zero to 0.3, c has a value of 0.05 to 0.65, d has a value of 0.05 to 0.6, the value of a+b+c+d=1, and the siloxane resin has a weight average molecular weight of 26,900 to 25,300,000 and with the proviso that greater than 40 mole % of the R 3 groups in the siloxane resin are propyl.
