Abstract
Abstract A method is described for providing a protective finish to a vinyl substrate by applying to the vinyl substrate a vinyl protectant composition. In one embodiment the composition is an abrasive free mixture of a film forming polysiloxane; a diluent; and a wax in the form of micronized particles having an average diameter of 3-12 microns. In another embodiment, the composition is a hydrocarbon solvent free mixture of a film forming polysiloxane; water; and an amorphous silica in the form of fumed silica particles having an average diameter of 7-30 nanometers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A method of providing a protective finish to a vinyl substrate comprising applying to the vinyl substrate a vinyl protectant composition which is an abrasive free mixture of 5-60 percent by weight of a film forming polysiloxane which is selected from the group consisting of a polydimethylsiloxane having a viscosity of 100 to 1000 centistokes and having a silanol functional phenyl based silicone resin having present in the resin CH 3 SiO 1 .5, (CH 3 ) 2 SiO, (CH 3 )(C 6 H 5 )SiO, and (C 6 H 5 ) 2 SiO siloxane units; 20-50 percent by weight of a diluent; and 1-20 percent by weight of a wax in the form of micronized particles having an average particle size of 3-12 microns.
Claim 2
Independent Claim
125 words
A method of providing a protective finish to a vinyl substrate comprising applying to the vinyl substrate a vinyl protectant composition which is an abrasive free mixture of 5-60 percent by weight of a film forming polysiloxane which is selected from the group consisting of a polydimethylsiloxane having a viscosity of 100 to 1000 centistokes and having a silanol functional phenyl based silicone resin having present in the resin CH 3 SiO 1 .5, (CH 3 ) 2 SiO, (CH 3 )(C 6 H 5 )SiO, and (C 6 H 5 ) 2 SiO siloxane units; 20-50 percent by weight of a diluent; and 1-20 percent by weight of a wax in the form of micronized particles having an average particle size of 3-12 microns.
Claim 3
Dependent Claim

Claim 4
Independent Claim
128 words
A method of providing a protective finish to a vinyl substrate comprising applying to the vinyl substrate a vinyl protectant composition which is a hydrocarbon solvent free mixture of 5-60 percent by weight of a film forming polysiloxane which is selected from the group consisting of a polydimethylsiloxane fluid having a viscosity of 100 to 1000 centistokes and having a silanol functional phenyl based silicone resin having present in the resin CH 3 SiO 1 .5, (CH 3 ) 2 SiO, (CH 3 )(C 6 H 5 )SiO, and (C 6 H 5 ) 2 SiO siloxane units; 20-50 percent by weight of water; and 0.25-5 percent by weight of an amorphous silica in the form of fumed silica particles having an average particle size of 7-30 nanometers.
