Abstract
Abstract A protective coating consists essentially of a polysiloxane copolymer characterized by being prepared by the reaction of a trimethyl end blocked polyamine silicone fluid including amino alkyl groups with a saturated aliphatic carboxylic acid to produce a polysiloxane copolymer including alkyl amine groups and either amide groups or amine salts or the combination thereof. The polysiloxane copolymer is utilized alone or with additives to produce a high gloss detergent resistant, and rust protective coating.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
80 words
A protective coating consisting essentially of a polysiloxane copolymer having the formula ##STR6## characterized by being prepared by reacting a trimethyl end blocked polyamine silicone fluid having the formula ##STR7## with a saturated aliphatic carboxylic acid having the formula C.sub.w H.sub.2w+1 COOH wherein Q is --C 3 H 6 -- to produce the polysiloxane copolymer and x is 10 to 1000, y is 2 to 200, Z is less the y and w is greater than or equal to 14.
Claim 2
Dependent Claim
80 words
A protective coating consisting essentially of a polysiloxane copolymer having the formula ##STR6## characterized by being prepared by reacting a trimethyl end blocked polyamine silicone fluid having the formula ##STR7## with a saturated aliphatic carboxylic acid having the formula C.sub.w H.sub.2w+1 COOH wherein Q is --C 3 H 6 -- to produce the polysiloxane copolymer and x is 10 to 1000, y is 2 to 200, Z is less the y and w is greater than or equal to 14.
Claim 3
Independent Claim
76 words
A method of making a protective coating which comprises the steps of mixing and reacting a trimethyl end blocked polyamine silicone fluid having the formula ##STR8## with a saturated aliphatic carboxylic acid C.sub.w H.sub.2w+1 COOH and producing a polysiloxane copolymer having the formula ##STR9## wherein Q is --C 3 H 6 --, x is 10 to 1000, y is 2 to 200, Z is less than y and w is greater than or equal to 14.
Claim 4
Independent Claim
76 words
A method of making a protective coating which comprises the steps of mixing and reacting a trimethyl end blocked polyamine silicone fluid having the formula ##STR8## with a saturated aliphatic carboxylic acid C.sub.w H.sub.2w+1 COOH and producing a polysiloxane copolymer having the formula ##STR9## wherein Q is --C 3 H 6 --, x is 10 to 1000, y is 2 to 200, Z is less than y and w is greater than or equal to 14.
Claim 5
Dependent Claim
51 words
A protective coating consisting essentially of a polysiloxane copolymer characterized by containing amine units of the formula ##STR10## and either amide units of the formula ##STR11## or amine salt units of the formula ##STR12## wherein W is greater than or equal to 14 and Q is --C 3 H 6 --.
Claim 6
Dependent Claim
51 words
