Abstract
Abstract Disclosed are high wet-friction, highly adherent, non-abrasive elastomeric compositions producing smooth, slip-resistant coatings on surfaces, containing as primary components a thermoplastic rubber block copolymer and a petrolatum, and optionally independently including a plasticizer such as a hydrogenated polybutene, a tackifier such as polyisobutylene or a hydrocarbon resin, an antioxidant or a UV light absorber, in a carrier organic solvent, and containing no abrasive filler or particulate additives.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
55 words
A composition producing high wet-friction, highly adherent, slip resistant surfaces to which said composition is applied comprising a homogeneous mixture of: a thermoplastic rubber block copolymer; a slip resistant effective amount of a petrolatum; and, optionally independently, an effective amount of a plasticizer or a tackifier, dissolved in an organic solvent carrier, without abrasive fillers.
Claim 2
Dependent Claim
55 words
A composition producing high wet-friction, highly adherent, slip resistant surfaces to which said composition is applied comprising a homogeneous mixture of: a thermoplastic rubber block copolymer; a slip resistant effective amount of a petrolatum; and, optionally independently, an effective amount of a plasticizer or a tackifier, dissolved in an organic solvent carrier, without abrasive fillers.
Claim 3
Dependent Claim
13 words
A composition of claim 1 wherein said copolymer comprises a styrene/ethylene/butylene/styrene tri-block copolymer.
Claim 4
Dependent Claim
12 words
A composition of claim 1, wherein said optional plasticizer is a polybutene.
Claim 5
Dependent Claim
16 words
A composition of claim 1, wherein said optional tackifier is a polyisobutylene or a hydrocarbon resin.
Claim 6
Dependent Claim
34 words
A composition of claim 1, wherein said organic solvent comprises a mixture of one or more solvents selected from the group consisting of toluene, n-propyl acetate, lactol spirits, 1,1,1-trichloroethane, VM&P naphtha, and lower alkanes.
Claim 7
Dependent Claim
31 words
A composition of claim 1 wherein said block copolymer, said petrolatum and said optional plasticizer are present in amounts of about 12-24, about 25-35, and about 20-35 parts by weight, respectively.
Claim 8
Dependent Claim
51 words
A composition of claim 6, wherein said organic solvent comprises a mixture consisting essentially of toluene, n-propyl acetate and lactol spirits, each as a part by weight about equal to or greater than the sum total of the parts by weight of said block copolymer, said petrolatum, and said optional polybutene.
Claim 9
Dependent Claim
17 words
A composition of claim 1, further comprising a wet friction increasing effective amount of a methylmethacrylate copolymer.
Claim 10
Dependent Claim
52 words
A composition of claim 6, further comprising one or more materials selected from the group consisting of a 0-20 parts by weight of a tackifier hydrocarbon resin, 0-60 parts by weight of a tackifier polyisobutylene, 0-1 part by weight of an antioxidant, and 0-1 part by weight of an ultraviolet light absorber.
Claim 11
Dependent Claim
95 words
A composition comprising a homogeneous mixture of about 10-24 parts by weight of a styrene/ethylene/butylene/styrene tri-block copolymer, about 25-35 parts by weight of a petrolatum, about 20-35 parts by weight of a polybutene plasticizer, about 70-100 parts by weight of toluene, about 70-100 parts by weight of n-propyl acetate, about 150-200 parts by weight of lactol spirits, 0-30 parts by weight of a hydrocarbon resin tackifier, 0-60 parts by weight of a polyisobutylene tackifier, 0-1 part by weight of an antioxidant, and 0-1 part by weight of an ultraviolet light absorber, and without abrasive fillers.
Claim 12
Dependent Claim
95 words
A composition comprising a homogeneous mixture of about 10-24 parts by weight of a styrene/ethylene/butylene/styrene tri-block copolymer, about 25-35 parts by weight of a petrolatum, about 20-35 parts by weight of a polybutene plasticizer, about 70-100 parts by weight of toluene, about 70-100 parts by weight of n-propyl acetate, about 150-200 parts by weight of lactol spirits, 0-30 parts by weight of a hydrocarbon resin tackifier, 0-60 parts by weight of a polyisobutylene tackifier, 0-1 part by weight of an antioxidant, and 0-1 part by weight of an ultraviolet light absorber, and without abrasive fillers.
