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.
Claims11
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.
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.
