Flexible protective and lustrous spray gel dressing composition
View Patent ↗A protective dressing composition which imparts a lustrous and glossy appearance to a flexible or elastic rubber or plastic surface includes water, silicone fluid, a polymeric acrylic emulsifier to hold the silicone fluid in dispersion in the water and a UV stabilizer. Further, the composition is substantially free of nonpolymeric surfactants. The coating does not exhibit stickiness, attract dust or other contaminants, and resist cracking and peeling. The composition provides of a shiny protective coating suitable for application to metal, plastic, wood, and painted surfaces, and is especially well suited for use on flexible substrates such as automotive tires, bumpers, rubber, trim, vinyl, and the like. The coating maintains the flexibility of the coating at low temperatures and reduces and/or eliminates the tacky property on the surface. The acrylic polymer emulsifier does not re-emulsify with rain (water) providing a durable protective coating. The instant composition utilizes a polymer, which acts as an emulsifier and does not require a separate surfactant to hold the solution in suspension as required by conventional formulations, which require a surfactant to form an emulsion.
