Second Skin Protection against Low Temperature Exposure

摘要

Work was undertaken toward the development of creams, ointments, etc., which when applied to the hands and part of the face would offer protection against injurious effects from exposure to low temperatures. Vinyl plastisols with good viscosity stability have been developed. Accelerators are described with which these plasticols can be fluxed, at temperatures feasible for the skin, to form either dense or foamed coatings with satisfactory physical properties including flexibility at -65 F. New silicone rubber coatings were found which cure at room temperature. These coatings cured in either foamed or dense form show no loss of elastomeric properties when cooled to -65 F. A two layer system is described consisting of a soft, resilient layer of plasticol or silicone rubber foamed on the skin for thermal insulation and thin dense covering layer of plastisol or silicone rubber for abrasion resistance.
