Elastomeric Silicone Waterproofing
UNISIL is a high volume solids, pure elastomeric silicone coating that provides superior weatherproofing, ultraviolet resistance and fire retardancy over polyurethane foam insulation and other appropriate substrates. The fire retardant chemicals are permanently locked into the cured coating and will not leach out upon extended aging. UNISIL is a single component elastomer that exhibits a rapid cure when exposed to ambient conditions. Long term elastomeric properties are retained under all types of weather conditions, from sub-zero temperatures to high heat in excess of 300'F (149'C). Aged UNISIL roofs have been tested and certified to meet EPA guidelines for ENERGY STAR compliance. Use of this product will help save energy and reduce electrical costs. UNISIL is also sustainable. Through periodic recoating, the elastomeric coating can be maintained throughout the life of the building.
UNISIL is designed for protecting a wide range of substrates from the effects of moisture intrusion and weathering. UNISIL is particularly effective as a protective coating over polyurethane foam on new or existing roofs, and hot or ambient storage tanks. It provides a barrier to the effects of degradation caused by normal weathering, aging and ultraviolet exposure. UNISIL also achieves excellent adhesion to primed concrete, masonry, metal and wood surfaces. |
