OSI Quad Max sealant is primarily composed of a silyl-terminated polyether (STPE) polymer. This base is combined with various additives, including plasticizers to enhance flexibility, UV stabilizers to improve weather resistance, adhesion promoters to ensure a strong bond to different surfaces, and pigments to provide color. The specific formulation varies depending on the intended application and desired performance characteristics of the final product.
The selection of STPE as the primary component offers several advantages. It provides exceptional durability and flexibility, allowing the sealant to withstand expansion and contraction due to temperature changes and structural movement. The resulting product exhibits superior adhesion to a wide range of materials, including vinyl, aluminum, wood, stucco, and concrete. Furthermore, STPE-based sealants are generally low in volatile organic compounds (VOCs), contributing to improved air quality and compliance with environmental regulations. Historically, alternative sealants used less environmentally friendly and less durable compounds, making STPE a significant advancement.
