Bostik STR220A Multipurpose Sealant is a Silyl Modified Polymer (SMP)-based all-purpose elastomeric sealant, suitable for bonding and sealing joints and seams.
STR220A is developed for bonding and sealing in various industries, including bus, RV, and trailer assembly. The product adheres well to most coated and uncoated metals, glass, PVC, polyester, and coated wood. Substrates should be clean, dry, and dust/grease free prior to bonding. Low surface energysubstrates, like polyolefins and PTFE, mustbe treated before bonding. The use of Prep M is recommended for higher adhesion strength. For bare wood and other porous substrates, the use of Prep G is recommended. Consult the technical data sheets for Prep M and Prep G for more details.
