The BOSS Product Line: Engineered for Versatility

Accumetric's BOSS series spans multiple sealant chemistries, giving professionals and DIYers the right formulation for every job. Key product lines include:

• BOSS 125 Multi-Seal: A multi-purpose, one-part sealant formulated with USP™ Technology to create a highly durable, flexible seal suited for a wide range of construction and repair applications.

• BOSS 365 100% Acrylic Elastomeric with Silicone: Specifically formulated for high joint movement, this paintable, mildew-resistant sealant cures to a tough, flexible, non-yellowing seal. Its smooth, creamy consistency makes it easy to tool for both interior and exterior applications including crown molding, chair rails, and all exterior trim.
• BOSS 378 Silicone Sealant: A silicone-based caulk designed for RV and mobile home use, offering reliable sealing for HVAC ductwork, window gaps, fixtures, and lighting.

Accumetric (also known as Soudal Accumetric) brings industrial-grade sealant expertise to both professional tradespeople and hands-on enthusiasts.
