Component B Topsealer® DSV 1L LQ

Component B Topsealer® DSV 1 L is an aliphatic isocyanate hardener formulated as part of the two-component Topsealer® DSV sealing system, ideal for protecting surfaces coated with microcement, wood, parquet, or decorative concrete. Thanks to its high chemical and mechanical resistance, this component guarantees a durable seal against abrasion, scratching, and cleaning agents, without altering the color or finish of the coating. It is part of the Topsealer® family of high-performance varnishes for interiors and exteriors.
