Sikaflex PRO is a one-component, moisture-curing, elastic joint sealant. This multipurpose, permanently flexible polyurethane offers excellent adhesion to all common construction materials. It is cuttable, paintable, and sandable, providing high flexibility with low VC. Sikaflex-PRO is a thixotropic, polyurethane-based joint sealant that cures under the influence of atmospheric moisture to form an elastomeric material with adhesive properties, often without the need for priming the substrate.
Sikaflex-PRO is globally supplied by Sika and meets the most stringent sealant standards, such as US Federal Specification TT-S-00230C, Type II, Class A, BS4254 for one-part polyurethane-based sealants for the building industry, and JIS A 5758 for one-part polyurethane-based sealants for the construction industry. It bonds well to well-cleaned Sikaflex-PRO and exhibits excellent adhesion on all cement-based materials, brick ceramics, polyurethane, epoxy, most polyester, most metals, and most timbers. The product is highly durable, weather-resistant, and non-sagging on vertical and soffit joints up to 30 mm in width.
