PRODUCT DATA SHEET DESCRIPTION Sikaflex®-290 DC PRO is a 1-component polyurethane based joint sealing compound, specifically formulated for caulking joints in traditional timber marine decking. It exhibits excellent weathering resistance and is therefore well suited for highly exposed open joints within the maritime environment. The sealing compound cures to form a flexible elastomer which allows a fast and easy sanding process. Sikaflex®-290 DC PRO meets the requirements set out by the International Maritime Organisation (IMO). PRODUCT BENEFITS ■ Excellent weathering resistance ■ Robust and durable ■ Easy and fast sandable ■ Ideal flow behavior for application ■ Long toolability ■ Unique aspect ■ Resistant to seawater and fresh water AREAS OF APPLICATION Sikaflex®-290 DC PRO is designed for caulking of joints in traditional timber decking for boat-, yacht and commercial ship constructions. This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

PACKAGING INFORMATION CURE MECHANISM Sikaflex®-290 DC PRO cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower (see diagram 1). CHEMICAL RESISTANCE Sikaflex®-290 DC PRO offers effective longterm resistance to fresh water, seawater and mild aqueous cleaning agents. The sealant is not resistant to solvents, acids, caustic solutions and chlorine containing cleaners. A brief contact with fuels or lubricants has no significant effect on the durability of the sealant. METHOD OF APPLICATION...
