Soudal PRO 40P is a professional-grade, one-component polyurethane adhesive designed for high-strength bonding of wood and construction materials. This ready-to-use adhesive offers excellent water resistance (D4 classification), making it suitable for both interior and exterior applications exposed to moisture and harsh weather conditions. It features a unique foaming expansion action that penetrates and fills gaps, pores, and uneven surfaces, ensuring maximum bonding strength and durability. The adhesive cures through moisture reaction, forming a tough and long-lasting bond that can withstand heavy loads, environmental stress, and temperature variations. Ideal for joinery, carpentry, furniture production, and structural wood bonding, it is especially effective on damp or humid wood surfaces and provides reliable performance in demanding industrial and construction environments.
