Alkyd primers are synthetic resin-based products that provide excellent protection against moisture and corrosion. They create a strong, durable coating that effectively penetrates the surface and improves adhesion to finishing coats. Alkyd primers are especially effective for metal and wood surfaces, as they protect against environmental influences, preventing rust on metal and deterioration of wood. These primers are suitable for both interior and exterior use, providing long-lasting protection and improving the resistance of finishing coats to external influences.
