Paragraph starter

Research indicates that the substrate material plays a critical role in the adhesion strength of surface coatings. For instance, studies on wood-based composites have shown that Medium Density Fiberboard (MDF) offers significantly higher paint adhesion compared to particleboard, with measured strengths of up to 3.62 MPa. This suggests that prioritizing MDF in design projects requiring painted finishes can lead to more durable and aesthetically stable products.
