其实，封闭底漆具有较强的渗透力，不仅能封闭底材，清出毛刺，防止木材吸潮变形，防止木材中单宁酸渗透，还能承托上层底漆防止下陷，喷涂上层时不易产生气泡，使涂装达到最佳效果；

結果 (英文) 1:

Actually, the primer has a strong penetration, not only closed the substrate, out of burrs to prevent deformation of wood moisture, preventing the penetration of tannic acid in the wood, can also support the upper primer to prevent sinking, causes bubbles when spraying the upper, the coating to achieve the best results;

結果 (英文) 2:

In fact, the sealer has a strong penetration, not only closed the substrate, and clear the burrs prevent deformation of the wood to absorb moisture and prevent the wood tannins penetration, but also supporting the upper primer to prevent subsidence, spraying the top is not easy bubbles, so that the coating to achieve the best results;
