Anticorrosive wood is a kind of wood-based board made of pressing plate. If the moisture content of preservative wood is not well controlled, some bad situations will often occur, endangering our application. What are the specific hazards? The following anticorrosive wood manufacturers will introduce to you.
1. Drying and curing of hazardous coatings
Due to the high moisture content of the anticorrosive wood, the contact area between the coating and the anticorrosive wood is in a wet state, endangering the evaporation of the diluent and the chemical cross-linking reaction between the resin and the curing agent. Therefore, it will also endanger the drying speed and complete curing of the coating, resulting in non drying or incomplete drying.
2. Damaged paint adhesion
With the desorption of water, the coating will crack, expand and separate, resulting in poor adhesion.
3. It causes the growth of fungi
Because the high moisture content will lead to the growth of decaying fungi, molds and discoloration bacteria, resulting in the decay and damage of anticorrosive wood.
4. Whiten wet coating
When the preservative wood is not dry well, the water in the wood will enter the coating under the evaporation of diluent, which will often lead to the whitening of the wood. If moisture cannot be released, the transparency of the paint will be damaged by fog.
5. Cause pinholes and bubbles
Because polyurethane coating is easy to react with water and produce gas. When the gas escapes, bubbles will be generated, resulting in pinholes and film defects.
6. Damage unique color
High moisture content will damage the coloring of preservative wood. When the moisture content of anticorrosive wood changes greatly, the paint will change color with the collapse of anticorrosive wood, resulting in uneven color.
