Development of coating for formaldehyde scavengers in wood composite

Wood composite is also known as wood engineering. This field is available due to its ability to overcome the current limitation faced by applying natural lumber wood. The many advantage that wood-composite have over natural lumber makes it more desirable in long-term usage. In the production of wood...
