The primary purpose of using micro-powder wax in wood finishes is to protect the wood while enhancing its tactile and visual appeal. Its key benefits can be summarized as follows: Improved Surface Feel and Smoothness: The most noticeable effect of micro- powder wax is that it alters the feel of the finish, making the wood surface more pleasant to the touch. Improved Smoothness and Anti-Sticking Properties: The wax powder reduces the coefficient of friction on the finish surface, making it smoother and preventing the finished surfaces of furniture pieces from sticking together and sustaining damage during stacking or packaging. Excellent Scratch Resistance and Wear Resistance: Micro-powder wax forms a protective layer on the finish surface that effectively resists scratches and wear during daily use, with particularly notable results in water-based formulations.

DINP is a C9 phthalate plasticizer, produced from INA (Isononyl Alcohol) and PA (Phthalic Anhydride). It appears as a clear, colorless, and almost odourless oily liquid with solubility in most organic solvents. Compared with DOP, DINP typically requires a slightly higher dosage to achieve similar plasticizing efficiency. However, it offers superior electrical insulation, durability, migration resistance, and low-temperature flexibility. The longer carbon chain structure improves stability and reduces volatility. At the same Phr level, DINP- plasticized products generally demonstrate improved tensile strength, elongation, durability, and low-temperature flexibility than DOP-plasticized products.

DOP phthalate plasticizer produced from reaction of 2EH (2-Ethylhexanol) and PA (Phthalic Anhydride). It appears as a colorless, transparent oily liquid with high stability, high boiling point, and solubility in most organic solvents. DOP is the most commonly-used primary plasticizer in the PVC industry, featuring high plasticizing efficiency, well-balanced properties, and cost-effectiveness. The formulation dosage can reach up to 150 phr depending on product requirements.
