1. Zinc Stearate What is in wood paint?

Zinc Stearate is a zinc salt of stearic acid, white, fine powder, insoluble in water. In the wood coating industry, it is widely known as an effective sanding aid and surface leveling agent.

2. Outstanding benefits when used Zinc Stearate for wood paint

Optimizes sanding and anti-sticking properties

This is the most core value of the product. During the process of sanding the wood surface after priming, friction will generate heat, causing the paint resin to soften and adhere tightly to the sandpaper. Zinc Stearate with a special crystal structure will create a dry lubricating film, preventing direct contact between paint resin and sandpaper. As a result, the paint powder peels off easily in the form of fine dust, helping to prolong the life of the sandpaper and save significant labor time.

Controls gloss and smoothes the paint film surface

Zinc Stearate Has the ability to disperse evenly in a solvent environment, helping to fill small defects on the surface of wood fibers. It helps control the gloss of the paint film, creating a smooth, uniform surface effect without losing the natural beauty of the wood grain. This is especially important for high-end wood paint lines that require high sophistication.

Effective anti-sedimentation and seed hanging properties

In paint formulations, pigments or fillers often tend to settle to the bottom of the barrel and harden after a period of storage. Zinc Stearate acts as a stabilizing agent, helping to maintain suspension of solid particles. Thanks to that, the user only needs to stir gently to achieve a homogeneous mixture, ensuring stable paint quality.

Enhances water resistance for wooden surfaces

Thanks to the inherent hydrophobic properties of the Stearate base, this additive helps improve the moisture resistance of wood surfaces. This helps protect wooden furniture products better in hot and humid climate conditions in Vietnam, limiting blistering or mold on the paint film after a period of use.

Excellent compatibility with NC and PU paint systems

Products at Mega are refined to high purity, ensuring they do not cause side effects such as paint discoloration or "fisheye" phenomenon. Stable melting point helps the paint film maintain its physical and mechanical properties even in high-temperature industrial production environments.

3. Instructions for effective application

Zinc Stearate often added to the dispersion stage in the paint manufacturing process. Depending on the purpose of use (primer or topcoat), the recommended ratio usually ranges from 2% - 5% of the total formula weight. Using the correct ratio will help the paint film achieve a natural matte shine without affecting the adhesion of subsequent paint layers.
