Mechanical Strength & Durability

Impact Resistance

If you use unsaturated polyester resin, your wood gets strong protection. The resin makes a hard layer on top of the wood. This layer helps stop dents and scratches from happening. It keeps your wood safe during daily use. Lab tests show how well this works. The table below shows how three types of unsaturated polyester resin do with heat and impact.

A bigger HDT means the coating can take more heat before it gets soft. A higher Barkel Number means it is better at stopping damage from hits. You can see that AUPE I and AUPE II have higher numbers. This means they work better for your wood.

Long-Term Wear Protection

You want your wood to last a long time. Unsaturated polyester resin helps make that happen. It gives great protection against things rubbing or scratching the wood. This means your wood will not look worn out, even in busy places. The resin sticks well to the wood fibers. This keeps the surface smooth and safe from harm. You get both strength and protection from wear. Many people see that their wood still looks good after years. This strong protection makes unsaturated polyester resin a good choice if you want your wood to stay nice and strong.

Chemical & Moisture Resistance

Water Repellency

You want your wood to stay dry and strong. Unsaturated polyester resin helps you achieve this goal. When you coat wood with this resin, you create a barrier that keeps water out. This barrier stops moisture from soaking into the wood fibers. As a result, your wood does not swell, warp, or rot easily.

Let’s look at how well different types of unsaturated polyester resin block water. The table below shows the water absorption percentage for three resin types. Lower numbers mean better water resistance.

You can see that AUPE II has the lowest water absorption. This means it gives you the best protection against moisture. When you use AUPE I or AUPE II, you help your wood last longer, even in damp places.

Tip: For outdoor furniture or decking, choose a resin with a low water absorption rate. This keeps your wood looking new and prevents damage from rain or humidity.

Chemical Protection

You may worry about spills or cleaning products harming your wood. Unsaturated polyester resin gives you peace of mind. The resin forms a tough shield on the wood’s surface. This shield resists many household chemicals, such as cleaners, oils, and mild acids.

When you use this resin, you make your wood easier to clean. Stains and marks do not soak in. You can wipe them away without harming the finish. This makes unsaturated polyester resin a smart choice for kitchen counters, tables, and work surfaces.

• Protects against accidental spills

• Keeps wood safe from harsh cleaners

• Reduces the risk of permanent stains

With this level of chemical resistance, you help your wood stay beautiful and strong for years.

Surface Finish & Appearance

Gloss & Smoothness

You want your wood to look its best. Unsaturated polyester resin helps you achieve a high-gloss finish that stands out. When you apply this resin, you create a surface that feels smooth to the touch. The resin fills in tiny gaps and covers the wood evenly. This makes the wood shine and look polished.

• High-gloss finish: Your wood gets a mirror-like shine.

Tip: If you want your wood project to look like it came from a professional shop, use unsaturated polyester resin. It gives you a finish that impresses everyone.

You can see the difference in the table below:

A higher gloss unit (GU) means more shine. A lower micron value means a smoother surface. Unsaturated polyester resin gives you both.

UV Protection & Color Retention

Sunlight can damage wood over time. The UV rays cause fading and yellowing. Unsaturated polyester resin helps you stop this problem. The resin contains special additives that block UV rays. These additives protect the wood and the color.
