Also known as flushing fluids, these additives provide wear resistance while flushing and cleaning hydraulic systems, gear boxes, compressors, and other equipment.

Add this stabilizer to your gas tank to keep fuel fresh when stored for long periods. One fluid ounce of stabilizer treats 2.5 gallons of gasoline; each bottle treats up to 80 gallons.

This stabilizer contains nano-sized additives, which penetrate small surface imperfections to reduce wear and heat, extending the life of both the oil and the engine while improving performance.

For use in selective catalytic reduction (SCR) systems, this fluid reduces the air pollution from your diesel engine to help you comply with EPA guidelines. Commonly known as DEF, it contains urea to convert nitrous oxide (NOx) into water vapor and nitrogen for cleaner emissions. It meets ISO 22241-1 and American Petroleum Institute standards for diesel exhaust fluid.

When mixed into coatings, resins, polymers, and metals, these fillers enhance strength, conductivity, lubricity, and other physical properties.

Mix these additives with melted plastic, epoxies, or adhesives to make parts stronger and more wear resistant without adding much weight. You can use them in batches to tackle repairs and small parts instead of machining your part from a sheet, bar, or other shape.

Fiberglass

These additives increase a part’s strength and ability to withstand frequent blows. But, they’re not as strong or as lightweight as carbon fiber additives. They also block electric currents from passing through. Their short fibers are best for castings and foams to prevent cracking as resin shrinks. The amount you use to start should equal about 10-35% of your composite’s weight.

Carbon Fiber and Recycled Carbon Fiber

Often used in vehicles to increase fuel efficiency, these additives can double your composite’s strength to make stiff pieces that are stronger and lighter in weight than aluminum. The more you add to your mixture, the stronger it becomes. These additives also carry electric currents, so they’re good for directing electromagnetic energy away from electrical devices. However, they don’t direct electricity as well as metal. They’re made of chopped fibers, which makes them ideal for repairs and intricate parts. But, they’re not as strong or as stiff as materials with continuous fibers, such as fabric and tow.

The size of carbon fiber’s particles affects its ease of use and strength. The smaller the particle size, the less effort it requires to mix. On the other hand, larger particles make parts stronger and stiffer. Choose carbon fiber with smaller particle sizes when making intricate parts and repairs.

Recycled carbon fiber additives have a low carbon footprint to help you meet environmental goals. But, they’re not as strong or as stiff as standard carbon fiber additives.

Carbon fiber additives for thermoplastics bond with most melted plastic pellets, except PVDF. Shape your mixture into parts with compression and injection molding or 3D printing. You can shape your finished product multiple times without losing its strength. Start by adding 10% by volume to your mixture. Carbon fiber additives for thermosets mix with epoxies, adhesives, vinyl compounds, and phenolic. Use compression molding to turn your mixture into parts, or fill in cavities after curing without adding weight. You can’t shape your product once it’s cured. Begin with 5% by volume in your mixture.

Kevlar

Choose these additives when your application is likely to wear down your finished part—they improve a part’s ability to stand up to corrosion, bangs, bumps, and scrapes. They’re also used to reinforce points where honeycomb cores connect to fabric. To start, mix in 1 part Kevlar to 15 parts composite.
