SI-TUFF™ Silicon Carbide Whiskers

SI-TUFF™ Performance Silicon Carbide is a new type of reinforcing additive for protective coatings. It toughens coatings, increases wear resistance, and extends their service lifetime. It may be used in liquid and powder coatings of all chemistries and application methods, and it is safe for food contact.

Watch this video to see how SI-TUFF™ reinforces your coating:

If used properly, SI-TUFF™ is expected to increase service lifetime by 20-50%. Some customers have improved performance by 70%. The primary benefit of SI-TUFF™ is improved scratch and abrasion resistance, which results in increased service lifetime. Secondary benefits include enhanced thermal conductivity and stability, impact resistance, and hardness. If you think you already have the toughest coating, it can almost always be made tougher with SI-TUFF™.

SI-TUFF™ Performance Silicon Carbide is primarily used when the coatings formulator is challenged with improving wear resistance without compromising other critical properties. SI-TUFF™ is uniquely valuable for these applications because it improves wear resistance at low loading levels, such that it does not affect other properties including non-stick, friction, and flexibility. For example, it may be used in non-stick cookware and bakeware coatings without affecting release properties, or it may be used in piping coatings without decreasing flexibility and impact resistance.

The best way to get started is by reading the Applications Guide.The objectives of this guide are to:
