Before discussing specifics on how to use SI-TUFF™ for a given coatings application, it is important to understand the engineering behind why it works.
SI-TUFF™ is effective because of its unique combination of hardness, mechanical strength and high aspect ratio geometry. It works by forming an interlocking, reinforcing network in the coating. This reinforcement distributes stresses and abrasion forces into multiple, smaller force components over long ranges. The end result is reduced localized coating wear and damage, and a longer service lifetime.

Other mineral additives are often used to reinforce coatings, including SiC particles. SiC particles are effective at improving wear resistance, however they do not provide long range force distribution. Compared to SI-TUFF™, the result is weaker reinforcement and greater localized forces and damage.
SI-TUFF™ offers higher performance at lower loading levels than other additives. Increasing additive loading levels typically affects other coating properties, and a trade-off must be made. SI-TUFF™ significantly improves wear resistance at low loading levels; in fact, it may be used in coatings applications that traditionally avoid mineral additives completely. For example, industrial bakeware coatings can be toughened without any loss of release properties.
