Safety First: The Heat and Shock Resistance of Plastic Coating

Heat-Resistant Plastic Coatings

Because they must be able to withstand either preheating, heat curing, or both, plastic coatings are most commonly used on metal parts. That ability to easily tolerate the temperature of the coating process is also what makes a heat-resistant coating so important — helping prevent damage or injury. Of course, not all plastic coatings can perform equally well in high-temperature environments.

Less Heat-Resistant Coatings

The majority of commonly used polymer coatings will perform well at temperatures up to around 200°F, at which point many start to degrade.

More Heat-Resistant Coatings

Most epoxy coatings have heat tolerances around 350° to 400°F, while many fluoropolymer coatings, such as Halar, have a slightly higher tolerance from about 350°F to around 600°F. 

Shock-Resistant Plastic Coatings

Most polymers are poor conductors of electricity, making them good at insulating electrical wiring, components, and even tools for working around both low and high voltages. In particular, plastisol coatings are commonly used for high-voltage tools and parts such as bus bars, while others, such as nylon, epoxy, and Halar, are often used to minimize friction, and provide impact, abrasion, and resistance to corrosion and moisture. These plastic coatings help minimize fire risk from a buildup of electrical current, dust, dirt, or debris, prevent dangerous contacts among components and, more importantly, protect people.
