Constant monitoring of the product temperature is necessary as the powder coat cures. Powder coatings powder coatings can be divided into two types.
Understanding these factors will ensure that your finish is durable and your powder coating color turns out as you expected.
Powder coating temperature. Most powder coatings have a particle size in the range of 2 to 50 μ microns a softening temperature tg around 80 c a melting temperature around 150 c and are cured at around 200 c. For minimum 10 minutes to 15 minutes exact temperatures and times may depend on the thickness of the item being coated. When the substrate reaches full temperature it will conduct heat into the coating and the powder will begin to cure.
Most powder coatings like thermoset powders normally cure at temperatures of 200 c 390 f for 10 to 15 minutes before being set aside to cool. This underscores the importance of making the right choices in powder coating providers. For both types a free flowing dry powder is applied to a substrate usually metal which is then heated to a temperature that allows the powder to melt flow and form a coating.
Temperature needed for powder coating. It has superior corrosion and abrasion resistance and has been tested in these rough environments. The curing process also called crosslinking is necessary to strengthen the coating.
A cured thermoset powder coating will not re melt upon further heating. To ensure proper time and temperature it is often best to test using a datapaq or similar device to provide actual performance data. Temperature is usually measured with infrared thermometers.
Each of these powders has their own set of benefits and challenges but we bring our long history of experience and expertise to help you find the option that will best meet your. 1 the temperature of your oven and product and 2 how long to let the part cure. Two key factors to consider at when curing powder coating are.
Particle size plays an important role in the application process. Does particle size make a difference in powder coating. Crest coating offers a wide variety of specialty powder coatings including high temperature powder coating anti graffiti antimicrobial translucent and more.
Cooling the oven before putting a load of parts in lengthens the total cycle time without adding any benefit other than the operator does not have to get close to high heat. Normally you want to lose as little temperature in the. Incorrect timing or temperature settings may lead to under or over curing.
High temperature powder coating is a series of silicone based functional coating providing excellent heat resistance corrosion resistance and high color retention this coating is designed to excel in harsh environments such as in the automotive and industrial industries. Determining the correct temperature and time to cure your powder coating.
