Curing the Paint
5. Curing the Paint

Most high temperature paints operate in the same way. They use a resin which dries at room temperature, giving the paint the initial properties seen on an un-used stove. Then, when the stove is burned, this air-dry resin burns away. At the same time, the silicon resin (silicone gives the paint it’s high heat resistance) in the paint will not cure until it is heated to high temperatures. This occurs at about the same time the air-dry resin is burning. We have found that this "transition" takes place at about 475ºF.

It takes 3 burns in the stove to cure the paint with heat. The first 2 should be at about 250ºF for 20 minutes each. The 3rd burn should be at 450ºF for 45 minutes. Do not burn at full heat, 900ºF or more, for the first burn, as it will shock the paint. At the time of the first burn there will be a ring on the top of the stove. Within this ring the sir-dry resin will have burned away and the silicon resin has cured. Outside this ring the silicon resin is still uncured and the air-dry resin is still there. On the ring, however, you will notice that the paint is soft- - even wet. Do not touch the paint with anything (like a teakettle or trivet) while it is curing. This is where the transition happens. After the stove has been burned about three times, the entire surface, which gets hot, will have cured, and there will be no further changes. It is important to warn your customers to ventilate the house during these initial burns. Although the smoke is primarily Carbon Dioxide, there are other components of the smoke, which make it smell bad and may physically irritate some customers. It is not toxic. We have had it tested. It is only carbon dioxide, but it displaces oxygen, so ventilate the room while curing. These problems will go away after the first few burns, depending on the duration and the surface temperature of each burn.

STOVE BRIGHTâ is a little glossy when first applied. It loses some of this gloss when it is cured. This means that a stove, which has begun its cure cycle, will sometimes show a ring that is visible when curing. Often, the cured paint will look lighter in color, because it is "flatter". Again, after the paint is cured, this condition will not be as visible. If this is a major problem, one solution is to use STOVE BRIGHTâ #6304 Flat Black paint initially. The gloss paints have shown better scuff resistance and appearance after curing, even though the cured finish is flatter in appearance.
