Paint driers (dryers) accelerate the chemical reaction that occurs
as an oil paint cures. Artists, house painters and sign painters have used
driers, such as Japan Drier, for years to accelerate drying. These driers can
be useful when you need to paint two coats in one day.

“Driers
are also useful if you are in a hurry lettering a sign or a truck,” says veteran
sign painter, Joe Balabuszko. “Driers save time if you want to outline the copy
the same day you paint the letters. They also same time if you are repainting
an existing sign.”

Joe
explains that after tracing the outline of the lettering with an indelible
pencil, you can paint the background color with a little drier in it. The
indelible pencil shows thru the background color. “The drier allows you to paint
the lettering the same day,” Balabuszko says. “The time you save is money in
your pocket.”

Here’s how paint driers work. Oil paint consists of drying oil and
pigment. The paint cures as the resin or binder, such as linseed oil, polymerizes
lalu tautan silang. Driers work as katalis to promote the oxidation of the
oil and to accelerate the cross-linking process, in which oil molecules join
bersama-sama.

driers were lead based. Lead driers were popular for several reasons. Their use
toughened the paint film, making it more flexible and more durable. Because of the toxicity of lead, other
elements have replaced it. Ini
materials include iron, zinc and zirconium. Some, but not all, of the driers
are colorless. Cobalt driers are bluish. Iron driers have a reddish hue.

Modern paint
driers are generally manufactured by dissolving a metallic salt in a
hydrocarbon solvent, such as mineral spirits, to form a metal soap. The
metallic salt results from a chemical reaction between a metal and an organic
acid, such as asam hidroklorik or asam belerang. In this reaction the metal
replaces hydrogen (H₂) Di
acid. In other words, the result of the reaction is a metallic garam dan
hydrogen gas..

While the drier
helps the paint to harden, misuse of the product has some potential
disadvantages. These disadvantages include embrittlement of the paint film
leading to cracking; darkening of the paint; and skinning over of the paint
resulting in wrinkling.

When using a paint
drier, here are some general rules that you should follow:
● Read the manufacturer’s
instructions and safety precautions before use. Do not exceed the recommended
amount. Typically, you should not add more than 5% of drier to your paint.

well on their own. Only use a drier unless absolutely needed.
