While we need to provide the suitable coating for wood products, such as a variety of furnitures in our house, we usually choose to use the varnish. Generally speaking, there are different types of varnishes: the oleoresinous types and the sprit types. The petroleum resin plays an important role in the production of varnish. With the agitating of the petroleum resin and the additives mixed to speed the process, the varnishes are made.

When the varnish on the surface of the destined item become dry, a hard and semitransparent film would be formed. The wooden products would be protect from the worms and rotting. In addition, varnishes are endowed with the ability of non-conducting. So, they could be used to insulate wire and cable. At the same time, varnishes could be applied to coat the metal products, such as the food metal containers and protect them from rust. Further more, have you noticed that some types of papers are brighter and resistant to moisture? Well, that is because of the use of varnishes.

The petroleum resin could be used to to make other types of paint as well. When it come to the production process of varnishes, in order to speed the process, the mixtures of the resin and the oil are heated to a certain temperature and while the mixtures cool down, they seem to be like the turpentine.

In order to speed the drying process, driers such like cobalt or lead could be used. When the varnishes have finally hardened, they could last for a long time. And the type which is designed with longest lifespan and the hardest surface it the urethane varnishes.

While you need to use the varnishes made from petroleum resin, you should better consider your requirements. For example, if you are going to use them to cover the indoor items, the short varnishes which could dry and harden more quickly is your best choice. And if you plan to protect the outdoor devices from water, there is not other better choice that the long varnishes. They could be used to provide a more flexible surface, but they need more time to harden.
