Liquid liners Dinitrol 479 (Dinitrol)
Dinitrol 479 is a unique composite material that has many applications. First of all, it is used as a liquid soundproofing, which we have already talked about on our autoportal Vodi.su. One of the names of Dinitrol is liquid fender liner, as it protects the bottom well from corrosion and gravel impacts.
Those people who have foreign-made cars are well aware that manufacturers traditionally install fender liner (lockers) made of plastic, fiberglass or polypropylene. This is a good solution for the roads of France or Germany, which are considered among the best in the world. But for Russia, fiberglass as a material for lockers is not the best protection. That's when various composite materials come to the rescue.
Dinitrol 479 - triple protection for the underbody and wheel arches
The first thing that excites every driver is the protection of the body from corrosion. If the paintwork can be treated with wax and various types of polishes, then a drug such as Dinitrol will become one of the available products for the bottom. Budget cars often come to our market almost bare bottom. At eminent factories, they use ordinary regular paint, plastisol to cover joints and plastic lockers for wheel arches.
All these funds can last a maximum of a year - the owners of Chinese cheap cars know that the bottom begins to rot in just a couple of months of driving on our roads.
Dinitrol is the best choice for comprehensive protection.
It is applied:
- to ensure comfortable silence in the cabin - after processing, the noise level is noticeably reduced by 40 percent;
- as an anti-corrosion coating;
- as liquid fender liners to provide anti-gravel protection.
Consumers are attracted to this particular product also because it is relatively cheap - a five-liter bucket costs about 3500-4500 rubles, a 1,4-kilogram can can be bought for 650-1000 rubles. For the complete processing of the bottom, including protection of the engine, gearbox, tank, gearbox, approximately 5 kilograms of this composite material will be needed.
Chemical composition and properties
Dinitrol is a black viscous material based on wax and bitumen, also included polymeric substances, corrosion inhibitors and plasticizers for ease of application.
It is characterized by the following properties:
- high level of adhesion - it keeps on almost any type of surface;
- plasticity is preserved even after drying, that is, it will not begin to crumble, even if a dent forms on the bottom from a stone impact;
- thixotropy - during application, streaks and drops do not form on the bottom, that is, it is spent as efficiently as possible;
- resistance to low and high temperatures - able to withstand temperatures up to + 200 ° C;
- it does not contain aggressive substances and solvents that could damage the paintwork;
- high chemical resistance to saline solutions and reagents.
Well, the most important quality is an excellent anticorrosive agent, that is, it not only isolates corrosion, but also prevents its further spread.
Please note that the qualities of Dinitrol are confirmed by various certificates, including international ISO 9001, QS 9000, ISO 14001. It is used as an anti-corrosion protection in many automotive industries.
Steps for applying Dinitrol 479
First of all, the bottom is completely cleaned of dirt; at the service station, Karcher-type washers are used for this purpose to supply water under high pressure. Then it is dried with compressed air. When the bottom is completely cleaned, experts can identify areas that require special protection.
It should be said that a lot of different drugs are produced under this brand:
- Dinitrol LT - moisture-displacing wax composition;
- Dinitrol 77B or 81 edge waxes;
- Dinitrol ML is a corrosion preservative;
- Dinitrol Termo and 4941 are high wear formulations.
Well, actually the universal coating Dinitrol 479, which most often acts as a "silent", combining other qualities.
Processing the bottom with all these compounds guarantees protection against corrosion and minor damage for 8-12 years.
You can apply these products at home with a spatula or brush. It is best to apply in several layers, allowing each previous layer to dry. You can use spray guns, but not spray guns, because the material will simply clog fine nozzles. Before applying with a sprayer, the product must be heated to 40-60 degrees.
After completion of work, the layer thickness should not exceed 2 mm. True, it is allowed to apply a layer up to 5 millimeters thick when it comes to freight transport, but the drying time is significantly increased. Complete drying occurs in 20 hours, you can blow the coating with air from a car compressor. Although two hours after application, you can drive a car, but it is not advisable to accelerate to 70 km / h.
Sound insulation manufacturer's warranty - 7 years, subject to proper application.
