Technical field
The invention belongs to chemistry painting industry field, and in particular to a kind of high durable, high endurance automotive hub coating varnish
And preparation method thereof.
Background technology
Finishing varnish is commonly called as gloss oil, there is very high frequency of use in modelling.Commonly used in civilian model, finished goods is improved
Brightness.Complete in full car, after posting note paper, according to 1:3 ratio is blended into solvent dilution, uniformly sprays in car
Surface, several times after, it is possible to obtain satisfied result.Automobile Coatings are generally by high-weatherability hydroxy acryl acid
Resin, special addition agent and organic solvent are dispersed through modulation and form, and are two-component product.It need to be matched during construction with curing agent.
Key property is transparency height, and gloss is high, and weather resistance is excellent, and adhesive force is good, and hardness is high, and richness is good, and excellent is water-fast, resistance to
Gasoline, chemical resistance, can from it is dry also can low temperature drying, it is mainly used for medium and high classes automobile, palace car, station wagon etc.
The surface Lacquer finish paint of advanced vehicle.Traditional Automobile Coatings modulation is complicated, and water resistance is poor, resistance to acid and alkali reaches all the time
Less than theoretical value, more troublesome is that the construction needs that get up are repeated several times coating.
