How to apply car paint

Sunday, July 5th, 2009

If you want to paint their cars in their own trend and to achieve that look, so it is important to get all the information you can get in the paint you use’ Will have to choose which tools to use wisely, select the part of the garage is well ventilated, ie where there is free passage of air’

All the paintings are not the same car but there are some qualities that you need to check before buying the car’ Any paint that should not be used polished after application, unless it is of poor quality’ The painting will always be flexible, without the use of flex additives’ To improve the coverage of paint, use paint as a first undercoating’

When you’re dealing with a minor repair or a full recovery, preparation is absolutely necessary’ Clean the area used’ There are two types of pollutants that must be cleaned, these contaminants are water-based, such as dirt, dust and bird droppings’ These can be removed easily with a good washing with soap and warm water’ And then there are contaminants on the basis of solvent, including wax, resin, plastic, tar oil and grease’ These systems require the use of grease remover’ To verify that the area is clean, rinse with water’ The water should not adhere to this surface, if we add more grease remover’

Before applying the paint of the car you want, you can remove the old paint from the base solvent to remove the color, what makes a good foundation in his body’ You are now ready to use a study on these surfaces’ Use a high quality gun, the application of heat and horizontal scanning vice versa’ Let dry and re-coat sanding and applying a new layer’

Basic technology of paint

Wednesday, June 17th, 2009

painting automotive, technology has made significant progress in recent years, more or less can essentially quality products in 2 categories, thermoset and thermoplastic’

Thermosets – These are products that cure irreversible’ They need a catalyst that causes a chemical reaction product of the creation of a cross’ This should include your Clearcoat, primers, sealants, panelbond, repair of plastic bumpers and bumper materials themselves’

Thermoplastics – These are products that remain soluble after drying’ They are usually 1 component (without hardener) and does not cross privilege’ That can be broken by any solvent that is reduced to’ This includes your background, first component 1 / painting, repair materials, Part 1 (for example, Urethan window / seal)’

What Cross linking?

Crosslinking is a chemical reaction that causes a group of polymers (natural or synthetic materials) to paste a link’ Cross a large molecule that binds to the paint film, which makes it extremely strong and durable’ The relationship depends on the resin (ie, epoxy, polyurethane, polyester) and each route has its advantages and disadvantages’ Here’s a look at some types of resins:

Epoxy – Epoxy forms the stronger bond due to the crosslinking network of individual products’ Epoxy Adhesive offers resistance to corrosion’ The biggest advantage is its epoxy provides strength and durability, drying time is generally slower’ Epoxy resins are easily broken by UV exposure is not ideal for epoxy coating finishes’

Urethane – Urethane is produced by the reaction of di-disocynates and alchols’ That produce a strong cross-linked urethane chain’ Urethane greater flexibility in the types of products can be created’ He is known for its quick drying time’ The use of primers, Clearcoat, substantive, structural adhesives, adhesives for repairing bumper’

Polyester – Polyester is a strong bond with the ester link and can be reinforced with fibers to improve it’ Polyester is higher tend to decrease, but is cheap compared to other resins’ Uses include bodyfillers, fiberglass, and some books’

Procedures vs’ factory finish

For most of the same resins are used only in a different way’ Epoxy can be applied across the electro-deposition rather than spraying’ The products are usually urethane spray and then heat activated’ The products are supplied with the hardener in it and are not designed to turn until they reach a certain temperature, usually around 200 degrees’ There is little difference in the sustainability of such applications’ Floor paint is cooked only in order to activate the production of urethane Clearcoat and more vehicles’
