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’
