Fluorocarbon coating crosslinking agent
The normal temperature crosslinked fluorocarbon coating is composed of a two-component coating consisting of 1% fluorocarbon resin and 1 % isocyanate.
For one of the components, the pigment paste of FEVE fluorocarbon resin (varnish) or FEVE fluorocarbon resin (color paint), fluorocarbon paint crosslinking agent fatty acid diisocyanate (HDI >).
For example, HDI or HDT trimer is another component of the cross-linking agent for fluorocarbon coating. Before coating, the two can be made into a normal temperature crosslinking fluorocarbon coating.
Like other types of coating products, fluorocarbon coating is made up of film, zygomaticus, solvent, fluorocarbon paint crosslinking agent and auxiliary agent. Select each component correctly and determine the dosage of each other in the formula. It is the key to make the normal temperature crosslinking fluorocarbon coating.
In FEVE fluorocarbon coating. FEVE fluorocarbon resin as film is the key to determine coating and membrane performance. Monomer type and the same type of fluorine containing star size different, molecular structure, molecular weight and molecular distribution is different, different side chain substituents, etc. Will lead to the physicochemical properties of fluorocarbon coating made of there is a big difference. It is more important to use FEVE fluorocarbon resin when making the paint. It is suggested to evaluate and select FEVE fluorocarbon resin with the following principles in the development and production of normal temperature and low temperature crosslinking fluorocarbon coating.
Fluorocarbon resin has good transparency and light color. Can represent the performance of a complete specifications and test methods. And consistent with each other in the relations between the indicators (such as the manufacturer to provide the product viscosity and the corresponding relation of molecular addresses are consistent with each other).
It has the operation license of hazardous chemicals. It can provide technical specification for chemical safety.

Specific test data for the shipment of the products (for non-standard inspection days). There are guaranteed indicators as the supplier's quality address commitment. With fluorine containing ` FH '. The technical data and is available for sampling at any time. Resin has no harsh volatiles in grinding paint.
The mixture of the polyisocyanate and the IDI trimer of the polyisocyanate is good. We can guarantee steady shipment of L1. The quality of the batch is stable. The performance price is reasonable.
As FEVE fluorocarbon resin coating used in high weatherability, longer-term maintenance free, so the normal temperature of crosslinking FEVE fluorocarbon coating need high weather resistance, light, color retention can good second aliphatic isocyanate vinegar types of crosslinking agent.
At present commonly used two kinds. One kind is six methylene two isocyanate vinegar (HDI), its application in coatings has two forms, one kind is really react with water to make linear structure of isocyanate crosslinking agent - HDI vinegar. ; The other is the HDI trimer, a polyisocyanate, which is polymerized by JIM. The other type is isoflone, which is a kind of fatty diisocyanate which is saturated cyclohexyl.
The rate of chemical reaction from a physical and chemical perspective can be expressed by the Arrhenius formula, which is aexp-ea/RT (exponential). As the rate constant, k R for molar gas constant, T for thermodynamic temperature, Ea as the apparent activation energy, A is refers to the former factor (also called frequency factor), is also commonly used another form: LNK = lnA - Ea/RT (log).
In order to improve the reaction rate of low temperature crosslinking, it can be analyzed from its chemical reaction mechanism. It can be seen that Ea is a very important factor for the apparent activation energy, which is the minimum energy required by the reactants to reach the activated molecule in the chemical reaction. The chemical reaction rate is closely related to the size of the activation energy, the lower the activation energy, the faster the reaction rate, so the reduction of activation energy can effectively promote the reaction.
