Epoxy resin coatings latent sexual intercourse agent

Epoxy resin coatings latent sexual intercourse agent,Lewis acid - amine complex compound is a kind of effective latent sexual intercourse agent of epoxy resin, composed of BF3, AlCl3, ZnCl2, PF3 lewis acid with primary amine or secondary amine to form complex.

As the crosslinking agent of epoxy resin, this kind of complex is very stable under normal temperature, and at 120 ℃ is fast crosslinked epoxy resin, is one of the most studied boron trifluoride - amine complex compound.

Microcapsule type latent epoxy resin agent intercourse is, in fact, using physical methods bicomponent crosslinking agent at room temperature using fine droplets membrane package, crosslinking agent of the formed microcapsules cross-linking reactivity temporarily closed up, by heat and pressure conditions that capsule rupture, releasing the crosslinking agent, so that the epoxy resin crosslinking.
Microcapsule type latent epoxy resin intercourse of film-former including cellulose, gelatin and poly (vinyl alcohol), polyester, etc, due to the strict preparation technology, the thickness of capsule membrane for storage, transportation and use will bring different degree of influence.

Ir is a kind of high energy density of radiation heating technology, infrared wavelength according to its different is usually divided into near infrared (0.75 ~ 2.0 microns), infrared (2.0 ~ 4.0 microns) and far infrared ray (4.0 ~ 1000 microns). Near infrared, middle infrared can make coating, the coating both heating and infrared radiation crosslinking or actual thermal crosslinking, is produced by using infrared thermal energy to achieve the energy for the crosslinking reaction.

Red diplomacy is characterized by warming faster, at the same time, the energy can be concentrated in the surface coating, so high efficiency. Hot blast stove with general than, can use lower crosslinking effect of crosslinking temperature up to the same. At present in middle density fiberboard (MDF) foreign league of powder coating has been successfully used red. MDF is thermosensitive base material, heating speed, so as to solve the problems of base material is not easy to overheating, and base material internal strength from loss, save time and space.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


UV irradiation crosslinking powder coating (hereinafter referred to as UV crosslinking powder coating) is a traditional powder coatings and UV crosslinking technology with the combination of new technology, UV crosslinking powder coating light crosslinking mechanism of free radical polymerization and cationic polymerization, both have their advantages and disadvantages.

Free radical polymerization has the advantage of water system to shine and oxidization crosslinking speed, the disadvantage is that crumple and oxygen reaction has obviously polymerization; The advantage of cationic polymerization reaction is crumple mild and anaerobic polymerization phenomenon, the disadvantage is that the water polymerization reaction for slow growth, crosslinking time and molecular weight.

The normal use of temperature and humidity: paint temperature in 15 to 35 ℃, relative humidity is not more than 80%, more than the temperature and humidity limits, will consult our technical department before use, paint film construction temperature is too low will make slow dry or not, at this point if forced construction paint, will result in the crack of the late finish; Paint construction temperature is exorbitant, can cause problems such as flow, loss of light, sparkling; The construction environment humidity is too high, to cause a decline in film pale, hardness.

All the oil deep storage time: after the PU paint by formula of blend ratio, the use of no more than 6 hours at room temperature (25 ℃), the storage time is too long paint, after construction will cause poor film flow flat, dry film table then the phenomenon such as particles.
Waterborne paint is a major measure for environmental protection and energy saving carbon reduction. Water-based coatings, including waterborne wood paint with water as dispersion medium and paint thinner. Different from common solvent-based coating, the formulation system is a more complicated system.

Formula design, not only to focus on the type of polymer, the performance of the emulsion and dispersion. Also need to choose all kinds of additives and considering the interactions between various components reasonable matching, sometimes according to special requirements to choose some special additives, eventually forming the applicable formula.
