How to improve the leveling of powder coatings?

How to improve the leveling of powder coatings? Powder coating is a new type of solvent-free 100% solid powder coating. It has two major categories: thermoplastic powder coatings and thermosetting powder coatings. The coatings are made of resin, color filler, curing agent and other additives, mixed in a certain ratio, and then prepared by the process of hot extrusion and crushing through the sieve. They are at room temperature, storage stability, by electrostatic spraying or fl

Why epoxy paint is not suitable for outdoor use

Epoxy paint is widely used in heavy anti-corrosion because of its extremely strong adhesion; excellent mechanical properties, wear resistance, impact resistance; excellent corrosion resistance, impermeability; high storage stability, long shelf life, etc. However, the biggest drawback of epoxy paint is that it has poor weather resistance and is easy to age. It can only be used as primer or indoor paint, and is generally not suitable for outdoor use. Epoxy paint (epoxy res

The main factors affecting the electrostatic powder coating

The main factors affecting the electrostatic powder coating There are many factors that affect electrostatic powder coating, such as: equipment factors, operating factors, etc.. But the main factors are powder conductivity, powder particle size, spraying voltage, spraying distance (between the gun and the workpiece), air supply pressure, etc. 1, powder conductivity: the volume of powder particles must be moderate, volume resistance is too large, the powder ch

In the powder coating powder curing bad reasons

Considering from powder coating, if the matching of resin and curing agent in the formulation design is not reasonable, such as the choice of reactivity of resin or the species and dosage of curing agent is not reasonable; the mass percentage content of filler or volume concentration is too large, etc. These problems will affect the physical and mechanical properties of the coating film. Considering from the powder coating process, the reas

TGIC Powder Coatings vs. Non-TGIC Powder Coatings

TGIC Powder Coatings vs. Non-TGIC Powder Coatings As raw materials become increasingly scarce, powder coating consultant Rodger Talbert offers insights into using non-TGIC products. Q: Since we began powder coating around 15 years ago we have gravitated to more TGIC Powder for our outdoor product. The results have been reliable and performance has been excellent. We get good sun-light resistance and chemical resistance and very few problems with surface blemishes. Lately, our supplie

Are TGIC-Free Powder Coatings Right For You

Are TGIC-Free Powder Coatings Right For You Durability and weather-resistance are non-negotiable requirements when specifying powder coatings for applications such as heavy equipment, agricultural vehicles, outdoor lighting and architectural products, playground equipment, and recreational goods. For years, triglicydyl isocyanurate crosslinkers (TGICs) have been employed in exterior, polyester-based powder coating applications to provide those required characteristics. TGIC cr

What should be paid attention to when the powder coating equipment is operated in the powder sprayin

Powder spraying is a key process in the spraying production process when working in the spray booth. The key to the surface quality of the sprayed workpiece lies in the control of various process parameters during the spraying process. Powder output and atomizing air are two key technical indicators. Before the formal powder spraying, you can try spraying several times. At this time, you can observe the size of the powder amount and the uniformity of the powder distribution at both en

Which factors are related to the excessive surface particles during the powder spraying process of a

In the process of powder spraying of aluminum profiles, a common problem that makes powder spraying technicians feel headache is the protruding particles-particles on the surface of the powder coating coating. The particles seriously affect the decorativeness of the surface coating of the aluminum profile. Regarding which factors are related to the excessive surface particles during the powder spraying process of aluminum profiles, let's take a look together. 1. Processing of co

What are the precautions for valves in electrostatic spraying?

A valve is a device used to control the direction, pressure, and flow rate of a fluid in a fluid system. It is a device that allows the medium (liquid, gas, powder) in piping and equipment to flow or stop and can control its flow. The valve product market, especially pneumatic valves, is developing in the direction of high technology content, high parameters, and strong corrosion resistance. This development direction also puts forward higher requirements for the coating of valves. Electrosta
