Euroceras PE wax for cast film masterbatch

2021-12-22   Pageview:249

Customer area: cast film masterbatch

Industry problem: As the processing temperature of cast film reaches 240-250 degrees, the materials used (pigments and dispersion aids) should be subject to high temperature resistance, no scorching, no discoloration, stable color, no precipitation, high surface finish, and less material accumulation at the mold mouth.

Solution: High temperature resistance, heat loss of 2T is only 1% at 250 degrees, high wetting and high dispersion of pigment, which is very helpful to improve surface finish, and very little accumulation of material at the mold mouth, so it is not easy to produce defective products.

 

 

 

 

 

 

 

 

 

 

 

 

 

Most of the construction (painting) methods of thermosetting powder coatings use electrostatic powder spraying, and a small number of them use vacuum suction (decompression suction), air spraying, flame spraying, fluidized bed dipping and electrostatic fluidized bed dipping, etc. Construction (painting). The following are epoxy powder coatings, epoxy-polyester powder coatings, polyester powder coatings, polyurethane powder coatings, acrylic powder coatings, fluororesin powder coatings, UV curing powder coatings and special powder coatings [including electrophoresis, water dispersion (thick Paste), antibacterial and insulating powder coatings], etc. will be introduced in detail.

Epoxy powder coatings are thermosetting powder coatings developed in the 1960s. For a considerable period of time, epoxy powder coatings have become the most versatile and widely used thermosetting powder coatings. However, since the late 1980s, with the rapid development of epoxy-polyester powder coatings, this powder coating has advantages over epoxy powder coatings in terms of decoration and price. Many uses of epoxy powder coatings have gradually changed from epoxy powder coatings. -Replaced by polyester powder coatings, epoxy powder coatings have changed from a primary position to a secondary position. According to pe wax honeywell statistics in 2006, epoxy powder coatings accounted for 6.5% of the world’s output of thermosetting powder coatings, and its output ranked third behind epoxy-polyester and polyester powder coatings.

There are many types of epoxy powder coatings, which can be divided into decorative type, anti-corrosion type, electrical insulation type, etc. Artistic powder coatings with uneven appearance can be divided into patterns, wrinkles (orange patterns), sand patterns, hammer patterns, metallic flashes, etc.

Epoxy powder coatings are thermosetting powder coatings composed of epoxy resin, chemical agents, pigments, fillers and additives. Bad powder coatings are generally manufactured by the most commonly used melt-extrusion mixing method in the powder coating manufacturing method. This method is to pre-mix all raw materials uniformly with a high-speed mixer, then use an extruder for melt extrusion mixing, then cool and crush; then use an air classifying mill for fine pulverization. Then use a cyclone separator to classify, and finally use a sieve The product is sieved and separated by the separator.
