What is PVC dip?
Dip molding is a process used to create a layer of plastic, usually polyvinyl chloride (PVC), over a metal object. Whether it’s steel, iron, copper, brass or aluminum, metal has different properties than plastic. Unlike plastic, for example, must metal corrodes when exposed to moisture.
How are plastisol coatings applied?
Essentially, the coating process involves the transfer of heat from the metal to the liquid plastisol, which forms a gel on the metal surface. This very weak, soft material then must be cured in a hot oven to fuse the resin particles in the liquid dispersion to form a tough coating on the metal part.
What plastic is used for dip coating?
Plastisol: Plastisol is the most commonly used polymer in dip molding and dip coating processes. It is composed of fine polyvinyl chloride (PVC) resins suspended in a liquid plasticizer. When exposed to heat, it solidifies into a soft, flexible, and rubber-like material upon cooling.
What is PVC plastisol coating?
Plastisol is a PVC-type coating in plasticizing liquids. At room temperature, Plastisol is a liquid; when heated or cured, the liquid turns to a flexible, rubber-like barrier. Once applied, Plastisol coating is practically indestructible, making it ideal for numerous high-impact applications.
What is PVC plastisol?
Plastisols are solutions of PVC or Acrylic polymers dispersed with plasticisers, which are modified with other materials and additives to achieve a range of flexible PVC or Acrylic products.
What is a plastisol coating?
Plastisol is a mixture of a polymer, usually polyvinyl chloride (PVC) and a plasticizing compound (adding stretchiness) which can be used as a coating or poured into molds.
What is plastisol paint?
What is PVC Plastisol?
What is dip coating method?
Dip coating is a simple, low-cost, reliable and reproducible method which involves the deposition of a wet liquid film by immersion of the substrate into a solution containing hydrolysable metal compounds (or readily formed particles) and its withdrawal at constant speed into an atmosphere containing water vapor.
Is plastisol a rubber?
Since it is originally a liquid at room temperature, plastisol is considered a thermoplastic liquid polymer. When in its liquid form, it can be poured into a mold.
What is plastisol molding?
Plastisol dip molding a process whereby a dipping mandrel is dipped into a liquid polymer, typically plastisol, to eventually create a solid form on the mandrel’s external surface. The cost of molding by dipping is always low. Most molds are very simple and inexpensive.
Is plastisol an epoxy?
What is Plastisol? Plastisol is a tough vinyl coating with good insulation properties but at a lower operating temperature. Plastisol is suitable for lower voltage applications and is less costly than epoxy coatings.
What things are made from plastisol?
Common Uses for Plastisol Include:
- Screen printing for t-shirts.
- Medical product development (nasal cannulas, endotracheal tubes, etc.)
- Molded grips for the handles of pliers and other tools.
- Toy parts.
- Baby spoons.
- Plumbing and electrical fittings.
Why is plastic dip coating used?
Plastic Dip Coating is a process that involves immersing a preheated part into liquid Plastisol to form a plastic coating that can add protection and aesthetics to most metal parts. The procedure can enhance the appearance of the part, provide a soft grip, or protect the part from chemicals and abrasion.
How do you remove plastisol coating?
Once the curing process is completed the Plastisol permanently adheres to the component. In fact, the only way to remove Plastisol is incineration at plus 800 degrees! After several hours, this intense temperature breaks down the hardened top of the coating and the remainder is then removed using shot blast.
Can plastisol be painted?
A new paint will add weatherproofing and waterproofing protection to it and the building structure it houses. Painted Plastisol lasts 10-15 years longer than untreated or un-coated cladding. Plastisol cladding can be spray painted and ‘re-branded’ very easily.
