Dip Coating Material used: Low density polyethylene and nylon. The items to be coated are preheated between 250-450°c and immersed into a bath of fluidised seal powder for a determined time dependant on the thickness of the coating. The powder melts onto the metal to form a smooth coating. A post heat maybe necessary for the coating to flow out completely. Typical uses:
Electrostatic Spraying (Thermosetting powders - Epoxy/Polyester) The components to be coated are degreased and iron phosphated on line then dried or degassed as required. Components are then sprayed with charged particles of powder which are held onto the components by the electrostatic charge until they are cured (chemically cross-linked) by heating for typically 10-15mins @ 180-200°c. As soon as they are coated the process is complete and you are left with a smooth, even coating. We have a wide range of colours and specialist finishes (i.e. antique, metallic, etc) Typical uses:
Electrostatic Spraying (Thermoplastic powders - PPA/Nylon) The components to be coated follow the same path as thermosetting powder until the final stage where instead of curing nylon or PPA is fused onto the metal by heating for typically 10-15 mins at 200-210°c . As the coating melts it flows onto the metal substrate forming a fine bond. We have a wide range of colours available. PPA is approved to M1 & M2 of UK Building Regulations for handrails, i.e., slip resistant and not cold to the touch. Typical uses:
