*This webpage generally introduces HAKKO products for inks, paints and solvents. If you look for a hose for automotive/motorcycle manual painting line, we have another webpage. Please visit this page.
Introduction
Paint is usually the mixture of resin, hardener, pigment, additives and solvents. The combination ratio (and of course, the contents of these five fluids) differs from paint to paint, so various kinds of paint are sold in the market. This is partly because of the diverse painting objects. The example of the painting objects is metallic components, plastic parts, airplane and furniture, just to name a few. In order to safely transfer various kinds of paint, various types of paint hose are required.
For Solvent-Based Paints: Solvent Transfer Hose
Solvent-Based paints usually include Amino Alkyd Resin, Acrylic Resin, Urethane Resin and Epoxy Resin. For transferring solvent-based paints we recommend a hose made of polyamide (nylon).
Due to the growing concerns of workplace safety, more and more factories require the measurements against static electricity. HAKKO "Solvent Transfer Hose" [E-SV] meets this requirement. With the stainless steel fiber and conductive polyurethane line, HAKKO "Solvent Transfer Hose" [E-SV] can eliminate the static electricity charged to the spray gun. Also, because of the spiral structure of stainless steel fiber and conductive polyurethane line, you do not have to take out the steel fiber. You only need to insert HAKKO original fittings to the hose. (Patented)
*If you are looking for a hose for solvent-based paints and do not need any measurements against the static electricity, "Paint Flex-Nylon Hose" [E-PFN] is the suitable option for you.
For Water-Based Paints: Flexible Fluorine (ETFE) Resin Hose Series
Water-based paints usually include Emulsion Resin and Water-Based Resin Paint. For transferring water-based paints we recommend a hose made of ETFE Fluorine.
As part of measures to reduce volatile organic compounds (VOC) recommended by the Ministry of the Environment, oil-based paints (Paint using a second organic solvent such as toluene or xylene) have gradually changed to water-based paints (water solubility). For nylon hoses, which have proven to have been used in oil-based paints, chemical resistance to alcohols and amines is relatively low. Thus, the durability of nylon hoses for water-based paints is very short.
We recommend "Flexible Fluorine (ETFE) Resin Hose Series," because of their high chemical resistance to alcohols and amines. We have various product lineups under the category of "Flexible Fluorine (ETFE) Resin Hose Series," so hopefully, you will be able to find the best one for your application.
For UV-Curable Paints: Flexible Fluorine (ETFE) Resin Tubing Black
As a hose for transporting UV-curable ink, UV-based paint, UV adhesives and so on, HAKKO ”Flexible Fluorine (ETFE) Resin Tubing Black" [E-SJ-BK] has been widely used by customers all over the world. Although the maximum standard size of E-SJ-BK is I.D. 8mm, we can produce a hose with bigger I.D. size as a made-to-order product. If you need a bigger I.D hose for transferring UV-based paints, please fill out our made-to-order inquiry form.
