|
| HIGH DENSITY POLYETHYLENE |
Highly resistant to pesticides, acids such as used in sanitizing solutions, alcohol and petroleum napthas. Moderate resistance to softening by concentrated oils such as diesel and heavy aromatic solvents used in metal cleaning and cement cutting operations. |
Cannot rust. |
Not affected. Hudson polyethylene sprayers are protected with inhibitors so ultra-violet rays and ozone won't cause cracking and weakening. |
Excellent-can last indefinitely with proper care. Highly resistant to damage from impact. Flexible at normal to low temperatures. Should not be used with high temperature liquids. |
| STAINLESS STEEL |
Completely resistant to commonly used pesticides. Excellent resistance to solutions used in cleaning and maintenance. Can be corroded by extended contact with solutions containing chlorine such as sanitizers. Retains resistance if dented. |
Will not rust. |
Not affected. |
Can last indefinitely with proper care. will not break or crack.
|
| EPOXY-COATED GALVANIZED |
Epoxy coat is completely resistant to commonly used pesticides and most chemicals used in spray applications. Combined with the zinc coating of galvanized steel, it provides a double resistance to corrosion. |
Will not rust unless both epoxy and zinc coating are broken, exposing the underlying steel. |
Not affected |
Excellent mechanical and thermal shock resistance. Long lasting. |
| GALVANIZED STEEL |
Not attacked by commonly used pesticides. Not recommended for strong acid solutions such as hydrochloric or phosphoric acids used for cleaning or sanitizing. |
Will not rust unless zinc coating is broken, exposing underlying steel. |
Not affected. |
Excellent when properly cared for. Zinc coating flexes with stress. |
| EPOXY-COATED PLAIN ROLLED STEEL. (Not used for Hudson Sprayers.) |
If coat fractures, peels or chips, the bare unprotected rolled steel underneath will corrode or rust rapidly. Plain rolled steel is not rust-resistant. Possible to rust even when epoxy-coated. |
Rusts rapidly if epoxy coat is fractured.. even if only a tiny area is exposed. |
Not affected. |
Durable only as long as epoxy coat remains perfectly intact. |
