RATCO offers the following options for Frame finishes.


EXTERIOR FINISHES:

Electrostatic Powder Coating - our preferred finish due to it's durable surface which looks like a plastic coating and provides a distinctive finished look.  We have found this surface finish to be far superior to any painted finish.  This polyester powder coating material can be repaired easily and will not pull back significantly if welding is necessary. We have found that it can be spread with a trowel when it is hot and blended easily. To make the repair look natural, feather the area when cool with sandpaper and paint with Krylons new fusion paint which is made to paint plastic.  It provides a polyester coating just like the type of powdercoat we use . Our new awareness of the qualities of this powder coat and the fact that paint and powder coat now cost about the same, has led us to drop paint from our options list. Powder coating includes sandblasting, sanding, powder primer coat and a powder finish coat in a variety of colors. Black is the most popular, but a variety of other colors are available.

Un-Finished - Frames that our customers would rather finish themselves are sprayed with a metal prep solution to keep the frame from surface rusting until it is sandblasted and finished. Many people like to use the POR-15 system.


INTERIOR FINISHES:

Expanding Foam - Our Preferred choice is relatively new to the market and that is the application of expanding foam to all the interior areas of the frame. This foam is water proof and sticks like glue to all surfaces. The application is once again through holes drilled in the tubing. The expanding foam is forced into one end of the tube length and allowed to ooze out of the other end to assure a complete fill. Once dry the over fill is cut away and the holes are filled with plastic plugs. This foam application does two things to the structure. First it makes for an impenetrable water seal and secondly sound dampens the frame. You may think this a minor point but in fact the frame does resonate and amplify the vibrations caused by road conditions and those passed along by the drive train. Foam filling quiets the ride appreciably. About 85% of all the frames made to date are foam filled.

Traditional paraffin based coating - Coats the interior surface of the tube with a waxy substance much the same as undercoating that seals the metal from exposure to oxygen and moisture. This material is applied through holes drilled in the frame members at strategic locations and then sprayed in to the openings to coat the interior surfaces. All the holes drilled are then closed with plastic plugs that are then part of the frame and can be painted over to seal the mating line.


Either method of rust proofing will assure a rust free interior surface for the life of the frame.
