ADHESIVES FOR URETHANE

ADHESIVES for URETHANE URETHANE is ethyl carbamate, one of a group of organic compounds sharing a common functional group with the general structure (-NH(CO)O-). Carbamates are esters of carbamic acid, NH2COOH, an unstable compound. Since carbamic acid contains a nitrogen attached to a carboxyl group, it is also an amide. Therefore, carbamate esters may have alkyl or aryl groups substituted on the nitrogen, or the amide function. Urethane or ethyl carbamate, is unsubstituted, while ethyl N–methylcarbamate has a methyl group attached to the nitrogen. Urethane should not be confused with polyurethane which is not made from carbamic acid at all. Urethane is available in many different chemical formulae (due to additives), giving it different chemical properties, and in varying thicknesses -- both of which affect its coefficient of expansion. Urethanes can generally be classified into four groups, thermoplastic urethanes, urethane rubber, urethane as a coating and urethane adhesives all of which have differing uses and physical properties. Successful long term bonding of urethane to itself, and to other substrates, requires careful preparation and matching of the adhesive being used with the differing COEs of the substrates involved. BONDiT TM products are among the few available that can be used to bond urethanes to substrates with differing COE's for harsh environments and long term deployment without debonding.

Chevy Front/Rear Anti-Sway Bar Set, With Urethane Bushings, All Except Wagon, 1955-1957

Dramatically Reduces Body Roll Quite simply, the single largest handling improvement you can make - anti-sway bars for your classic! These high-quality anti-sway bar kits are easy to install and feature heavy-duty solid steel 7/8" powder coated bars. All urethane bushings, installation hardware and instructions are included. While dramatically improving driving performance by reducing body roll and sway, the addition of anti-sway bars will not reduce your comfy ride quality. These bars will clear disc brake kits, rear traction and shock bars as well. With the addition of a set of radial tires and our anti-sway bars, you'll think you are driving a Corvette instead of a classic Chevy! This set fits all except station wagon. Wagon/Delivery/Nomad owners should order P/N 21-251.

Acrylic Urethane Coating

Endcor 4600 brochure (PDF) Endcor 4600 series coatings are two-package, glossy, high-performance coating systems based on a chemically cross-linked combination of acrylic and polyurethane polymers. They exhibit outstanding toughness and durability, chemicals and weather resistance, gloss and color retention. They are resistant to chalking and yellowing, and provide a hard surface with excellent resistance to impact and abrasion and to surface dirt pickup and staining from lubricants, fuels, solvents and detergents. Endcor 4600 series coatings provide an unusual combination of cost effective, long-term, heavy-duty protection, maximum durability and an attractive appearance for metal and concrete surfaces exposed to corrosive chemical, industrial and marine environments.
