| Volan |
 |
| Werner-type chromium complexes of methacrylic acid in isopropanol. |
 |
Volan bonding agents are formulated solutions containing unique surface-complexing monomers of chromium(III) methacrylate. During application, the active molecules attach to inoraganic or polar substrate surfaces and orient themselves with polymerizable groups outward, to permit combination with a wide variety of thermosetting resins : - Polyester , - Epoxy , - Phenolic , - Vinyl , - Acrylic , - Polyvinyl Acetate.
The ability of Volan to attach securely to inorganic or polar surfaces allows it to develop tenacious bonds to substrates such as : - Glass , - Metals , - Polymers , - Silica , - Boron , Natural fibers
By far the most important use for Volan is as a finish for glass fiber roving, which is then used as the reinforcement agent in unsaturated polyester resins. Volan is a key component of the “chrome” size, which is applied by padding on strands at the bushings during glass fiber manufacture. The effectiveness of Volan with standard polyvinyl acetate binders is related to its compatibility with the emulsion stabilizer system used in the polyvinyl acetate.
Volan also serves as an anti-static agent. Chopped strands and rovings sized by treatment with Volan combine rapid wetting and good laminate strengths with ease of cutting and low static charge. Processors recognize all these properties as vital to trouble-free processing, particularly with gun rovings. |
