Abstract: A method for delivering and processing a formaldehyde-free resin at a facility. The method maintains the resin slurry at a minimum temperature throughout storage of the resin slurry and use of the resin slurry to prepare a binder composition at a make up site. Maintaining the resin slurry at or above a minimum temperature ensures that a minimum viscosity is maintained to permit the proper flow of the resin slurry. The method utilizes external heat sources in conjunction with storage and transport systems to ensure that a minimum temperature is maintained.

Abstract: A system for controlling the pH of the process water used in conjunction with formaldehyde-free binder composition for glass fiber products. A base solution is introduced into the process water used to coat the glass fibers in the formaldehyde-free binder after the water is extracted from binder coated glass fibers when the pH of the process water in less than about 6.0. The addition of the base solution increases the pH of the process water to a range from about 8.0 to about 6.0 thereby reducing the risk of corrosion when the process water is recirculated.

Abstract: A system for controlling the pH of a formaldehyde-free aqueous binder composition used in the manufacture of glass fiber products. Following the formation of an aqueous binder composition, acid is added to the composition to reduce the pH to less than about 3.4. After the acid is combined with the aqueous binder composition, the pH of the composition is measured and then compared within a pre-set set point. The rate of acid addition is then adjusted thereby adjusting the pH of the composition such that the measured pH equals the set point pH. The pH measurement is preferably done before the addition of other additives to avoid interference by those additives.
