    Notes: Batch production of urea-formaldehyde resins at temperatures up to 100°C takes several hours for completion. Reduction of the batch time may be possible with the higher reaction rates obtained at higher temperatures and increased pressures. In order to investigate this possibility, an experimental technique to obtain the necessary kinetic data, without loss of formaldehyde by evaporation, was developed. The results are compared with earlier low-temperature data extrapolated to the present range of interest. The results were interpreted on the basis of the successive reaction of two or three molecules of formaldehyde with a molecule of urea.

    Notes: Melamine orthophosphate crystals vary in shape and formula according to their method of production. The types vary widely in their behaviour when incorporated into an epoxy resin intumescent coating for trials in a small scale fire test. Heat treatment of melamine phosphate crystals at 210 °C, a process designed to reduce their solubility, profoundly affects the performance of any crystal type in a fire test. In such cases crystal shape alone appears to determine performance, whereas the shape, formula, and state of agglomeration affect performance in coatings produced with untreated melamine phosphate. Small plates of side 20 μm heat treated at 210 °C, are the preferred type for optimum performance and weathering characteristics.

    Notes: A fire test device suitable for small-scale, comparative testing as a first step in investigating the performance of fire retardant materials is described. The procedure developed is not intended to predict the performance of a given material in a real fire, since the local conditions can be extremely variable. However, the parameters in the device can be varied over a wide range to screen the performance of various materials in given situation. Typical results for an intumescent mastic consisting of epoxy resin, hardener and melamine phosphate are quoted, together with appropriate calibration curves. A method of estimating the thermal resistance of the developing char is also discussed.
