DryAdd Online Application Notes


These are the original application notes for DryAdd, done using an early version of the program. They can be read with any viewer which is capable of displaying PDF files (e.g. Adobe Acrobat Reader). Brief descriptions and links are given below.

We also have specific application pages on polyurethanes, urea-formaldehydes, phenolics and epoxies. You can access these by following the links we've given in the preceding sentence.

Additional Application Notes summaries

Improving Polyurethane Foams with DryAdd
DryAdd is used to simulate a system containing the amine forming isocyanate-water reaction - which generates CO2 to give water-blown polyurethane foams. The effect of isocyanate functionality on gelation is also illustrated. View pu-foams.pdf


Improving Epoxy Formulation with DryAdd
The importance of the ratio of amine epoxide groups in epoxy resin formulation is illustrated using a DryAdd simulation. The simulation can be directly compared to published work (K C Cheng and W Y Chui, Macromolecules, 27, 3406 - 3414). View epoxies.pdf
Characterising Coatings Cure with DryAdd
DryAdd is used to simulate the cure of polyurethane clearcoats. The complementary use of polymerisation simulation and conventional techniques such as DMA and DSC is illustrated. View dmacure.pdf
Improving Polyurethane Dispersions with DryAdd
DryAdd's formula analysis capability is used to predict the relative proportions of species in the aqueous phase of polyurethane dispersions. The resulting information is then used to predict which species will be found in the particle cores and which in the aqueous solution. View pu-disp.pdf.
Improving Mechanical Properties with DryAdd
DryAdd 's sequence analysis function is used to determine the lengths of hard and soft blocks, which are important in looking at phase separation in thermoplastic polyurethanes. The effect of varying isocyanate in different ratios on the hard and soft block length is shown. The resulting weight distribution plots agreed with HPLC results. View mechprop.pdf
