High solids systems

Fig. 3. RSST results on some typical production novolacs. The solids on these materials are 74, 70, and 62%, respectively. Note that the reaction does not become initiated significantly below 70 C and that the high solids system is capable of self-heating rates as high as 5500°C/min under these conditions.

The main advantage for using hyperbranched structures may rest in their rheology (film formation from high-solids systems) and in some cases added value in properties (hardness), but deeper knowledge should be accumulated before a more comprehensive evaluation can be made. [Pg.142]

But, in the general case, inhomogeneities are induced by fast chemical reactions and are very difficult to control. For this reason, precursors of controlled architectures have been developed for different purposes, such as to decrease the viscosity in high-solids systems, to lower shrinkage, to improve material properties and, for some electronic and nonlinear optical applications, to build nanosized ordered regions in the networks. [Pg.234]

Table II also rates the properties of amidoamines and cycloaliphatic amines. None of these curing agents appear to satisfy all of the desired properties. There are clearly some unfulfilled needs here however, the particular combination of properties of the presently commercial phenalkamines comes closest to satisfying the requirements. They are quite suitable for high solids systems. Table II also rates the properties of amidoamines and cycloaliphatic amines.

Modern coatings continue to be developed in response to both economical and ecological pressures. Two promising routes are via aqueous solution/dispersion systems using polymers with carboxyl functionality temporarily neutralized by amines and via high-solids systems where small reactive molecules are applied in high concentrations. [Pg.750]

Table VII distributes automotive topcoat usage by type, with predictions for 1987. The progression from low-solids, high-emission coatings to high-solids systems is shown. Research and development of HS-E are active at each of the auto companies and at every major coatings supplier and raw materials producer. Certainly, problems such as specific polymer design and cross-linker choice still exist—as well as application, flow, and aluminum flake orientation. However, current and future research and development should reduce these problems rapidly to manageable levels. Table VII distributes automotive topcoat usage by type, with predictions for 1987.

Epoxy paints (see also Section 2.10) are usually applied as two-pack systems. Curing with amines is preferred in high-solids systems. Epoxy resins may also be used as coreactants or reactive diluents in low-solvent paints based on acrylic, polyester, or alkyd resins. [Pg.108]
