Binder with high corrosion resistance

Development of Anionic ED Binders with High Corrosion Resistance... 

The industrial value of furfuryl alcohol is a consequence of its low viscosity, high reactivity, and the outstanding chemical, mechanical, and thermal properties of its polymers, corrosion resistance, nonburning, low smoke emission, and exceUent char formation. The reactivity profile of furfuryl alcohol and resins is such that final curing can take place at ambient temperature with strong acids or at elevated temperature with latent acids. Major markets for furfuryl alcohol resins include the production of cores and molds for casting metals, corrosion-resistant fiber-reinforced plastics (FRPs), binders for refractories and corrosion-resistant cements and mortars. 

An unaccelerated, low viscosity, styrene free, corrosion resistant (to acidic and aikaline environments), flame retardant (<25 ASTM E-84 with 3% antimony trioxide) vinyl ester, offering high strength, excellent impact strength and toughness, designed to bond Hetron FR 992 resin laminates and meet the low odour requirements of the semiconductor and other industries. Since this resin does not contain styrene, the glass reinforcement must exhibit very little binder conventional CSM s do not wet-out well with this resin. 

In order to avoid diffusion in the plgment/binder interface, in-terfaclal bonds between lx>th phases should be as water-resistant as possible. If permeability is taken as a measure, properly formulated barrier coatings may coiipare in corrosion protective efficiency with normal coatings, the thickness of vhlch is tvo or three times as high.
