Generally, coatings for metal protection should be hard, humidity and chemical resistant, have good adhesion and corrosion resistance, and good gloss in pigmented systems. Water-borne acrylic resins used for metal protection are usually high Tg acrylic or styrene/acrylic copolymers. Because of the nature of the binder, addition of coalescents and plasticisers are essential for proper […]

PH adjusters

In most cases, the systems require pH’s in the range 8.0-10.0. If the pH is outside this range, then the stability of the finished product can be seriously affected and viscosities can change quite significantly especially if a pH sensitive thickener is being used. Generally, ammonia or other organic bases are used to control pH […]


These are necessary in most, if not all, formulations if fungal attack in the can and, sometimes, of the dried film is to be avoided. Over the past few years, new products have come onto the market which are far less hazardous than the original materials, many of which were mercury derivatives and were toxic […]

Slip and Mar

Slip and mar are important properties of the finished dried coating and can be significantly improved by the careful use of silicone additives and waxes. The wrong selection can lead to foaming problems. Both silicones and waxes work by preferentially migrating to the surface so that quite small additions can have a marked effect. Significant […]
