Do you know what lies behind the beauty and long life of all the decorative objects around us? Vibrant and long lasting hues are engineered. It is the use of inorganic and organic pigments for paints and coatings that have helped to display articles in their best light and endure the harshest demands.
Industrial applications of paints and coatings are wide and varied including the likes of aerospace, coil, automotive, refinishing, household and architectural industry and many more. It is therefore essential for all paint formulations to meet numerous criteria. Technical specifications, durability, opacity, ease of application are just to name a few of them. Pigment powder preparations have to possess key attributes that will help to cope with the increasing demands of industry. Some attributes that the paint industry focuses on are colour strength, durability, coverage, light and weather fastness, chemical inertness and excellent environmental performance. In case of metal applications, special emphasis has to be given to the anti-corrosive factor and pigments that fulfil this requirement are needed for automotive, direct-to-metal or industrial coatings.
Rust should never be given a tiniest chance to thrive in any paint application. Corrosion devastates loads of steel every single moment and the costs that have to be paid for this run in millions of dollars world- wide. Using anti-corrosive pigments that are eco-friendly and sustainable is of paramount importance. These solutions enhance metal life and decrease costs over the long term. Moreover, with greater emphasis being placed on eco-friendly pigments, efforts are concentrated on offering substitutes to carcinogenic anti-corrosive pigments that are chrome based. Focus is on pushing polyphosphate, orthophosphate, organic inhibitor, broad-range anti corrosives as well as zinc free anti corrosive pigment items for paint formulations. Corrosion protection pigments that are calcium modified silica based are setting standards in the paint formulations.
Pigments are elements that lend colour to paints and hold a special place of importance in the paint industry. The paint industry uses from a wide range of pigments for paint including some speciality pigments. Application of paints can be broadly categorized into two classes and they are colorants for decorative/architectural applications or the industrial applications. One class of pigments that display good tinctorial features coupled with reasonably good fastness to light, heat and solvents are the naphthol reds which are used in latex emulsions and masonry paints. Today, however, regulatory, ecological factors as well as economic considerations are increasingly affecting the composition of paint formulations. This has led to the development of innovative techniques that fulfil the rigorous demands placed on the paint industry. In order to incorporate eco-friendly, zinc-free pigments into paint formulations following requirements have to be met:
- Excellent dispersion properties
- Universal application
- Stability
- Cost effectiveness
- Excellent anodic corrosion safeguard in water and solvent based systems
Emphasis is therefore placed on obtaining solutions that meet all demands placed from every front on the paint and coating industry.
Identifying the most suitable corrosion protection pigments for your coating and paint applications can be quite a challenging task; however, liaising with the technical experts in the field will enable you to get the right solution. Just choose a reputed company and your costs will yield attractive colors.
