Colour is an excellent way of personalising your home, helping your company's brand stand out or expressing how you Peel.
High public demand for colour has been confirmed by market research on pigments, which show not only an increase in demand for colour but also the considerable potential for a wide range of hues, as a resuit of the colour solutions available.
One of the rnost common ways of incorporating organic and inorganic pigments into paint is dispersion in liquid. The pigment or pigment paste to be used must be chosen carefully and accurately on the basis of the context in which it is to be used.
When exterior colour is called for (so-called façade paints) the choice of pigment is crucial to the development of tinting systems because it is necessary to guarantee the paint's performance when it is exposed to environmental conditions, such as rain, sun, heat and cold.
Tinting system development hinges on the need to encompass the greatest range of colours in the widest variety of available paints and products (acrylic and alkyl paints, etc) including mineral paints (silicate and silicone-based) and external thermal insulation systems (External Thermal Insulation Composite Systems, ETICS).
Clearly the challenge is in obtaining the widest range of colours possible, whilst maintaining high performance standards for exterior
In this article I will attempt to analyse the delicate equilibrium, which exists between the chemical make-up and the structure of inorganic pigments, their colour hues, their pigmentation capacity and their performance when exposed to the sort of atmospheric conditions and aggressive environments characteristic of outdoor surfaces.Note de contenu : - Exterior paints

Titre : Transportation of polymerising substances Type de document : texte imprimé Auteurs : Filippo Busolo, Auteur Année de publication : 2017 Article en page(s) : p. 29-30 Langues : Anglais (eng) Catégories : Polymères

With this new type of dangerous goods, the concept of self-accelerating polymerisation temperature (SAPT) has been introduced, meaning the lowest temperature at which the polymerisation of a substance may occur in the packaging, IBC or tank as delivered for transport. The SAPT shall be determined in accordance with the test procedures established for the self-accelerating decomposition temperature (SADT) for self-reactive substances in accordance with Part II, section 28 of the Manual of Tests and Criteria.
Without stabilisation, polymerising substances are liable to undergo an intense exothermic reaction resulting in the formation of larger molecules or polymers under normal conditions of transportation.
Such substances belong to the category of easily polymerising substances of class 4.1 when:
a) Their self-accelerating polymerisation temperature (SAPT) is 75°C or less under standard conditions (with or without chemical stabilisation as delivered for transport) or in the packaging, IBC or tank in which the substance or mixture is to be carried;
b) They have a heat reaction of more than 300 J/g; and
c) They do not meet any other criteria for inclusion in classes from 1 to 8.
A mixture that meets the criteria of a polymerising substance must be classified as a polymerising substance of class 4.1.
Polymerising substances are subject to temperature control during transportation if their self-accelerating polymerisation temperature (SAPT) is:
a) When delivered for transport in a packaging or IBC, 50°C or less in the packaging or IBC in which the substance is to be carried; or
b) When delivered for transport in a tank, 45°C or less in the tank in which the substance is to be carried.
These substances are classified according to the following categorisation codes - PM (polymerising substances), PM1 (not requiring temperature control) and PM2 (requiring temperature control). These codes belong to packaging group III. List of entries:
1. UN 3531 Polymerising Substance, Solid, Stabilized, N.O.S.
2. UN 3532 Polymerising Substance, Liquid, Stabilized, N.O.S.
3. UN 3533 Polymerising Substance, Solid, Temperature Controlled, N.O.S.
4. UN 3534 Polymerising Substance, Liquid, Temperature Controlled, N.O.S.
Further details on the goods’ properties are included in the new IMDG Regulations, amendment 38-16. UN 3531 and UN 3532 report that these substances polymerise at high temperatures or in a fire, burning vigorously.
They are insoluble in water and, on contact with alkalis or acids, they may cause dangerous polymerisation. The products of combustion or self-accelerating polymerisation may be toxic if inhaled. In the case of UN 3533 and UN 3534, the goods polymerise at higher temperatures than the SAPT or in a fire. These goods are insoluble in water and, on contact with alkalis or acids, may cause dangerous polymerisation. The products of combustion or self-accelerating polymerisation may be toxic if inhaled. Control and emergency temperatures can be found in the bill of lading, as required by IMDG regulation 5.4.1.5.2. Temperatures must be checked regularly.
The new special provision number 386 applies to the newly introduced four sections. The conditions for the stabilisation of substances and for the regulation of temperature are defined in this provision.Note de contenu : - Packaging and tanks
