This article, supplied by Ciba Specialty Chemicals, Performance Polymers, East Lansing, Mich., describes how their Araldite epoxy systems(*) are specially designed to bond SMC substrates. The systems produce longlasting, sag-resistant joints that can withstand exposure to environmental extremes and the vibration to which trucks, buses and other mass transit vehicles are exposed. The adhesives are also easy to use because they are supplied in 200 ml cartridges that provide for precise mixing and easy, low-waste application using Liquid Control's Supermix II cartridge dispensing system.

Identifying non-compliant vehicle repair basecoats / Ellen Daniels in EUROPEAN COATINGS JOURNAL (ECJ), N° 10 (10/2016)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 10 (10/2016) . - p. 30-31 Titre : Identifying non-compliant vehicle repair basecoats : As the trade association representing the vehicle refinish (VR) paint manufacturers in the UK, the British Coatings Federation (BCF) is compaigning to combat illegal sales of non-compliant solvent-based basecoats to repair cars, which are in breach of the VOC regulations Type de document : texte imprimé Auteurs : Ellen Daniels, Auteur Année de publication : 2016 Article en page(s) : p. 30-31 Langues : Anglais (eng) Catégories : Automobiles -- Revêtements:Automobiles -- Peinture Carrosseries -- Entretien et réparations Couche de base Peinture -- Industrie -- Législation -- Pays de l'Union européenne Revêtement en phase solvant Revêtements -- Entretien et réparations Index. décimale : 667.9 Revêtements et enduits Résumé : The BCF's Vehicle Refinish Coatings members must comply with the EU's VOC Paint Product Directive, which has now been in place for 10 years. This limits the amount of Volatile Organic Compounds (VOCs) in paints, which means that paints with high VOC content, such as solvent-based base-coats, should be limited in where they are sold, yet non-compliance in the VR sector is widespread, with an estimated 30% of basecoats sold in the UK for car repair still being solvent-based.

They are applied on larger, painted body components and can be classified in accordance with Diagram 1 in respect of their polishing, paint conditioning and cleaning properties in a product group triangle. The considered product groups differ in terms of these properties. The boundaries between the product groups are fluid in accordance with the representation in Diagram 1 and are partly only determined by the application concentration of certain ingredients. According to Table 1, the following typical ingredients and assessment criteria can be assigned to the three properties or corners of the product group triangle in Diagram 1. The paint surfaces are usually two-component paint systems which are used in the automotive industry. The products are applied as a rule with an application medium (e.g. sponge, cloth). The paint surfaces are heavily exposed to daily strains and soiling and are usually cleaned prior to the application of the above-mentioned three product groups (paint cleaner, paint conditioner, paint polish) e.g. by a car wash (car shampoo). The three product groups (paint cleaner, paint conditioner, paint polish) are as a rule used for value preservation and optical upgrading of the paint surfaces and differ in terms of composition of the ingredients and proper use. The products are commercially available in bottles, tubes or glass jars, tin cans or plastics boxes or other containers as well as in other presentations. They are available in a liquid, solid or pasty condition.

The application properties viz. ease of application ; flow, leveling, sagging, etc and shelf stability of the putty fillers are governed by its rheology. In the present study, application properties and shelf stability of six putty samples (premium, economic, and low cost grade) were studied using rheometer. Flow curve, three interval thixotrophic test (3ITT), oscillatory amplitude sweep and frequency sweep tests were carried out. Yield point and high shear viscosity was correlated with ease of application. Viscosity after recovery and loss factor (Tan ?) was correlated with flow, leveling, sagging and shelf life of the putty fillers. Above results were finally compared with actual application of putty fillers on metal substrate.
