Hexaméthoxy méthyl mélamine
MélamineLa mélamine, de nom chimique 1,3,5-triazine-2,4,6-triamine, est parfois dénommée cyanuramide ou cyanurotriamine. Sa formule brute est C3H6N6.
Les "résines mélamine-formaldéhyde" ou "mélamine-formol" (sigle MF) sont appelées "mélamine" dans le langage courant. Elles font partie de la famille des aminoplastes qui regroupe des résines thermodurcissables aminées, issues d'un comonomère tel l'urée ou la mélamine, parfois le thiocarbamide, le cyanamide hydrogène ou le dicyandiamide ; le second comonomère étant le formaldéhyde.

UrethanesIndex. décimale : 667.9 Revêtements et enduits Résumé : New water-soluble urethane diol resins have been developed to be used as resin modifiers for waterborne coatings systems crosslinked with amino resins. These urethane diols are a multipurpose chemical species that can be utilized to enhance performance properties as well as resolve some of the common issues experienced when formulating waterborne systems.
The above-mentioned resin modifiers are water soluble without the presence of amine neutralizers, surfactants, or co-solvents. Incorporating these urethane diols will thus improve the water solubility of a resin system in a wet paint, subsequently reducing the need for neutralizing amines and additionally allowing for easier resin incorporation with less co-solvent requirements. As resin modifiers, the urethane backbone allows formulators to enhance performance of aminoplast crosslinked coatings by incorporating urethane groups into a crosslinked network without the use of an isocyanate.
This work demonstrates the versatility of these urethane diols and further discusses how they can be used to enhance coating performance by improving corrosion and humidity resistance, as well as increasing hardness while maintaining flexibility.Note de contenu : - INTRODUCTION : Waterborne polyester formulations crosslinked with amino resins - Formulating with melamine crosslinkers - Necessity and effects of amine in PE/HMMM coatings - Polyurethane coatings - Urethane linkages in melamine coatings - Pursuit of non-VOC coatings : the rise of aqueous formulations and their limitations - Urethane diols for modifying aqueous formulations crosslinked with amino resins

Vernis en phase aqueuse -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : Liquid ethylene propylene diene rubber (L-EPDM) has been known in the coatings industry for many years. These elastomers have found utility in ambient cure liquid-applied roof coatings. These resins, formulated into waterborne liquid coatings, may be cured with peroxides, metal driers, or UV radiation and can be used in ambient maintenance coatings for flat or low-slope roofs.
Simplified structure of L-EPDMRecently, formulations blending the L-EPDM with other common coatings resins have been developed. Elastomeric acrylics, alkyds and polyurethanes have been blended with the L-EPDM without the use of compatibilizers. Each of these systems has seen unique property improvements, such as surface wetting, adhesion, impact strength, and more.
Additionally, industrial heat-cure formulations have been developed for a broad range of temperatures. This paper will discuss L-EPDM waterborne suspension and blend properties, coating formulation, application and curing methods, and final film properties.Note de contenu : - EXPERIMENTAL : Blending L-EPDM dispersion with other binders - Coating formulation and testing

Tests de toxicitéIndex. décimale : 667.9 Revêtements et enduits Résumé : Microbial contamination on surfaces is a problematic and potentially deadly issue, particularly in high-risk settings such as healthcare, aged care, and food and beverage. In this research, we present an antimicrobial waterborne polyurethane additive that will be of interest to the coatings community due to its high compatibility with a variety of coating systems, which results in a range of highly diverse and useful applications.
This next-generation antimicrobial uses a nanocomposite approach to create a silver-based active ingredient that is non-toxic and truly non-leaching.
The presented technology produces strong binding between silver and the polymer backbone. This prevents leaching while retaining high activity with proven results against a range of pathogens.Note de contenu : - EXPERIMENTAL

Stabilisants (chimie)Index. décimale : 667.9 Revêtements et enduits Résumé : The author discusses the development of Disperbyk-2155, which provides a high molecular weight for stabilisation and solids content.
Due to its innovative sphere-like structure, Disperbyl-2155 combines high molecular weight with high solids content, therefore opening up new horizons in the wetting and dispersing of pigments in high solid as weel as in conventional coating systems. It displays outstanding deflocculation and stabilisation properties, effectively reducing mill base viscosity, is storage-stable and shows wide compatibility with many different types of resin systems. The next generation polyurethane wetting and dispersing additive Disperbyk-2155 is designed to be used in pigment concentrates for automotive coatings, floor coatings (based on polyurethane and epoxy), polyurethane foams and thanks to its 100% solids content also for solvent-free UV systems. In addition, the additive has been successfully used in co-grinding systems.Note de contenu : - Pigment stabilisation in high solid systems
