Many different extrinsic and intrinsic factors such as pollution, increased exposure to chemicals, stress of our hectic lives, hormones etc., affect the quality and the condition of the skin. Formulating with ingredients that enable milder products with simplicity, pleasant aesthetics and sensory, while maintaining the performance expected by consumers, has become a challenge. A new generation of multifunctional acrylate-based polymeric emulsifier contributes to overcome the limitation of existing technologies. Mildness of this generation of polymeric emulsifier has been compared to well-known skin irritant substances by surface tension measurement. Formulators are nowadays offered with a robust and highly efficient solution for emulsion stability and mildness without compromise on the pleasant sensory and the variety of galenics in the skin and sun care markets.

Nevertheless, because of environmental and legislative pressures, there is an increasing demand for high quality Direct-To-Metal products able to substitute solvent-borne technologies such as alkyds.
This paper introduces a new cost-effective concept : an innovative binder, designed for DTM enamels, with the following key advantages : Excellent adhesion on ferrous & non ferrous metals, high initial gloss and gloss retention, outstanding water resistance and salt spray resistance without anticorrosive pigment.Note de contenu : - POLYMER DESIGN CONSIDERATIONS : Adhesion - Water resistance - Permeability - Latex particle morphology

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

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Architectural exterior coatings are subject to the harsh elements of the environment. Careful consideration must be paid to these harsh conditions to overcome deleterious effects of these elements. The novel polymer developed using innovative polymer engineering has outstanding performance for paint and primer in one exterior coatings application. This polymer can be used to formulate <25 g/l VOC coatings. A benchmark study involving market leading competitive binders shows that the novel polymer outperforms in DPUR, leaching resistance, tannin blocking, efflorescence resistance, scrub resistance, corrosion resistance, gloss retention, and tint strength. Natural weathering shows excellent results at 36 months of testing.
