Vernis bi-composantIndex. décimale : 667.9 Revêtements et enduits Résumé : A 100% active diol modifying resin designed to enhance the performance of 2-component polyurethane coatings has been developed.
Polyurethane floor coatings require good abrasion resistance, hardness, chemical resistance and stain resistance. They also require good mechanical properties like tensile strength, hardness, ftexibility and tear resistance. A challenge for polyurethane coating formulators is to develop systems that meet these requirements with resin systems that have low viscosities without the use of volatile solvents.
A unique 100% active diol modifying resin designed to enhance the performance of 2-component (2K) polyurethane coatings has been developed. Four 100% non-volatile floor coating studies will be reviewed demonstrating the effect of modifying aromatic and aliphatic polyurethane systems. This diol modifying resin helps to produce films with higher tensile strength, elastic modulus, better abrasion resistance, higher hardness and improved chemical resistance versus the control formulations.Note de contenu : - PRIMARY HYDROXYL GROUPS AND REACTIVITY WITH POLYISOCYANATES

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Flooring systems must meet an ever-increasing range of demands on their performance and efficiency. To meet these requirements, there have been significant technology advancements of epoxy curing hardeners in recent years. This article presents epoxy curing agents that enable floor coating formulators to comply with low emission and sustainability targets while fulfilling high expectations on processing speed and aesthetics.

Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : Authors explain why waterborne two component polyurethane systems are finally good enough to use in trafficable coatings.
Waterborne two-component (2K) polyurethane (PUR) coatings have long proven suitable for a wide variety of applications, such as the coating of plastics and wood. However, waterborne 2K polyurethane systems have not yet been able to establish themselves in the formulation of trafficable floor coatings (e.g. automobile showrooms, garages, etc.) due to the special requirements of such applications.
In recent years the development of new waterborne binders has improved the performance of coating materials formulated with these binders to such and extent that we can now present cosolvent-free, manually mixable systems with above-average mechanical and chemical properties, which even satisfy the requirements of trafficable floor coatings.Note de contenu : - Identical crosslinking behaviour of waterborne and conventional polyurethanes
- Film quality is virtually independent of the climate- No winter/summer quality

- Waterborne 2K polyurethane systems take over yet another field of applicationPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27619
