Trixene® Aqua BI From LANXESS - Water-Dispersible Blocked Polyisocyanates for Coatings and Adhesives
Trixene® Aqua series used as crosslinker and adhesion enhancer for industrial coatings and lacquers.
Trixene® Aqua grades offer a wide pH latitude including anionic, nonionic and cationic species with good formulation compatibility. Used in coatings and topcoats for flexible and rigid surfaces.
Improved Coating Performance and Protection
• Increases surface and interlayer adhesion performance.
• Improves chemical, impact and abrasion resistance.
• Provides durability according to weather conditions.
Formulation Benefits
• Applicable eg. spraying, dipping, roller/blade/curtain coating, brushing,
• Heat curing for controlled reactivity (no free isocyanate groups).
Trixene® Aqua acts as a crosslinking and bonding agent for a variety of flexible and rigid substrates.
Fiber Sizing
With Trixene® Aqua Crosslinkers used in glass fiber sizing,
• Improve integrity and reduce fluff formation.
• Improves compatibility with a resin matrix (eg resins such as PA, PES, Epoxy).
• Provides maximum efficiency with Lanxess’s Witcobond® Pud products.
• Increases higher glass/polymer matrix interaction and strength.
• Provides improved bond strength between reinforcement and polymer.
• It reduces the formation of solid residues in the process.
• Provides higher elasticity, impact and tensile strength.
Textile & Fabric
• Trixene® Aqua offers highly flexible coatings. Offers a variety of unblocking temperatures for textile and fabric coatings.
• It increases the tensile strength under severe conditions, in fiber impregnation oven coatings, to increase adhesion. It provides washing resistance.
• Trixene® Aqua blocked crosslinkers improve adhesion of fluorochemical and other aqueous finishes to natural and synthetic fabrics.
Adhesion enhancer for aqueous, fluorocarbon-based water repellents.
• 2K based on C8 (PFOA & PFOS) eliminates solvent applied finishes.
• Allows the transition to aqueous fluorochemicals based on “safer” C6 and C4 chemistry.
• Allows formulating 1K, covert cure C6/C4 systems with low or no VOC content.
• Non-ionic grades, eg. Trixene Aqua BI 220 provides a wide pH/formulation range.
• Apply to substrate (eg woven polyamide, polyester) by padding or roller.
• Dry at high temperatures (~150 °C, 3-5 minutes).
• Provides superior water, oil repellency, improved durability, dry cleaning resistance.
Coatings
• Improves adhesion to substrate and successive layers.
• Increases impact, scratch and chemical resistance on the coating surface.
• Provides excellent color retention.
