Q1: What is the primary function of TIRES 213 in coating formulations?
A: TIRES 213 serves as a hydroxyl-functional acrylic resin designed to act as a reactive binder in two-component polyurethane and polyester-based coating systems, contributing to crosslink density, film hardness, and chemical resistance.
Q2: Is TIRES 213 compatible with common isocyanate crosslinkers used in industrial coatings?
A: Yes, TIRES 213 is formulated for compatibility with aliphatic and aromatic polyisocyanates, including HDI-based and IPDI-based hardeners, enabling robust curing under ambient or elevated temperature conditions.
Q3: How does TIRES 213 support performance in tire-related applications?
A: As part of Allnex’s TIRES product family, TIRES 213 is engineered to deliver balanced flexibility, adhesion to rubber substrates, and resistance to flex cracking—key requirements for coatings on tire components such as sidewalls or decorative trim.
Q4: What solvent systems is TIRES 213 typically supplied in, and are adjustments needed for VOC-compliant formulations?
A: TIRES 213 is commonly supplied in aromatic or ketone-based solvent blends; it can be adapted to low-VOC or solvent-reduced systems through careful solvent exchange or integration with high-solids acrylic resins, depending on regulatory and application requirements.
