Iso Butyl Methacrylate (IBMA)

CAS#: 97-86-9
Synonyms: Isobutyl 2-methylpropenoate

Iso Butyl Methacrylate (IBMA) is a versatile methacrylate monomer valued for its ability to improve flexibility, impact resistance, and long-term weatherability in polymer systems. Its branched isobutyl structure contributes to enhanced toughness and outdoor durability, making it a common choice for high-performance coatings and specialty acrylic resins. IBMA also helps reduce brittleness while maintaining excellent clarity and UV resistance.

Key Features:

• Improves impact resistance and flexibility in acrylic systems

• Enhances weatherability, UV stability, and outdoor durability

• Offers reduced brittleness while maintaining clarity

• Provides good compatibility with other methacrylate monomers

Applications:

• Exterior and industrial coatings requiring enhanced weather resistance

• Adhesives with improved toughness and flexibility

• Acrylic resins and copolymers for impact-modified or durable formulations

• Sealants and plastics where outdoor stability is essential
