Product Description

Poly(n-butyl methacrylate) (PnBMA) is a hydrophobic, soft acrylic polymer with excellent flexibility and impact resistance. It exhibits lower glass transition temperature (Tg ~20-30°C) compared to PMMA, offering improved elasticity while maintaining optical clarity and UV resistance.

[η] = 0.50 Applications: Flexible Coatings: Enhances weatherability and mechanical strength in automotive and industrial coatings. Adhesives & Sealants: Provides tackiness and adhesion in pressure-sensitive applications. Polymer Blends: Modifies impact resistance in thermoplastics and composites.
