Kedu ihe bụ mkpuchi ntụ ntụ acrylic
acrylic ntụ ntụ mkpuchi ntụ ntụ nwere ihe ịchọ mma mara mma, nguzogide ihu igwe, na nguzogide mmetọ, ma nwee isi ike dị elu. Ezi mgbanwe. Ma ọnụahịa dị elu na nguzogide corrosion adịghị mma. Ya mere, mba Europe generaljiri ntụ ntụ polyester dị ọcha (resin nwere carbonyl, ejiri TGIC gwọọ ya); (hydroxyl nwere polyester resin na-agwọ ya na isocyanate) dị ka mkpuchi ntụ ntụ na-eguzogide ihu igwe.
