Curamento de tinta UV por LED UV é um processo em que a luz ultravioleta emitida por diodos emissores de luz (LEDs UV) é usada para endurecer ou secar tintas UV. A luz UV inicia uma reação química na tinta, fazendo com que ela solidifique e adera ao substrato.
As aplicações de curagem de tinta UV por LED UV incluem:
Impressão digital: em grande formato para banners, cartazes e envolturas de veículos.
Impressão de rótulos: Para rótulos de produtos e embalagens.
Impressão 3D: Para solidificar tintas UV usadas em objetos impressos em 3D.
Impressão offset: Melhoria do processo de secagem na impressão offset.
Impressão têxtil: Aplicado na impressão em tecidos e vestuário.
Impressão de cartões: tais como cartões de crédito e cartões de identificação.
Impressão de embalagem: Para caixas e recipientes.
Impressão cerâmica: Sobre superfícies cerâmicas.
O processo de cura com diferentes tipos de tintas UV funciona através de um mecanismo semelhante, mas pode ter variações com base na composição da tinta e requisitos específicos.
A maioria das tintas UV contém fotoiniciadores que absorvem a luz ultravioleta emitida pelos LEDs UV. Quando expostos à luz UV, os fotoiniciadores geram radicais livres ou cátions, que desencadeiam uma reação em cadeia. Esta reação leva à reticulação e polimerização dos componentes da tinta, transformando a tinta líquida em um filme sólido e durável.
No entanto, diferentes tipos de tintas UV podem ter diferentes características de cura. Algumas tintas podem exigir intensidades mais altas de luz UV para curar adequadamente, enquanto outras podem ser mais sensíveis e curar a intensidades mais baixas. O comprimento de onda da luz UV também pode afetar o processo de cura. Diferentes tintas podem responder de forma óptima a comprimentos de onda específicos dentro do espectro UV.
Por exemplo, algumas tintas UV formuladas para substratos flexíveis como plásticos podem ter aditivos para aumentar a flexibilidade após a cura. Estas tintas podem curar a uma taxa ligeiramente diferente e com propriedades finais diferentes em comparação com tintas projetadas para materiais rígidos como vidro ou metal.
Tintas usadas na impressão 3D podem ter um processo de cura que é estreitamente coordenado com a deposição camada por camada do material para garantir uma ligação precisa e forte entre cada camada.
No geral, o processo de cura para diferentes tipos de tintas UV é adaptado para alcançar as propriedades desejadas, tais como adesão, dureza, flexibilidade e resistência à cor com base na aplicação final e no substrato.
