RAPID COMMUNICATION: New generation of cationically UV-cured epoxy
adhesives containing dyes (in English)
Polimery 2004, No 7-8, 561
A new class of cationically UV-cured epoxy resin base adhesives containing dyes and allyl or 1-propenyl ether modifiers has been elaborated. The dyes (commercial product of Ciba) were directly applied into the systems and showed very good solubility in compositions studied. Model ethers containing OH groups, i.e. monoallyl or mono-1-propenyl ether of butane-1,4-diol (MoAlE and MoPnE, respectively) have been chosen as modifiers. The effects of the type of dye on UV-reflection, adhesion to glass and the shear strength have been determined. The obtained adhesives were intensively colored, transparent, and characterized by very good adhesion to glass and high cohesion at room temperature.
