UV+湿気硬化型柔軟接着剤 フォトレック™B

UV + Moisture-Curing Flexible Adhesive Photolec™ B

A flexible adhesive that follows fine-line patterns and curved surfaces, expanding design flexibility.

An adhesive that combines UV curing with moisture curing. It provides rapid initial adhesion, eliminating the need for jigs or pressure retention and improving production efficiency. With no dripping and highly precise fine-line dispensing, it is applicable to bonding in narrow bezels and complex 3D curved surfaces. The adhesive also supports a wide range of uses, including bonding for automotive and large displays, as well as fixation of smartphones and optical components.

UV curing adhesive PhotolecB

Improved adhesion with changes in material and shape

With advanced driver assistance systems (ADAS) continuing to evolve, center information displays (CIDs) now offer entertainment in addition to conventional navigation and air conditioning functions, and feature more sophisticated designs and are becoming larger in size.
Displays are becoming narrower in border size, more complex in shape, using increasingly composite materials, and larger in size in order to satisfy their design and multi-purpose needs. In terms of attaching components, there are challenges such as narrower lines, applicability to complex shapes, bonding different materials, and improving bonding strength, and using conventional tape to attach these components is becoming insufficient to meet these needs.

材料・形状の変化に伴う接着力向上

Adhesives for fixing complex shapes and dissimilar materials

The UV (B stage) + moisture-curing adhesive Photolec B is a display edge adhesive that combines the strengths of a double-faced tape and an adhesive to provide both high-initial-bonding strength and reliability.
Its rapid activation of initial bonding strength eliminates the use of jigs and the need to maintain pressure. 
With no glue overflow and a high degree of freedom in dispensing, it is capable of narrow side dispensing of 0.5 mm or less, making it suitable for bonding at narrow borders. It can also be used for bonding complex 3D curved surfaces, increasing the design flexibility.
Its excellent bonding property for different materials allows it to be used for various types of surfaces.
Its flexibility even after curing prevents warpage of components by stress relaxation.
