01 / THE PEOPLE BEHIND THE BOND

Experience in chemistry.
Understanding of industry.

The adhesive is one part of your product. We take time to understand the whole process.

Adhesive pioneers.
By your side.

Founded in Türkiye in 2018, OYTI brings together chemists and engineers with experience across European adhesive markets. From our production base in Yalova, we develop bonding solutions for manufacturers working with foam, textiles, decorative films and other industrial materials.

Our work begins with a conversation about your materials, equipment and production goals. Development, laboratory evaluation and manufacturing then work together to turn those requirements into a practical adhesive solution.

Materials. People.
A shared understanding.

Progress starts
with a conversation.

We also value dialogue beyond the production line. Welcoming representatives from Gebze Technical University alongside Yalova University’s Technology Transfer Office offered an opportunity to exchange perspectives on research, development and university–industry collaboration.

02 / HOW WE WORK

Built around your process.
Supported beyond the start.

From the first application discussion to everyday production, we work with you to match the adhesive, the process and the support you need.

Adhesives tailored to your application

We start with your substrates, equipment and target performance. Where your process calls for a different balance of properties, we work on product adjustments and customised adhesive development around those requirements.

04 QUALITY & TRACEABILITY

Quality is
part of the process.

Quality connects the materials we receive, the way we manufacture and the products we release. Documented controls and traceability make that connection visible.

Our own software.
Traceability throughout the process.

Our internally developed software supports batch traceability, all incoming inspections and all outgoing inspections — bringing these essential quality records together within our own system.

Documented at each stageIllustrative process · no customer data
Material selection & incoming inspection01 / 04

Control starts
with what comes in.

Raw materials are selected for the intended adhesive system. Incoming inspections are documented in our internally developed software, linking the received material and its inspection record with the quality process. This provides a clear basis for reviewing materials before they enter production.
