Adhesion on ETFE Film
Sep, 2020
Improvement of ETFE adhesive properties for lamination and inclusion in composite structures
Customer challenge
Inadequate adhesion produced by current surface preparation technologies e.g. wet-chemical primers and corona plasma
Solution
Grafting of a silane nanolayer onto the ETFE film surface using Molecular Grip technology
Current capacity -> roll-to-roll up to 1.6m width
Results
- Exceeded target peel value by >15%
- Unaltered peel strength after accelerated ageing tests
- Open-time = minimum 1 year optimize supply chain and cost savings
