Hydrolyzable UV Adhesive Warm Water Washable Easy Peel for Glass Wafer Temporary Fixing Protection

Hydrolyzable UV Adhesive Warm Water Washable Easy Peel for Glass Wafer Temporary Fixing Protection

Hydrolyzable UV Adhesive is a clear, amber transparent UV-curable adhesive for the temporary fixing and protection of glass wafers. It has strong flow for easy coating and, once UV cured, holds the wafer firmly during grinding, thinning and processing. After processing, it can be hydrolyzed and washed away in warm water, so it peels off easily with no residue and no secondary contamination.

Operation Guide

1. Surface preparation: clean the wafer to remove oil, dust and contaminants.
2. Application: apply the adhesive by flow coating for even coverage.
3. UV curing: expose to UV light at 400 mJ/cm² until fully cured.
4. Processing: proceed with grinding, thinning, polishing or dicing.
5. Debonding: hydrolyze and wash off the cured adhesive in warm water.
6. Inspection: verify no residue remains on the wafer surface.
