Brief description：FTIR is the go-to technique for identifying the chemical structure of polymer materials. It can quickly recognize resin types, fillers, and additives through characteristic absorption peaks. Dehui represents Thermo Fisher and Agilent FTIR systems, equipped with diamond ATR accessories, and can complete the qualitative analysis of adhesive layers in 30 seconds. It's an efficient tool for adhesive R&D and IQC raw material acceptance.
Industry Applications：Quick identification of the resin type in pressure-sensitive tape adhesive layers (acrylic/rubber/silicone/polyurethane); infrared fingerprint recognition of adhesive raw materials upon arrival; semi-quantitative assessment of the ratio of soft to hard monomers in acrylic copolymers; monitoring the adhesive curing process (tracking the conversion rate of epoxy/polyurethane functional groups); infrared micro-area analysis and database matching identification of unknown adhesive layers/contaminants, etc.
Detailed
Fourier Transform Infrared Spectroscopy (FTIR) is the go-to technique for identifying the chemical structure of polymer materials. It quickly identifies the type of resin in adhesives (like acrylates, polyurethane, silicone, epoxy, etc.), as well as the kinds of fillers and additives through characteristic absorption peaks. Thermo Fisher and Agilent FTIR systems, distributed by Dehui, come with diamond ATR attachments for non-destructive, direct detection of solids, liquids, and film samples—no complicated prep needed. For pressure-sensitive tapes, FTIR can qualitatively identify the adhesive layer composition in just 30 seconds, figuring out whether it’s acrylate, rubber, or silicone-based. Combined with spectral library searches and quantitative methods, it can even give a semi-quantitative evaluation of copolymer composition—making it a super handy tool for adhesive R&D and raw material IQC checks.
Industry applications:
- Quickly identifying resin types in pressure-sensitive tape adhesive layers (acrylate/rubber/silicone/polyurethane)
- Infrared fingerprint checks for incoming adhesive raw materials (resins, tackifiers, fillers)
- Semi-quantitative evaluation of soft and hard monomer ratios in acrylate copolymers
- Monitoring adhesive curing processes (tracking functional group conversion in epoxy/polyurethane systems)
- IR micro-area analysis and database matching of unknown adhesive layers or contaminants
