These products offer two distinct curing advantages. The adhesive can be cured first which then allows for assembly of the parts at some future point. This provides the ability to bond any substrate; clear, translucent or opaque. This material can also be cured through previously assembled clear or translucent substrates in the traditional UV curing mode. This adhesive can bond a wide range of substrates including PE, PP, Delrin and most plastics, metals, glass or ceramics. It can be sprayed, roll coated, screen or stencil printed, valve dispense or brush applied.
CTECH™ UV PSA 19-177-5A is distinguished from any other light curable PSA by the broad process latitude for curing dose, film thickness and age. The product line is available in a range of viscosity that can be applied at room temperature and can be tailored for tack, peel and creep performance.
CTECH™ UV PSA 19-177-5A cures rapidly to a high tack, crystal clear PSA with low residual odor and stable properties when stored under release liners.
- Features and Benefits
- Solvent-free, 100% solids formulation for low environmental impact
- Reusable for low waste
- Long shelf life un-cured to optimize inventory
- Long shelf life of cured films to optimize finished goods
- UV curable for instant processing and shipping of products
- Any application method can be used so that the benefits of a PSA can be realized for any shape, configuration and substrate
- Films/beads from 0.1 – 20 mils for many different uses in addition to PSA films
- Superb manufacturing latitude creates a high quality process
- Unsurpassed combination of peel and creep resistance maximizes the uses of Tru Bond PSA
- Sensitive to visible wavelengths for curing through UV blocked / translucent substrates
- Cures to crystal clear, optically transparent PSA that maintains clarity for years
Applications & Uses

- Uses and Applications
- Sign making and other graphic assembly
- Touch pad, membrane pad and other keypads
- Automotive interiors – trim, graphics, light panels
- Lamination of foam, foils, any plastic film, felt, mesh etc
- Form-in-place gaskets and O-rings
Replace die cut forms
Replace press-fit, snap-fit tabs on parts for lower cost molded parts
- Traditional tapes and films replacing solvent and water carried PSAs
- Processing
ITW Devcon products are easily applied by syringe dispense or specialty valve spray units. The materials cure extremely fast in bondlines, e.g. where the surfaces are not exposed to air, with UV or Visible radiation. Exposure doses range from 0.25 - 2 J/cm2 depending on the intensity of the lamps and configuration of the assembly.
