Adhesives get a grip on PCB substrates

Dymax Ultra Light-Weld 3094 Series UV/visible light curing adhesives from Intertronics form strong, durable bonds to most plastics in seconds.

Dymax Ultra Light-Weld 3094 Series UV/visible light curing adhesives from Intertronics form strong, durable bonds to most plastics in seconds.

Bonds are clear, cause no crazing or blooming on plastics, have excellent gap filling capability and maintain strength through thermal cycling, shock, vibration and impact.

The adhesives form strong bonds on an expanded range of plastics and other substrates including UV absorbing clear or tinted plastics, as well as other semi-transparent materials such as FR-4 circuit boards and white ceramics.

Recommended plastics include polystyrene, polycarbonate, acrylic (PMMA), PET and PVC.

Typical applications include laminating and packaging, polycarbonate housings, metal to plastic constructions, acrylic shelving and racks and polystyrene novelty items.

3094 adhesives are available in viscosities of 1000, 8000, and 25,000 cP non-flowing gel, to meet most dispensing and application requirements.

They also serve as excellent gap fillers between imperfectly fitting plastic parts.

The adhesives cure on exposure to wavelengths ranging from 300-500nm, producing fast and deep cures.

3094 is sensitive to the spectral output of both visible and UV curing wavelengths, so it cures faster and deeper with lower intensity and less expensive lamps, compared with adhesives that respond only to UV light.

Ultra Light-Weld products provide the performance advantages of "bond on demand" assembly - with curing not commencing until exposure to light - allowing precise alignment of parts and generous adjustment time prior to instant light-driven cure.

Ultra Light-Weld adhesives are 100% solvent and ODC free.

Along with their excellent depth and speed of cure, they are an ideal replacement for products containing ozone-depleting chemicals.
