Main features

  • Low-Shrinkage Glass Assembly
  • Fast Dissimilar-Material Bonding
  • Heat- and Moisture-Resistant Bonds

Product Description

Dymax 431-T Glass, Plastic and Metal Bonding Adhesive delivers UV- and visible-light cure for bonding glass, plastics, metals, and ceramics. The low-shrinkage formulation is intended for assemblies that need a dimensionally controlled bondline across dissimilar materials. Product characteristics include high-temperature and moisture resistance for bonded components exposed to demanding environments. Fast light cure on accessible bond regions supports efficient assembly without a prolonged thermal cycle. Applications include glass assembly, mixed-material decorative or technical components, and joining the listed substrates where low shrinkage and environmental resistance are important selection factors.

Key features

  • Low-shrinkage bond formation: The formulation limits cure shrinkage for dimensionally sensitive assemblies.
  • Broad dissimilar-material bonding: Bonds glass, plastics, metals, and ceramics within the supported substrate range.
  • Heat and moisture resistance: Cured bonds are positioned for elevated-temperature and moisture exposure.

Applications / Suitable for

  • Glass assembly
  • Dissimilar-material component bonding
  • Plastic, metal, and ceramic joining

Refractive index
The refractive index determines how much the path of light is bent, or refracted, when entering a material. It is calculated by taking into account the velocity of light in vacuum compared to the velocity of light in the material. The refractive index calculation can be affected by the wavelength of light and the temperature of the material. Even though it is usually reported on standard wavelengths it is advised to check the TDS for the precise test parameters.

Thermal Properties
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
