Lloyds Approved

Altek® H520 Series

General Purpose Orthophthalic Laminating Resin Altek® H520 is a prepromoted, thixotropic, general purpose low reactive orthophthalic polyester resin.

  • Low Exotherm
    The low exotherm of Altek H520 allows for the application of thick laminate sections that can cure at one time without the generation of excessive heat.

  • Good Secondary Bonding
    Altek H520 provides good chemical bonding between laminate application if proper application procedures are followed.

  • Superior Mechanical Properties
    When used with the proper glass reinforcement content, BUFA Composites Altek H520 produces a composite with superior mechanical properties that can assist in the reduction of cracking.

  • Catalyst Indicator Dye
    Resin colour changes from blue to neutral after addition of peroxide. This colour change provides a visual assurance to the fabricator that the peroxide has been mixed with the resin.

Vinyl Ester

H034 ADX

Hydropel Modified Vinyl Ester Resin

  • Maximum resistance to osmotic blistering when used for the skin coat of the complete composite.

  • Excellent strength and toughness of the finished composite part.

  • Provides improved resistance to cracking caused by the flexural failure of the laminate even when used only for the skin coat.

  • Good surface profile, with reduced post cure on finished parts.

  • Provides the toughness and resistance to heat needed to make durable tooling that will require minimal maintenance.
