Arboflex 500 is a high grade, butyl rubber based non setting compound intended for glazing beaded frames.

Recommended for glazing single glass into painted steel or paint finished timber frames, for glazing double glazed units into painted steel or painted/ stained timber frames as part of the MVP glazing system in conjunction with appropriate Adshead Ratcliffe sealants (contact Adshead Ratcliffe Technical Service Department for further information). Compatibility of Arboflex 500 with any particular edge sealant should be checked with the manufacturer of the IG unit or the glass supplier.

Recommended accessories:

  • Arbo Cleaner No. 17 (Xylene based – not suitable for use with plastics or delicate finishes).
  • Arbo Cleaner No. 16 (Alcohol based).


Technical data:

  • Application temperature: 5–30ºC.
  • Cure rate at 20ºC/ 65% RH: Arboflex 500 forms a protective skin within three days (remainder of the material underneath remains uncured).
  • Painting: Not usually necessary as bedding lines left exposed after glazing has taken place will perform satisfactorily for many years without painting. However, Arboflex 500 can be painted with most common paint finishes if required.
