Product reference: 1/17

Product title: Corroglass AR Veilcoat

Valid from: 27th November 1997

Last reviewed: 31 May 2019

Type: A two-pack cold cured modified Vinyl Ester/Acrylic Co-Polymer Veilcoat.

Suggested use

Corroglass AR Veilcoat has been specially formulated to offer the best resistance to base environments, e.g.Sodium Hydroxide and Sodium Hypochlorite, the resin and cure system having been modified to impart the optimum resistance to these environments. Corroglass AR Veilcoat is to be used as a surface veil in certain applications where the glass present in the AR4 may be attacked by the environment.

Health & safety

Before commencing work, read the product Health & Safety data sheet. Corroglass AR Veilcoat should only be used by adequately trained personnel.
