CORROGLASS
Corroglass AR4
Product reference:
2/36
Product title:
Corroglass AR4
Valid from:
27th November 1997
Last reviewed:
31 May 2019
Type
A two-pack cold cured brominated vinyl ester/acrylic co-polymer enhanced with flake glass.
Suggested use
Corroglass AR4 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.

Overcoating
May take place as soon as the previous coat has gelled
and while still tacky. Maximum overcoating time 72 hours
at 68°F (20°C).
Once the maximum overcoating time has been reached, the
adhesion values attained by any subsequent coat will reduce
dramatically. It is important to observe maximum overcoating
times and note these will vary with climatic conditions. Any
further application of coating at this juncture should be
treated as a repair, with the surface flashed over to provide
a physical key. Styrene cannot be used to reactivate the
surface and may in some cases impair adhesion.

Application equipment
For spray application use a Graco King 45:1, or similar,
airless pump, 10mm diameter (3/8”) nylon spray line. Large
bore mastic type gun with 30 to 60 thou reversible or titan
adjustable tip. As a guide, a typical tip size would be 31-35
thou with a 60° fan pattern. The size of tip and fan pattern will
vary dependent upon the nature of the work.
May be hand applied using a brush, roller or trowel.
