CORROCOAT
Corrocoat Vinyl Ester Polymer Concrete
Product reference: 3/23
Product title: Corrocoat Vinyl Ester Polymer Concrete
Valid from: 7th April 2016
Last reviewed: May 2019
Type
A low shrink, vinyl ester polymer concrete, supplied as 3 components for mixing on site.
Suggested use
Corrocoat Vinyl Ester Polymer concrete may be used to lay screeds, cast slabs of up to 100mm thickness, or manufacture many items normally manufactured fromstandard concrete. It has advantages over standard concrete in that it is chemically resistant and has higher mechanical strengths. Unlike standard concrete, Vinyl Ester Polymer Concrete will bond to correctly prepared concrete or steel surfaces and may be used to repair existing concrete structures.
Limitations
Should not be used at temperatures higher than 212°F (100°C). Normally overcoated where chemical service is arduous.
Health & safety
Before commencing work, read the product Health & Safety data sheet. Only to be used by adequately trained personnel
Surface preparation
Concrete: Grit Blast to remove surface laitance. For best results prepare surface as per Corrocoat Surface Preparation SP5 and prime accordingly.Metals: Grit blast to SSPC-SP10 (ISO 8501-1 SA 2½) or equivalent and prime accordingly.Corrocoat Vinyl Ester Polymer Concrete can be applied directly onto the substrate although the adhesion will be significantly reduced. Priming where possible is advisable.
Packaging
1 Gallon and 5 Gallon Kits.
Storage life
6 Months if stored at temperatures below 68°F (20°C) and away from direct heat and sunlight.
Mixing ratio
15% Base: 85% Aggregate by weight(Base Equals 98% Resin and 2% Organic Peroxide)
Mixing procedure
Thoroughly mix the catalyst with the resin, then add the aggregate ensuring that the product is thoroughly wetted and mixed throughout. A heavy-duty paddle may be used to mix the product or alternatively the product may be mixed in certain types of mixing machine provided that the unit is thoroughly cleaned after each mix.
Application
It is recommended that Corrocoat Vinyl Ester Polymer Concrete is not applied to unprepared surfaces, see surface preparation above. The concrete may be poured or trowelled in the normal manner up to 20mm thickness where shrinkage. Air bubbles can be removed as with conventional concrete by vibrating and the surface can be floated using a styrene wetted trowel.The Corrocoat Vinyl Ester Polymer Concrete has high slump and hold up on vertical surfaces will be very limited. It is therefore necessary in most instances to shutter vertical surfaces.Reinforcing bars and mesh may be used to increase mechanical strength and crack resistance. Where these materials are used, they should be grit blasted first to remove any oxide films and ensure good adhesion.
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).
Catalyst type
P2.
Cure time
At 68°F (20°C) tack free in 4 hours.
Cleaning solvent
Prior to gelation – Acetone or Methyl Ethyl Ketone.
