Fosroc Polyurea WH 200

Description
Fosroc Polyurea WH 200 is a spray-applied, 100% solids, flexible, two-component, rapid curing hybrid polyurea/ polyurethane system, designed as a waterproofing and protective coating.It combines the advantages of seamless coating with long life cycles and high durability. Fosroc Polyurea WH 200 consists of two main components. Fosroc Polyurea WH 200 Part A ISO; Fosroc Polyurea WH 200 Part B AMINE. The system off ers excellent surface properties and overall physical properties. See Fosroc Polyurea WH 200 Method Statement for application protocol and further detailsUses
Waterproof and protective coating for concrete and steel in a wide range of environmental conditions.

Typical Applications Include:

• Podium decks
• Roof gardens
• Green roofs
• Stadium stands
• Service roofs
• Cut and cover tunnels

Advantages

• UV stable
• Environment friendly – zero VOC
• Fast turn-around time.
• Excellent impact, abrasion and puncture resistance
• Seamless and monolithic, including fi eld joints
• Enhances the durability of reinforced concrete
• Low permeability values
• Colour stable when coated with Nitoproof UVR Topcoat
• Fire rated when coated with Nitoproof UVR Topcoat
• Designed for service temperatures from -20OC to +80OC
• Under prolonged UV exposure only colour may fade but no eff ect on the performance parameter of the product.

Specification:-
Where mentioned in the contract drawings, the protective and waterproofi ng coating shall be Fosroc Polyurea WH 200, 100% solids, flexible, two-component, rapid curing hybrid polyurea/polyurethane coating system providing high corrosion resistance, abrasion and waterproofi ng resistance

Clarification of property values:-
The typical physical properties given above are derived from independent verified testing of Fosroc Polyurea WH 200 spray-applied in accordance with the Fosroc Polyurea WH 200 Method Statement with Probler P2 gun in controlled laboratory environment and tested after a minimum of 14 days cure. Results derived from testing fi eld-applied samples may vary dependent on circumstances beyond our control such as the type and condition of equipment utilised, static and dynamic working pressures, application temperatures and weather conditions, fi lm thickness, test and curing conditions and age of samples tested. A water sinking test must be carried out and a “pass” achieved (sample sinks in water) prior to spraying.

Project Log
A Project Log should be maintained for each Polyurea WH 200 site application. For details of Project Log requirements refer to the Fosroc Polyurea WH 200 Method Statement.

Instructions for use
Surface Preparation
All surfaces must be clean, dry and free from contamination. The surface must be assessed and treated in accordance with ISO 8504.

Concrete
Dry abrasive blasting, wet abrasive blasting, vacuum-assisted abrasive blasting, and centrifugal shot blasting, as described in ASTM D4259, may be used to remove contaminants, laitance, and weak concrete, to expose blow holes, and to produce a sound concrete surface with adequate profi le and surface porosity. All blow holes and minor surface imperfections shall be fi lled with recommended fi ller prior to application of Primer.
