Hybrid Polyurea - PUR 421

Description

PUR 421 is a two component hybrid polyurea coating system with very fast setting, rapid curing and flexible properties. It provides seamless and long-term durable waterproofing and floor coating. It is applied at high pressure with heated multi-component spraying equipment.

Fields of Application

• Roofs
• Terraces
• Industrial surfaces
• Roads
• Parking Lots
• Pipes
• Car bedliners
• Pools

Features and Benefits

• Fast reactivity and fast curing.
• Seamless and jointless coating.
• Application on vertical surfaces
• VOC free.
• Chemical resistance.
• Impact and abrasion resistance.
• Corrosion protection.

Application Procedure

Preparation of Substrate

All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. Weak concrete must be removed and surface

defects such as voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids

and surface leveling must be carried out using appropriate products.

Application Method

A and B component must be stirred with using a barrel mixer until getting homogenous mixture and color obtained. A and B component must be applied by using a two components high pressure and heat spray machine. The application temperature should be between 70-80^oC, and the application pressure should be between 120 and 200 bar.

Mixing ratio by weight: A Component: 220 / B Component: 200

Process temperature: A Component: 70-80°C / B Component: 70-80°C

Process pressure: 120-200 bar

Consumption

For 1 mm thickness polyurea coating 1,1-1,2 kg/m²  . Recommended film thickness is minimum 2 mm.

Package

A component: 220 kg barrel – B component: 200 kg barrel
