Polyurethane Based, Waterproofing Material for Potable Water Tanks - POLIXA 2

Description

Two component, polyurethane-based, solvent-free liquid waterproofing material for especially potable water tanks.

Fields of Application

Especially developed for waterproofing metal or concrete water tank insulation.
On concrete, marble, plaster, stone, wood and metal surfaces for waterproofing and coating.
On concrete or ceramic coated terrace for waterproofing or floor coating, if UV resistant coating is applied on the top.
Used for providing a waterproof coating resistant to light car and pedestrian traffic.

Features and Benefits

Solvent-free. Safely used in interior areas.
Suitable for potable water tanks.
Excellent adhesion performance.
High abrasion and impact resistance.
Resistant to corrosion.
No harmful effect to health.

Application Procedure

Preparation of Substrate

The application surface must be durable, dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. POLIXA 2 results foaming when applied to wet surfaces. For this reason, EPOX PR 300 should be used on concrete surfaces as a primer.

Application Method

Application temperature should be between+ 5°C to + 30°C. Component B, hardener, is slowly poured into Component A, main component, under the low speed drill and continue mixing until obtaining a homogenous mixture without any agglomerate (approximately 3-4 minutes). The mixture must be consumed within 30 - 45 minutes; later it cannot be applied due to jelling. Mixture should be applied with a brush or roller as 2 or 3 layers. Brush application direction in each layer must be perpendicular to each other. Each coat must be applied 6 hours later than the preceding coat. If this interval exceeds 24 hours, the first coat must be sandpapered prior to the application of the second coat. After the application the surface must be protected from water, rain for at least 6 - 8 hours. Dry sand should be added on POLIXA 2 while floor coating.
