Product Details:
ArmGrout Inject PU4 is a solvent-free thin liquid, two- Component polyurethane resin. ArmGrout Inject PU4 is slow reacting and hardens to a non-foaming, non-rigid, pore free material which slightly foams when put into contact with water. ArmGrout Inject PU4 bonds to a dry, moist surface and offers an excellent adhesion and tears resistance. ArmGrout Inject PU4 has a low glass transition temperature and resists to winter temperatures without causing embrittlement and widening of cracks due to low temperatures without tearing.

Uses:
ArmGrout Inject PU4 is used for the close, waterproofing and elastic connection of cracks, joints and cavities in construction made of concrete, natural stone or bricks. ArmGrout Inject PU4 is suitable for the waterproofing of car parks, concrete tanks, tunnel linings, construction joints, furthermore, for the waterproofing injection using injection hoses. Due to its mix ratio of 2:1 parts by volume ArmGrout Inject PU4 is perfectly suited for the ArmGrout Inject PU4 can be injected via packers or embedded injection hoses

Features And Benefits:

• Non foaming & non rigid
• Excellent adhesion
• Bonds to even dry surface
• Permanently elastic, can absorb limited movements
• No shrinkage in subsequent dry conditions
• Due to its low viscosity it can penetrate into cracks
• >0.2 mm in width
• ArmGrout Inject PU4 is inert and chemically-resistant ??? Solvent-free
• Can be injected as a one component system

Instruction for Use:
Component A (polyol) and component B (isocyanate) are already supplied in correct mix ratio. The B-component is added to the A-component. The hardener has to be completely emptied into the A-component. The two components are mixed with a mixer at approx. 300 Rpm (for example drilling machine with mixer). It is important that the mixture is also stirred thoroughly from the walls and the bottom. It is mixed until a homogenous mass is achieved; the two components are to be mixed quickly.

Processing Tools:
Hand lever press, foot lever press, 1 component pump (Airless or piston pump) or 2-component pump (working with the 2-component pump requires the use of the metal special mixer when correct product quality is to be guaranteed) 

Cleaning of the Tools:
The tools have to be cleaned properly immediately after use. They are to be cleaned thoroughly with the cleaning agent FloArmToolClean. After work has finished or in cases of longer interruptions the injection equipment is to be cleaned. Material must not dry out in the equipment and plug up vital machine components. The cleaning resp. solvent agent has to have a flash point exceeding +21°C; we recommend the use of FloArmToolClean (see technical data sheet) 

The Procedure Is As Follows:

• Pump off the remaining injection material out of the injection unit 
• Rinse the top container with FloArmToolClean
• Clean the injection pump, the top container and the tubes for 5 to 10 minutes with FloArmToolClean in circulation.
• Afterwards pump the cleaning mixture into a container and rinse again with FloArmToolClean.
• In case of longer resting times the pump, the top container and the tubes have to be filled with the flushing oil.

Before the injection unit is used again the oil has to beremoved

Physiological Behaviour and Protective Measures:
ArmGrout Inject PU4 is physically harmless after complete hardening. The liquid component is harmful; Symbol Xn. In any case the general protective regulations of the occupational association vocational league, the leaflet M044 and the instructions on the bins are to be adhered to have to be regarded
