Corunex PU Mastik

• It is a ready-to-use, single component sealant and filling material.
• Cures without bubbles
• It maintains its elasticity for many years without losing volume.
• It does not sag and is resistant to aging and abrasion.
• It is not affected by temperature changes (-40°C to +80°C) and many chemicals (diluted).

The surfaces to be applied must be solid, clean, dry, and free from oil and dust. - Tape can be applied to both edges to ensure the filling is smooth.

If necessary, the closed cartridges can be heated in a water container to +10°C to +20°C.

For coated surface applications (e.g. hydrophobic facades) a preliminary check of suitability is necessary.

Especially in acrylic coating materials, a loss of adhesion may be possible due to the softening agent.

During application, care should be taken to ensure that the width / depth ratio is 2 / 1.

Backer rod should be used in joints to provide the desired depth when necessary.

If the mastic sticks to three surfaces during application, there is a risk of adhesion failure in the joint material. It should only stick to two opposite surfaces. In such cases, the joint sealant should be cleaned with adhesion preventive gasoline or alcohol between the surface or backing rod.

After curing is complete, it is only cleaned mechanically.

• Before using the cartridge, its mouth is cut and a plastic tip is attached.
• The tip of the tip is cut according to the width of the application surface and the cartridge is inserted into the gun.
• The metal cap at the bottom of the gun is removed and the cartridge is placed into the gun.
• During application, joints must be filled at once and without leaving any gaps.
• The sausage wrapper is cut from one end and placed in the appropriate gun.
