Gripping primer for PROTECTAKOTE 0.60 Kg

In many situations, single-component polyurethane resins, due to their chemical cross-linking (compared to the physical characteristics of water-based products), do not have exceptional adhesion to substrates. The main cause of the difficult adhesion is the very high cohesion of the polymers inside the paint which have very high molecular weights with the total lack of absorption and penetration on some materials.

Indications for use:

PU PRIMER allows the waterproofing membranes to adhere to different materials and to obtain adhesion “connections” between the layers.
It does not form a film and has no mechanical properties, but it provides extreme adhesion for one component polyurethane products.
NOTE: It is not recommended to apply polyurethanes to substrates that are damp, wet, oil-stained, greasy or dirty.

APPLICATION:

• Apply the product evenly and generously on the clean and dry substrate.
• The recommended quantity is around 200 g / m2.
• This product can be applied with the roller by brush or spray.
• It is not advisable to wait more than 4 hours between applying PU PRIMER and the next layer.
