Improved adhesion on rough, porous and absorbent surfaces. Also suitable for bitumen tapes

Improves adhesive strength


  • Excellent adhesion to a wide range of surfaces

  • Rough and porous surfaces are strengthened


Simple use


Apply butyl primer to the surface being treated with a brush and let the surface flash off until the primer stiffens and exhibits a strong surface adhesiveness.

Notice

Thin thickened primer with light petrol to apply it again.

The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. If our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately.

Application area

Butyl primer is always required for optimal adhesion on porous and absorbent surfaces such as concrete, aerated concrete, plaster, cement stone, gypsum, wood, fibreboard, chipboard or gypsum board, masonry, sand-lime brick, etc. To improve adhesive strength on oxidised metals such as iron, lead, etc., these surfaces must also always be treated with a primer.


Can also be used for pre-treatment of adhesive surfaces in roof and concrete construction and for sealing of construction joints with butyl tapes.


Butyl primer is required for all self-adhesive Würth butyl and bitumen tapes.

Instructions

The surface to be primed must be dry, load-bearing and free from dust and release agents.


Apply the primer evenly and undiluted once with a brush (apply more thickly to porous substrate materials).


On surfaces that may be slightly damp and very absorbent, longer drying times must be allowed for until the adhesive film becomes surface dry. Surface contamination of the exposed adhesive film must be avoided. Apply the butyl primer only as wide as matches the required adhesive width of the butyl tape being applied. The flash-off time (physical drying) of the applied adhesive layer depends on the thickness of the layer and the ambient temperature and is approx. 10 minutes at 20°C. Only then should the respective butyl tape be attached. When used indoors, adequate ventilation must be ensured.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076
Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).

Important information:

The information given is based on experience and laboratory conditions and is designed as a guide. However, the actual suitability of a glove depends on the individual conditions of its use and must be confirmed by an appropriate test under operational conditions. Given the variety of materials and chemicals used, the possibility of incompatibility or usage problems for the wearer cannot be excluded in individual cases. We would be happy to advise you about optimum solutions.
