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.

The usage instructions are recommendations based on the tests we have conducted and are based 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. Insofar as 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. We guarantee consistent quality of our products. We reserve the right to make technical changes and further develop products.

Safety data sheet

Application area

Butyl primer is always required to ensure optimum adhesion on porous and absorbent surfaces. To improve adhesive strength on oxidising metals such as iron, lead etc., these surfaces too must always be treated with pre-primer. For other surface materials, the adhesive strength can be increased by using the primer.



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


  • Butyl tape/butyl round cord

  • Butyl tape with aluminium and fleece lamination

  • Bitumen tape with aluminium, unpainted copper or aluminium terracotta lamination

  • Indoor sealing fleece

  • Indoor sealing tape/outdoor sealing tape


Butyl primer must be used on:


Concrete, aerated concrete, bitumen, lead, iron, fibre cement, natural stone/artificial stone.



Adhesive strength can be optimised with butyl primer:


Acrylic glass, acrylic paint, alkyd resin lacquer, bare aluminium, anodised aluminium, chlorine rubber varnish, chrome, DD varnish, dispersion window varnish, dispersion façade paint, stainless steel (V2A) (V4A), enamel, epoxy enamel, glazed and unglazed tiles, glass, copper, scumbling coat, marble, melamine resin (Resopol), brass, polycarbonate, polyester (GFRP), hard PVC, untreated and galvanised steel, polystyrene, zinc plating, zinc dust paint.

Instructions

The surface to be primed must be dry, load-bearing and free from dust and release agents. Apply the primer evenly (apply a thicker coat to porous surface materials).

Packaging unit

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.

Structure of our article number

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
