Würth Varioprimer is a versatile, high-performance primer developed to improve adhesion in replacement glazing applications. Designed as a 4-in-1 solution, it functions as an adhesion agent, corrosion inhibitor, activator, and UV protection for adhesives, making it suitable for a wide range of automotive and body repair applications.
Adhesion Promotion and Protection
The primer is black and moisture-hardening, providing strong adhesion for window adhesives applied to glass, ceramic silkscreen printing, lacquer, and metal surfaces. On bare metals, it acts as a reliable corrosion protection layer, preventing rust and ensuring long-lasting bonding.
Activator Properties
Würth Varioprimer also serves as an activator for trimming (remaining bead) and for use on PU/PVC pre-coated windows, ensuring clean bonding and optimum compatibility.

Application Instructions
Clean the bonding surfaces with an active cleaner.
Ensure all surfaces are dry, dust-free, and grease-free.
Shake the Varioprimer thoroughly before use.
Apply evenly using a primer brush or sponge applicator.
If using the 10ml tube version, do not apply pressure to the tube to ensure correct dosing.
Allow to flash off for a minimum of 10 minutes and a maximum of 72 hours (at 23°C and 50% relative humidity) before applying adhesive.
Safety and Usage Notes
Shake the bottle thoroughly before use.
Do not use if the primer has gelled.
Once opened, the product should be used as quickly as possible.
When applied to translucent surfaces (such as windscreens without screen-printed edges), additional UV protection for the adhesive surface is required to protect the primer.
