Innovative Pre-treatment Solutions

Sika offers a variety of pre-treatment solutions including black primers, activators, and cleaners, which are designed to improve immediate, as well as long-term adhesion on a very wide range of substrates.

Product Portfolio

Sika® Aktivator
Designed for direct glazing applications, Sika® Aktivator can be used on ceramic frits, glass float, and painted surfaces pre-treatments. Used as a standalone product or in combination with Sika Primer, it allows for primerless adhesion to paint and/or glass leading – a significant cost reduction which also helps reduce VOC emissions. Sika® Aktivator is also available as a very eco--friendly water-based solution as Sika® Aktivator Hydro. 

Sika® Primer
Our Sika® Primer direct glazing pre-treatment systems are widely used throughout the industry, but we also offer products that are specifically designed to support our OEM customers in achieving their weight reduction targets. For example, we offer a one-step, long open time black primer which can be used for pre-treatment of standard substrates like ceramic and paint, as well as plastics, carbon, aluminum, and other lightweight materials.

Our latest development is a multipurpose isocyanate based black primer with ultra-low free monomeric diisocyanate content.

Sika® Cleaner
Sika® Cleaner is used to remove potential contaminations – like dust, fingerprints, and silicone agents – prior to the application of Sika® Aktivator, Sika® Primer, and other pre-treatments. It also improves the immediate, as well as long-term, stability of the adhesion.
