Faq

Can Sika® Aktivator Pro Be Used In Damp Conditions?

• Yes, Sika® Aktivator Pro Can Be Used In Damp Conditions, E.G. On Windshields With A Light Misting Of Condensation. (In This Application, ‘Damp’ Refers To Any Humid Condition Where Larger Water Droplets Are Not Visible, Either As Pooled Condensation Or As Spots Of Rain). However, It Is Better If The Part Is Dried First.

If The Open Time Of Sika® Aktivator Pro Has Passed, Is It Ok To Perform The Activation Step Again?

• Yes. It Is Ok To Apply Sika® Aktivator Pro Up To Three Times Onto The Bonding Surface. It Is Important That The Surface Is Clean And Activated. You Can Tell If The Surface Has Been Activated When It Has A Shimmery Aspect To It. If You Are Uncertain It Is Better To Re-Apply Sika® Aktivator Pro.

Why Is The Use Of Daubers With Sika® Aktivator Pro Not Recommended?

• Sika® Aktivator Pro Performs A Cleaning Function, As Well As An Activating Function. Application With A Dauber Simply Moves Dirt Around And Does Not Clean It Off. Daubers Apply Too Much Product, Which Is Unnecessary And Wasteful.
• They Can Become Dirty And Contaminate The Activator If They Are Dipped In The Bottle Several Times.

Are There Any Aggressive Components In Sika® Aktivator Pro Or Sika® Primer-207 That Could Attack Surfaces?

• Sika® Aktivator Pro And Sika® Primer-207 Contain Reactive Components Which React Chemically With Glass, Paint And Other Materials. Once Cured, They Can Only Be Removed Mechanically And The Upper Layer Of The Substrate Is Damaged In The Process. Care Must Be Taken To Apply Sika® Aktivator Pro Only To The Required Areas. If The Product Is Applied To The Transparent Area Of The Glass, It Will Be Visible And The Customer Will Have Cause For Complaint.
