Sika® Aktivator 100 is a special solution of cleaning solvents and adhesion promoters.
Use it to pre-treat surfaces prior to using Sika Primers, as Aktivator 100 will make the primers adhere better to the substrate.
Although in certain applications primers are highly recommended, or even required, Aktivator 100 may also be used alone as a pre-treatment for any Sikaflex® polyurethane adhesive sealant to enhance its bonding and long-term performance — by years, in many cases. Well worth the price...
Compared to the similar Aktivator 205, Aktivator 100 is the preferred choice for a somewhat larger range of substrates, but there is a high degree of overlap between these two Aktivators — so in many cases either one can be used. See below for more details.
Some substrates for which Aktivator 205 is preferred, however, include rolled coatings, hard PVC and possibly ABS plastics.
Of special note...
• When bedding mineral glass windows — you MUST use Aktivator 100 as a pre-treatment (followed by Primer 206 G+P, and then Sika 296 adhesive sealant for glass).
• When bedding plastic windows, hatch lenses, or portlight lenses (acrylic/Plexiglas® or polycarbonate/Lexan®) — you MUST use either Aktivator 100 or Aktivator 205 (followed by the preferred Primer 209 D, and then Sika 295 UV adhesive sealant)
Alternately, if it's the only primer you have on hand, you can use Primer 206 G+P on plastic windows, but in this application it must be pre-treated only with Aktivator 100.
A little more detail and some application tips...
Although good, or even excellent, results can be achieved by applying polyurethane adhesive sealants directly to substrates, some applications will benefit significantly from pre-treatment with Aktivators 100 or 205 before applying the adhesive sealant. (Wood is an exception.)
Pre-treating with Aktivator 100 is especially recommended for improved adhesion and weather resistance when bonding or sealing:
• Metals - stainless steel, aluminum, and powder-coated metals
• Many plastics - ABS, fiberglass
• Many types of paint and lacquer finishes
Using Aktivators 100 or 205 typically leads to a more tenacious bond — both initially and years later, after continued exposure to sun, moisture, and temperature extremes.
With most substrates, scuffing the surface with an abrasive pad will yield even better results.
For critical applications and all glazing, Aktivator 100 or 205 should always be followed by the use of a substrate-appropriate primer before applying your adhesive sealant. (See below for more details.)
Some dos and don'ts:
• Aktivators 100 or 205 are required as a pre-treatment in virtually all applications where any Sika Primer is used (wood is an exception)
• Do not use Aktivator 205 or the automotive industry Aktivator PRO as a substitute for Aktivator 100 in marine mineral glass applications; use only Aktivator 100 (with the orange cap)
• Do not use either Aktivator 100 or 205 on porous surfaces
• Aktivators 100 and 205 will not aid adhesion to UHMW, polyethylene, polypropylene, nylon, or other low surface energy (water beads up) surfaces
Note: The color of Aktivator 100 can vary from very light amber to dark amber; this has no significance as far as age or quality goes.
• When using Aktivators 100 or 205, wipe on a thin layer, then wipe it off with a dry towel and let it react for at least 10 minutes to allow adhesion promoters to work, then apply your primer or adhesive sealant
• Open range to apply adhesive or sealant is 10 to 120 minutes; Aktivators 100 and 205 can be re-coated if you miss your application window
• Shelf life is 12 months in unopened container
When applying adhesive sealants in critical applications, it is important to take into account the type of surface being bonded, as well as the surface being bonded to. You may decide to use one primer system for one, and a different primer system for the other.
For more specific information about bonding various materials and substrates, we urge you to refer to Sika's Primer and Pre-Treatment Charts for detailed substrate-specific information.
Especially, read over the explanatory notes for individual substrates on page 4 of the chart.
NOTE — The linked webpage, above, opens with Chart #1 (Hybrid/500 series) pre-selected for downloading by default (the colored icon).
For applications using common Sikaflex 200 series products (291, 295 UV, etc.), you will need to switch to, and open or download, Chart #2.
On these Primer Charts, column 1 contains recommendations for non-critical applications, and column 2 is for critical applications. Within each substrate type, the first/higher recommendations are preferred.
Note that substrate PMMA/PC represents plastics such as acrylics and polycarbonates.
Heavy on the technical side...
Sika Aktivators and Primers cure via exposure to moisture in the air (humidity).
Once opened, the cap should be replaced after each use. Do not leave the can open unless you are actually using it.
With frequent use i.e. opening and closing several times, Sika recommends disposing of the product one month after opening. With infrequent use, Sika recommends disposing of the product 2 months after opening.
If the Aktivator in the can turns cloudy or does not pour like water, it has been exposed to excessive moisture and should be replaced.
Sika Aktivators are manufactured in accordance with ISO 9001/14001 quality assurance system and the Responsible Care Program.
Sika has published a number of excellent technical "how to" documents for common marine applications using their Aktivators, Primers, and Adhesive/Sealants.
Topics covered include bedding and sealing hardware, rub rails, plastic windows, mineral glass windows, wood, UV exposure issues, etc.
