TASK
Adhesion test with Sika® products on the submitted samples.
SUMMARY
1. Adhesion test
Test results show that the adhesive system below can achieve good bonding effect:
Sample: Misty lvory Lime stone
IPA + Sikaflex®-11FC Grey
IPA + Sika® Primer-210 + Sikaflex®-11FC Grey
REMARKS
The results only apply to the tested quality.
Constant/reproducible surface quality is required.
Any changes can result in adhesion loss.
Direct contact between Sikasil® and SikaHyflex® products with sulfur curing gaskets is not approved.
Surface pre-treatment always includes surface cleaning as first step (cf. para. "Method of Application" in the
relevant Product Data Sheet) and application of adhesion promoter as second step.
Compatibility test methods are based upon valid standards, RAL as well as other guidelines.
Compatibility test results between non-Sika materials and Sika sealants and adhesives are generally batch-related,
since Sika has no control over the manufacturing process of third-party products.
Nevertheless, the results may be transferred to other batches as long as it can be ensured that the formulations,
the raw materials, the production process or other important parameters which may influence the compatibility
are not altered.

The test results are analyzed as shown in the Tables below:
Note Assessment Bond
1 Bond satisfactory > 95% cohesion failure
2 Bond basically satisfactory > 75% cohesion failure
3 Bond not satisfactory > 25% cohesion failure
4 Bond not satisfactory < 25% cohesion failure
5 Bond not satisfactory 0% cohesion failure
Additional rating for the adhesive Rating of mixed rupture mode
Index Assessment
TU Tunnel effect/edge bonding
UC Adhesive is not fully cured
SCF Substrate close cohesive failure (substrate visible)
FS Foam structure on the bond surface (fine bubbles)
BA Bubbles in adhesive
ES Edge separation
NT Not tested
Additional rating for substrates
Index Assessment
BS Bubbles/voids on the substrat's surface
SF Substrate failure (failure in fibers or layers of non-coated substrates
CR Chipping of the coating (paints, etc)
PR Rupture in the primer
Cor Corroded substrate
PT Partial adhesion loss of primer to substrate (tunnel)
Note:
If no additional designation is given, the failure area (for adhesive failure) is between the adhesive and the layer applied last. Different failure
modes should be described.
