Note: The designer of the process system must be aware that all applications, including mesophilic and thermophilic digestion, are dependent on pH and content analysis which must be addressed at the specification phase.
Service Temperature
| Dry | -40 °C min. / +70 °C max. |
| Wet | ≤ 40 °C in movement joints ≤ 55 °C* as overlap sealing in bolted steel tanks |
* Continuous maximum service temperatures are subject to the behaviour of chemical mixtures, which can be complex. The designer of the process system must be aware that all applications, including mesophilic and thermophilic digestion, are dependent on pH and content analysis which must be addressed at the specification phase.
Joint Design
The joint dimensions must be designed to suit the movement capability of the sealant.
The sealant must only be subjected to stress and chemical exposure after full curing to prevent reducing adhesion and performance.

SUBSTRATE PREPARATION
The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles.
For optimum adhesion and joint durability, the following substrate priming (and/or pre-treatment) procedures must be followed:
Non-porous substrates
Enamelled steel, aluminium, anodised aluminium, stainless steel, galvanised steel, powder coated metals or glazed tiles. Slightly roughen surface with a fine abrasive pad. Clean and pre-treat using Sika® Aktivator-205 applied with a clean cloth.
Before sealing, allow a waiting time of > 15 minutes (< 6 hours).
Consult the tank manufacturer's instructions for their specific preparation and priming recommendations.
Other metals, such as copper, brass and titanium-zinc, clean and pre-treat using Sika® Aktivator-205 applied with a clean cloth. After a waiting time of > 15 minutes (< 6 hours). Apply Sika® Primer-3 N applied by brush. Before sealing, allow a waiting time of > 30 minutes (< 8 hours)
PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. Before sealing, allow a waiting time of > 30 minutes (< 8 hours).
Porous substrates
Concrete, aerated concrete and cement based renders, mortars and bricks surfaces must be primed using Sika® Primer-3 N applied by brush.
Before sealing, allow a waiting time of > 30 minutes (< 8 hours).
Adhesion tests on project specific substrates must be performed and procedures agreed with all parties before full project application.
Note: Primers and activators are adhesion promoters and not an alternative to improve poor preparation / cleaning of the joint surface. Primers also improve the long term adhesion performance of the sealed joint.

CLEANING OF TOOLS
Clean all tools and application equipment immediately after use with Sika® Thinner C. Hardened material can only be removed mechanically. For cleaning skin, use Sika® Cleaning Wipes-100.
