  • Good gap-filling properties
  • Can be painted
  • Bonds well to a wide variety of substrates

Areas of Application:

Sikaflex-292i is suitable for structural joints in marine constructions which will be subjected to high dynamic stresses. It is suitable to bond metals, particularly aluminum (including anodized finishes), metal primers and paint coatings (2-component systems), or ceramic materials, plastics such as GRP (unsaturated polyester resin), ABS, etc. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex-292i on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.


  • Good gap-filling properties
  • Can be painted
  • Bonds well to a wide variety of substrates
  • Wheelmark approved
  • Solvent-free and very low VOC

Surface Preparation:

Surfaces must be clean, dry, and free from grease, oil, and dust. Surface treatment depends on the specific nature of the substrates and is crucial for a long-lasting bond. Suggestions for surface preparation may be found on the current edition of the appropriate Sika Pre-treatment Chart.

Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates.


Sikaflex-292i can be processed between 10 °C and 40 °C (climate and product) but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and sealant is between 15 °C and 25 °C. Consider that the viscosity will increase at low temperatures. For easy application, condition the adhesive at ambient temperature prior to use.

Tooling & Finishing

Tooling and finishing must be carried out within the skin time of the sealant. It is recommended to use Sika Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior to the use.


Uncured Sikaflex-292i can be removed from tools and equipment with Sika Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using Sika Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water. Do not use solvents on the skin.

Nomadic Supply Company Freight Versus the Big Box Stores

Nomadic Supply Company wants you to receive your valuable products in absolutely pristine condition so we ship our large refrigerators via truck freight, and we handle and package them in a way that no other retailer does.

When we prepare refrigerators for shipment we spend a full hour to inspect, re-pack, prepare, and schedule your truck freight shipment for the following day. This process ensures that your order arrives to you completely undamaged and in brand new condition. Our competitors do not do any of this for you, and they are are infamous for having their refrigerator shipments arrive damaged.

Our detailed inspection and repacking process will cause a minor delay in shipping your order to you, but unlike all of the other online stores, our shipments actually arrive to you in one piece, without damage, every single time.

  • → We inspect, repack, & double or triple box refrigerators in our custom made, dual wall, fully overlapped, 450lb. test-rated boxes.
  • → Nomadic Supply Company adds 2” Styrofoam and reinforcements to the packaging and all of the large refrigerators are fully palletized.
  • → We take photos of your shipment before, during and after your order is completed. Our customers LOVE this!

We do not recommend residential deliveries via truck freight:

Residential deliveries are always more expensive than shipping to the closest freight terminal. Shipping to the closest truck freight terminal in your area has numerous advantages over shipping to your residence:

  • → It saves you a ton of money in truck freight fees, usually around 50%.
  • → You can schedule to pick the shipment up at your convenience rather than spending a full day at home waiting for it.
  • → You can thoroughly inspect your shipment for potential damage caused by the freight carrier before accepting & signing for it.

You must read and understand the entire LTL Freight process if you want to order a refrigerator from Nomadic Supply Company.
