Product description
Sikaflex-295 UV is a one-component polyurethane adhesive and sealant specially developed for bonding plastic glazing in marine applications. This paste-like sealant cures by reacting with moisture in the air, forming a durable, elastic bond. Sikaflex-295 UV is ideally suited for both interior and exterior sealing applications. It complies with international marine regulations of the International Maritime Organization (IMO) and is Wheelmark approved.
Benefits of Sikaflex-295 UV adhesive and sealant
- Suitable for plastic glazing (such as acrylic/Perspex® or polycarbonate/Lexan®) on boats and ships.
- Resistant to weathering and ageing.
- Good application properties.
- Approved for use by OEMs (Original Equipment Manufacturers).
- Wheelmark-approved.
Applications
Sikaflex-295 UV has been specially developed for the marine industry, where it is used for bonding and sealing plastic glazing on boats and ships. Thanks to its excellent weather resistance, it is also highly suitable for sealing joints exposed to weathering. Sikaflex-295 UV adheres well to a wide range of substrates, including aluminium (bare or anodised), GRP (glass-fibre reinforced plastic), stainless steel, wood, two-component coatings, and plastics such as polycarbonate (PC) and acrylic (PMMA). Always carry out adhesion and compatibility tests on the intended substrates under local conditions before use.

The recommended application temperature range indicates the conditions under which the product can generally be applied and cured properly. Three temperatures matter:
- Air: the temperature in the workshop or outdoors.
- Substrate: the temperature of the surface being treated.
- Product: the temperature of the resin, adhesive or coating itself.
A cold substrate can cause condensation and affect adhesion. At higher temperatures, two-component products may react faster, reducing their working time. Check the dew point and follow the product instructions.
- 10-35 °C
-
The chemical base describes the chemistry of an adhesive, sealant, resin or coating, such as epoxy, polyester, polyurethane, (methyl)methacrylate or a hybrid polymer. It affects curing, flexibility and adhesion. Products with the same chemical base are not necessarily suitable for the same applications.
- One-component polyurethane (PU)
-
The period for which an unopened product remains usable under the specified storage conditions. Check whether the period starts from the manufacturing date or another date. Shelf life may be shorter after opening, especially for products sensitive to air or moisture.
- 12 months
-
The time after application during which a skin forms on the surface of a sealant. Tool the joint before the skin develops, as adjusting it afterwards can affect the finish or adhesion. Temperature and humidity influence this time.
- 1 hour
-
Open time is the period during which an applied adhesive, sealant or mortar can still be assembled, positioned or adjusted. It is usually given in minutes under specified conditions, often around 20 or 23 °C. Open time generally starts at application and may differ from the working time after mixing.
- 45 minutes
-
Elongation at break indicates how much a material can stretch during a tensile test before it breaks. It is expressed as a percentage (%) of the original length. At 100% elongation, the material has doubled in length just before breaking. A high value indicates a high ability to deform, but not how much force is needed.
- 500%
-
Sag resistance describes how well a paste, sealant or coating stays in place after application without running or slumping. It matters on vertical surfaces, in thick adhesive joints and for overhead repairs.
A product may be thixotropic: it becomes easier to work when stirred or spread, then thickens again at rest. This makes application easier without the material immediately running down the surface. Sag resistance is not the same as viscosity; behaviour after application also matters.
- Good
-
Tensile strength is the maximum tensile stress a material can withstand during a tensile test before failure. It is usually expressed in MPa (megapascals) or N/mm² (newtons per square millimetre); 1 MPa = 1 N/mm². Under comparable test conditions, a higher value means greater resistance to tension. In composites, fibre orientation also affects the result.
- 2 MPa
-
The curing mechanism explains how a product develops its final strength or shape. The main mechanisms are:
- Two-component reaction (2K): a chemical reaction begins once components A and B are mixed. Mixing ratio and working time are important.
- Moisture curing (often 1K): the product reacts with moisture in the surrounding air. Temperature, humidity and film thickness affect the process.
- UV curing: light of the appropriate wavelength triggers the reaction. Areas that are not exposed to the light may not cure fully.
- Physical drying: water or solvent evaporates. This is different from chemical curing.
Some products use more than one mechanism, so the correct application conditions depend on the particular system.

Heat resistance describes the temperature a material can withstand after correct processing and curing, usually expressed in degrees Celsius (°C). Continuous exposure is different from a brief temperature peak, and mechanical loading may also affect the limit. Heat resistance is not the same as the temperature at which the product can be applied.
- -50 to 90 °C
