Serabond #15 UV-Resistant Outdoor Sewing Thread, Tex 210, V207
Need a heavy-duty thread for outdoor and technical textile sewing? Serabond Size #15, Tex 210, V207 is a bonded sewing thread specified for outdoor use. Its bonded construction helps the thread feed consistently and resist untwisting during sewing, while its UV-resistant specification makes it a suitable choice for projects exposed to sunlight. Each cone contains 2,400 metres of thread with a stated diameter of approximately 0.46 mm.
Suitable applications
-
Awnings, canopies and shelters: for sewing outdoor fabric assemblies and covers.
-
Outdoor covers and equipment: for projects where a durable bonded thread is specified.
-
Sails and technical textiles: for suitable materials and machines set up for this thread size.
Choose the needle, machine, stitch and tension to suit the fabric and thread size. UV resistance does not mean a finished seam is immune to sunlight, abrasion, moisture or wear; service life depends on the material, construction and conditions of use.

Potential failure causes to check
These are general sewing and service-life risks, not claims that this thread is defective:
-
Thread breaks or frays during sewing: a needle that is too small or damaged, incorrect tension, rough guides, or a machine setup unsuited to a heavy thread can contribute.
-
Seam damage in use: abrasion, sharp edges, excessive load, or unsuitable fabric and stitch construction can wear or break stitches.
-
Strength or appearance deteriorates over time: prolonged exposure to sunlight, heat, moisture, dirt or chemicals can affect thread and seam life despite the UV-resistant specification.
If breakage starts, check the needle, threading path, tension and machine compatibility before replacing a cone.
Storage and spare-thread guidance
Store cones in a clean, dry, cool place, protected from direct sunlight, heat, moisture, dust and chemical fumes. Keep the thread covered in its packaging when not in use, and avoid leaving cones in a hot vehicle or exposed workshop area.
There is no reliable fixed replacement interval without knowing your workload and conditions. Replace a cone if it is contaminated, visibly damaged or discoloured, feels brittle, or continues to break after the machine setup has been checked. For a production machine where a pause would disrupt work, keep one spare cone in the same colour on hand; for occasional use, one shared spare per regularly used colour is a practical starting point. Match colour and, where possible, batch when seam appearance matters.
