Jotatop LEP Tiecoat
This is a modified two-component polyaspartic ester coating. It is a fast-dry product with good adhesion. Used as a tiecoat in the leading edge area of wind turbine blades. Developed to improve the adhesion of Jotatop LEP Pro on various substrates, such as glass/carbon fiber reinforced epoxy and/or polyester composite substrates, and other primers or topcoats, such as Jotatop BC100 and Jotatop BC300WF. Jotatop LEP Tiecoat must be applied in the leading edge protection area before Jotatop LEP Pro.

Surface Preparation
| Substrate | Minimum | Recommended |
| Coated surface | Clean, dry and intact compatible primer. Mechanically sand the surface with P80–P240 grit abrasive paper to form a uniform scratch profile. | |
| Composite | Surface preparation shall commence only after the composite material has fully cured. Sand the surface by hand or power tool with P80–P120 medium to fine abrasive paper made of non-metallic abrasive or fiber material to produce a scratch pattern on the surface. | |
This product may be applied by the following methods
| Spray: | Use conventional spray. |
| Brush: | Recommended. Use high-performance natural-material brushes (e.g. badger hair or ox hair). Ensure the specified dry film thickness is achieved. |
| Roller: | Recommended. Use short-nap or flocked foam rollers to achieve good flow and levelling and reduce surface orange peel. |

In some markets, the stated shelf life may be shortened to comply with local legal requirements. The above is the minimum shelf life; thereafter, testing is required to confirm quality remains acceptable.
For professional use only. Applicators and workers must be trained, experienced, capable and equipped to mix, stir and apply the coating correctly in accordance with JOTUN's technical documents. Applicators and workers must wear appropriate personal protective equipment when using this product. This guidance is provided based on current product knowledge. Any proposed modification to suit site conditions must be approved by the responsible JOTUN representative before use.
Read the safety warnings on the container packaging. Use in well-ventilated conditions. Avoid inhaling spray mist and avoid skin contact. In case of accidental splashes on skin, wash immediately with a suitable cleaner, soap and water. In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
The information in this datasheet is based entirely on knowledge gained in our laboratory and in practice. JOTUN products are regarded as semi-finished products, and their use is generally beyond our control. JOTUN therefore guarantees only the quality of the product itself.
