PA Knofiller is based on a flexible POLYAMIDE- mixture. The concept has been used successfully for over two decades, because it serves the high demands of wood repair perfect.
PA Knotfiller repairs are characterized by strength and high level of flexibility. Therefore repair spots by PA knotfiller remain in the wood withaout cracking or shrinking.
The great advantage in comparison to 2-component fillers: Advantages as ASTFÜLLER
| PA Knot filler | 2-component fillers |
| 😉 Absolutely harmless without any worries | 🙁 Toxic solvents diffuse |
| 😉 Cures – depending on the repair size and ready for further processing steps in a few seconds | 🙁 Requires a certain curing time and so you need a temporary storage |
| 😉 Immediately usable and workable at any time (if necessary) | 🙁 Components have to be mixed in a certain ratio |
| 😉 16 colours in the standard range – special colours on request | 🙁 Limited colour availability |
| 😉 Pinpoint repair and hardly no remains | 🙁 Remains, which hasn´t been consumed can´t be used (up to 50%) |
| 😉 To process without problems | 🙁 Solvent diffusion during further processing |
| 😉 Easy to use with a hot glue gun | 🙁 Inaccurate mixture ratios leads to reduce the quality |
| 😉 Repair of large damages without shrinking or getting cracks | 🙁 The brittle material components can shrink or get cracks |
| 😉 Up to 5 times higher economicalness | 🙁 Additional loss of material by reusable remains |
| 😉 Up to 5 times higher repair times compared to alternative repairs | 🙁 In case of jerky loads the brittle and inflexible repairs can fall out |
| 😉 UV stabilized | 🙁 You have to examine the UV resistance |
| 😉 Suitable for further surface treatments, such as stains, oils, varnishes, etc. | 🙁 Surface treatments are only possible to a limited extent |
| 😉 Absolutely perfect for complicated repairs f.e. edges, corners and loose knots | 🙁 Complicated repairs are only possible to a limited extent, because the 2-C fillers have a brittle nature |
