NOVABOND®

Instructions for use – surface preparation:
Clean the surface to be treated well. TECHNOSOL® should be used for degreasing. Roughen the surface thoroughly up to pure metal (by grinding or sanding). We recommend making holes bigger or broader when repairing small defects or micro porosity, for example, cut a V-shaped groove when repairing fissures in cracks. Bigger holes guarantee perfect anchoring, and thus obtaining reliable strength.
Clean the surface with TECHNOSOL® again before NOVABOND® is applied.

Instructions for use – puttying:
Mix both ingredients (A and B) in the plastic container because of possible sedimentation before the preparation of the NOVABOND ® mixture. The mixing ratio of NOVABOND® ingredients is 2 : 1 (2 units of A and 1 unit of B). Mix both ingredients thoroughly (2-3 minutes) in the given ratio and apply them to the place to be repaired. Processability time is about 15 minutes. The surface can be smoothed using a wet spatula or another tool after withering to obtain a perfectly smooth surface. When puttying deep holes, putty must be applied in layers to be compacted using a suitable tool. Time for hardening depends on temperature and the thickness of the layer. A thinner layer is hardened in a longer time, a thicker one hardens more quickly. The NOVABOND ® is hardened after about 4 hours after mixing at 22 °C. The minimum temperature for application is 5 °C; however, it prolongs the duration of the hardening process considerably. We recommend applying a thicker layer of the putty, processing it after full hardening (about 24 hours). To obtain better properties, the material can be gradually heated up to the temperature of about 80 °C during 4–24 hours (forced hardening) after having reached the manipulation strength. This causes perfect molecule networking (interconnecting) and complete hardening of the material. This improves the resulting hardness, thermal and chemical resistance.
