How can I remove synthetic resin?
Synthetic resin, a versatile material
Synthetic resin is a versatile modern adhesive that is used, for example, in boat building, in the home, and in model making. In combination with glass fiber, carbon fiber, and aramid fiber, it is used as a fiber-reinforced plastic in the construction of modern gliders, but also increasingly in large passenger aircraft. Synthetic resin is also used in the production of stone carpets, as a casting resin for the manufacture of components in the casting process, for industrial floors, concrete coatings, and concrete repairs. Epoxy resin is also used as corrosion protection (steel structures), in the renovation of pipes (e.g., underfloor heating) and in the sealing of terrariums, as it is non-toxic when cured. But how do you remove it?
During processing, fresh splashes or residues that have not yet hardened can be removed with acetone and a cleaning cloth. Hardened synthetic resins are best removed mechanically, by sanding with sandpaper or using a sander. It is essential to pay attention to the heat generated depending on the substrate layer in order to avoid damage to the material and the latent fire hazard. When sanding plastics as a substrate, special care must be taken; often, only roughening the surface is possible in order to reapply synthetic resin. If synthetic resin has seeped into joints, small depressions, or porous surfaces such as wood, removal is no longer possible. If the substrate is heat-resistant (e.g., steel), it can be heated with a hot air gun and the gelatinous synthetic resin can then be removed with a spatula, which is very laborious. Here, too, particular attention must be paid to heat development and the latent fire hazard.
PROTECT YOURSELF!
Wear gloves, safety goggles, a respirator, and protective clothing when performing any work. Heating (including sanding) can produce fumes; a dust mask is not sufficient protection. Uncured residues are hazardous waste. When working with resins, observe the information in the safety data sheets!
