Abatron ROCKWELD 55-27 A/B Structural Adhesive Putty; Epoxy
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: ROCKWELD 55-27 is a 2-component epoxy system with low density, high-strength, and no shrinkage. It is a structural adhesive putty for sculpturing, repairs and restoration of stone, concrete and masonry, terracotta, and ceramics. This clay-like putty can be used to build up, model, patch, or replace shapes or parts of any structural or decorative element. Statues, architectural decorations, ornaments and mosaics can be repaired and restored using ROCKWELD. Broken stairs, railings, cracked and splitting concrete patios, floors, and walls are only a few examples of ROCKWELD applications. Tenacious adhesion to metal and wood also allows the repair of items made of different materials. The clay-like putty hardens without shrinking. It can be built up several inches thick. Thicker layers can generate too much heat that may impair final properties of the material. The new material adheres permanently to the old one. ROCKWELD can be shaped by hand because of its modeling clay consistency. It does not slump or sag when being applied to vertical surfaces. After hardening this material can be sanded by hand using coarse sandpaper (100 grit or less) or any mechanical tools such as circular or belt sanders. Tools like knives or files are not recommended because of the high abrasiveness of ROCKWELD. ROCKWELD can be primed and coated using any solvent or waterborne paint. Slight sanding is recommended, in some cases, as a surface preparation. To match the color of the object to be repaired, any dry pigment or pigment dispersion compatible with epoxy systems can be admixed to ROCKWELD. It can be blended with pebble stone, gravel, or concrete particles. It can be reinforced with inserts, rods, wires, and other reinforcing elements. ROCKWELD is chemically resistant and unaffected by atmospheric conditions and soft and salt water. ROCKWELD bonds to wet as well as dry surfaces.
