About this deal

This fast curing Epoxy Metal Filler is suited to repair car surface damage to metal parts such as dents, reshaping of surfaces or fully sealing welded seams to provide corrosion protection. 3M™ FC Epoxy Metal Filler has a unique formulation, is lead-free, contains 100% solids and thus will not shrink whilst curing. It shows excellent adhesion and corrosion protection properties. Material hardness and strength depend on alloy composition and heat treatment (solution heat treatment and quenching followed by either natural or artificial ageing produces a fine dispersion of the alloying constituents). Principal alloying elements are defined in the 2xxx, 6xxx and 7xxx series. Fusion welding redistributes the hardening constituents in the HAZ which locally reduces material strength. Processes

Aluminium and its alloys can be readily welded providing appropriate precautions are taken. The most likely imperfections in fusion welds are: Dipping, spraying or wiping with organic solvents can be used to remove grease, oil, dirt and loose particles. Hi-Temp Lab-metal is applied directly from the can with a putty knife or similar tool. No two-component mixing or measuring is necessary. Many applications may be made from a single can. After each use, to prevent Hi-Temp Lab-metal from hardening in the can, pour Lab-solvent over the remaining Hi-Temp Lab-metal contents, then cover tightly. (Stir the solvent into the Hi-Temp Lab-metal before using again). Lab-solvent is also used to thin Hi-Temp Lab-metal for brush-on applications. You may be astonished after reading all these considerations because it looks strange that a simple tube of glue can have so many instructions and research behind it. However, if you get more informed, your choice will be more thoughtful. You will not waste your time and money on something completely useless for your needs. As pure aluminium is relatively soft, small amounts of alloying elements are added to produce a range of mechanical properties. The alloys are grouped according to the principal alloying elements, specific commercial alloys have a four-digit designation according to the international specifications for wrought alloys or the ISO alpha - numeric system.Material strength depends on the effect of work hardening and solid solution hardening of alloy elements such as magnesium, and manganese; the alloying elements are mainly found in the 1xxx, 3xxx and 5xxx series of alloys. When welded, these alloys may lose the effects of work hardening which results in softening of the HAZ adjacent to the weld. Heat-treatable alloys It is recommended that the powder is mixed thoroughly with Part 'A' of polyurethane casting resins (like our Fast Cast) before adding part B. Never count the weight of the filler powder in the mix ratio.

A spool gun or push-pull gun for the MIG welding process. These guns provide consistent feeding of the aluminum filler metals, minimize wire feeding issues and allow for welding further distances from the wire feeder (often as far as 30 feet away). To minimise the risk, rigorous cleaning of material surface and filler wire should be carried out. Three cleaning techniques are suitable; mechanical cleaning, solvent degreasing and chemical etch cleaning. In addition to proper selection, storage and handling with 4043 and 5356 filler metals — or any aluminum filler metals for that matter — it is important to have the right welding equipment for the job. This equipment includes: Applications where aesthetics are particularly important, since these filler metals provide bright, clean welds.The choice of filler metal composition for the various weldable alloys is specified in BS EN 1011 Pt 4:2000 for TIG and MIG welding; recommended filler metal compositions for the more commonly used alloys are given in the Table. Alloy Designation Applications where distortion is of particular concern, as it minimizes this defect.
A 5356 aluminum filler metal would be most appropriate for:

That is why we have collected some factors that you have to take into consideration while choosing the right epoxy for your purposes. Here they are. Time for Drying Aluminium trihydroxide is an inert, odourless filler powder than can be used to reduce shrinkage and add weight to cast polymer products. It can also improve the fire resistant properties of the casting and reduce exothermic reaction. Hi-Temp Lab-metal is recommended where original Lab-metal may not withstand the extreme heat. Originally developed due to requests from the foundry industry, industries such as metalworking, powder coating, welding, fabricating, heating, construction, auto repair, die casting, mold refinishing, and sheet metal production and finishing have found uses for Hi-Temp Lab-metal. It successfully repairs: Thin with Lab Solvent to ease spreadability. Typically dries in 24 hours, heat cure at 425 degF for 1 hour before exposing to high temperatures. Great for filling surfaces before powder coating where 2 or more coats are required.Yes, marine epoxy is designed to adhere to aluminum. It forms a strong bond that can withstand extreme weather conditions and harsh environments. However, it’s important to make sure the surface of the aluminum is properly prepared for the epoxy application. Before applying, you should clean the aluminum with a solvent or degreaser, then lightly sand or chemically etch it. This will ensure the best possible adhesion between the epoxy and aluminum. Additionally, make sure you select an appropriate type of marine epoxy for your project – some are better suited for specific applications than others. With proper preparation and selection of epoxy, you can trust your repair job will last for years to come. What can you put on aluminum to keep it from corroding? You need to know the conditions in which your repaired surface is supposed to function. Consider the highest and lowest temperatures possible. Sometimes, that can become a critical indicator. Overall Look and Ability to Be Painted Aluminium trihydroxide can be added to casting resins at an approximate maximum percentage of 200% by weight (e.g. 200g of filler powder to 100g of resin). Doing so will reduce shrinkage, improve thermal stability considerably and result in a heavier more substantial feel to cast products however the resin will become harder to pour and reproduction of fine surface details will be impaired as the filler content is increased.
