Substrates Timber Megapoxy 69 Gel Availlable in 1 Litre, 4 Litre and 20 Litre kits. When mixed, this product forms a cloudy gel which cures to a hard finish and is capable of bonding most materials of construction, including timber and metal (with proper pre-treatment). Megapoxy 69 Gel is used extensively in furniture manufacturing. Megapoxy 69 Gel is also available as a liquid (Megapoxy 69 Liquid) in 1 Litre and 4 Litre kits. You can add sanding dust to thicken the mix or disguise filled holes in timber. Megapoxy 69 can also be coloured with Megapoxy Epoxy Pigments. Epoxy Pigment Colours include: White, Black, Brown, Red, Yellow, Green, Grey and Beige.
Megapoxy HX Available in 4 Litre and 20 Litre kits Megapoxy HX is a very low viscosity clear liquid (and is therefore self-leveling). It can be used to fill feature holes, cracks and dents in character timber table tops. It is important to mix this product in the ratio specified (like all epoxies), which is 3:1 by volume. If you find the cure time is too long (particularly in winter, for example), you can use Megapoxy H Part B with Megapoxy HX Part A. Megapoxy H part B contains an accelerant which shortens the work and cure times.
Megapoxy PF Gel Available in 1 Litre, 4 Litre and 20 Litre kits. Megapoxy PF Gel is the fast version of Megapoxy 69 Gel. It has a 3-5 minute work time. The hotter the ambient temperature the shorter the work time. As with Megapoxy 69 Gel, the mixing ratio is 1:1 by volume. It is important to maintain this ratio, even though you may find that Part B has a lower viscosity relative to Part A. This means when you take a scoop of the Part A, it does not slump as much as Part B, and so some people add more Part B thinking that the scoop is not as large even though it has spread out on the mixing board. This results in a mixture that does not cure as hard as when it is mixed correctly. Megapoxy PF Gel is also available in a liquid form (Megapoxy PF Liquid) in 1 Litre and 4 Litre kits.
AVS XL Plus PVA AV XL PLUS Single Pack Crosslinking PVA provides excellent sandability with a clear, non-staining glue line. Ideal for furniture making purposes - edge gluing timber sections, solid timber bonding, veneers to core substrates, finger jointing, R.F. curing applications.
Concrete Megapoxy H- one of the many uses of Megapoxy H is a new to old concrete binder. In situations where concrete is being poured in a cold-joint, Megapoxy H or HT may be able to be used. Care must be taken that new concrete is placed before the epoxy has cured.
Glass There are several adhesives that will adhere to glass, however, if UV light will reach the bond line (i.e. the surface area between the glass and the adhesive, it is important to double check that this is within the tecnical specifications of the product (even where the product indicates it is UV stable)..
Plastics Plastics are harder to bond with adhesives relative to other materials. Within the different types of plastics, there are some that are are typically flagged - HDPE (High Density Polyethylene), PTFE (Polytetrafluoroethylene, also marketed as Teflon) and PP (Polypropylene) as being unsuitable to bond with chemical adhesives.
Given the particular adhesive challenge presented by plastics, surface preparation takes on greater significance and inadequate attention to this step may cause bond failure. Often, surface abrasion is specified prior to the application of the adhesive, this increases the surface area and mechanical key. Other processes may include wiping the surface with a solvent (such as acetone) to remove any surface contaminants (especially oily films such as that commonly found on stainless steel) and the use of a plastic primer.
If you consider cartridges and plastic nozzles, which are generally made from HDPE, after the product has cured, you can usually pull the material (silicone, polyurethane, SMP) off cleanly. The measuring containers that we use for mixing epoxies are made from PP and can often be reused after the epoxy has hardened because the epoxy pops out easily in one piece.
