Clear, very fast curing, two-component, high-strength epoxy adhesive resistant to fuels, solvents and vibrations; easy to sand after fully cured. It does not become brittle with age. Bonds wood, glass laminate, carbon composites, aluminum, copper, steel, brass, concrete, glass, hard plastics, polystyrene foam, etc.

Properties

Mixing ratio of ingredients: 1:1 (by volume and weight)
Initial color: clear
Final color: clear
Viscosity (after mixing): 5000-10000 mPa.s
Working time (until gelling): approx. 5 min (20 °C to 25 °C)
Glued parts can be handled: after 15-20 min
Half strength: after 10-15 min
Full strength: after 2-3 hrs
Full curing: 16-24 h
Shear strength: 20 N/mm²
Temperature resistance of the glued joint: -40 °C to +120 °C
To remove excess uncured glue: a cloth or paper towel moistened with denatured alcohol.

Thinning the adhesive: S6300 Epoxy Thinner (use of thinners increases curing time and reduces final bond strength - if you need a "thinner" epoxy, use a lower viscosity laminating or finishing epoxy).

Use as a sealant, suitable fillers: microballoons, talc, baby fill, diatomaceous earth, fine balsa or linden sawdust, chopped glass fibers. Attention - the addition of filler can reduce the working time by up to 25% and (depending on the type and amount of filler used) can reduce the strength of the joint.

Suitable for bonding: soft and hard wood, chipboard, plywood, metals, polystyrene foam, ceramics, porcelain, glass and carbon laminates, glass and carbon fabrics and fibers.

Not suitable for gluing: soft and flexible plastics (including EPP and EPO), polyethylene, Teflon.

Storage: in a tightly closed container, in a cool, dry and dark place (at a temperature of 10 °C to 25 °C). Do not expose to temperatures below 10°C. Be careful not to mix up resin and hardener caps - even a small amount of hardener can spoil a large amount of resin.

Durability: under proper storage conditions, we guarantee a shelf life of 1 year while maintaining the above product features. Practical experience shows that epoxy resins based on bisphenol A and epichlorohydrin retain their excellent properties for many years when properly stored (see also Note 2) - if you buy a package of glue appropriate for your consumption, you practically do not have to "solve" its lifespan at all.

Note 1: the curing of the adhesive depends mainly on the ambient temperature; if you mix a large amount of epoxy at once (typically more than 20-30 g) it can harden much faster - to maintain a longer working time, the glue needs to be cooled in a water bath, for example. This is because heat is released when the resin and hardener react, and at the same time, the resin cures faster at a higher temperature. And since as the volume increases, the weight of the resin (and therefore the amount of heat generated) increases faster than the size of the external surface from which the heat is dissipated to the surroundings, more resin heats up and hardens more quickly. Don't you believe? Believe. A cube with a side of 1 cm has a volume of 1 cm³ and a surface area of 6 cm² - a ratio of 6:1, while a cube with a side of 2 cm has a volume of 8 cm³ and a surface area of 24 cm² - a ratio of only 3:1.

Note 2: initially clear and fairly fluid bisphenol A and epichlorohydrin-based epoxies can sometimes thicken ("sugary" much like honey bees) and lose transparency - this is due to exposure to low temperatures, moisture or time. By carefully heating in hot water (60-70°C) for a few minutes until the resin becomes clear again throughout the volume, you will get a "like new" resin with its original properties.
