Epoxy Resin HT 2
General information about the system Epoxy Resin HT 2 + Hardener HT 2
Solvent- and filler-free, transparent laminating and coating system of very low viscosity with tack-free, glossy surface.
- Highly transparent, very light, max. slightly reddish in thicker layer
- High degree of UV stability
- Tack-free curing even of thin layers
- Also for casting in layer thicknesses up to 5 mm in one operation
- Free of nonylphenol
Epoxy Resin HT 2 is suitable for impregnating glass, aramid, and carbon fibres* and for bonding wood, metal, foamed polystyrene, etc..
*Owing to its low surface tension the system exhibits good filler absorption properties. And it has excellent wetting properties with respect to reinforcing fibres of glass, aramid, and carbon.
Epoxy Resin HT 2 is a laminating resin of very low viscosity based on bisphenol A/F. The bisphenol F component reduces the viscosity and prevents the resin from forming crystals at low storage temperatures (less than + 5 °C).
Epoxy Resin HT 2 is diluted with a difunctional reactive compound and is free of solvents and fillers.
The system is highly transparent and yields in conjunction with finished glass fabrics (Finish FK 144/FK 800) highly transparent laminates with
good light fastness.

CYTOX Report on the Resin System Epoxy Resin L + Hardener L (see below under Additional Information): this system is not cytotoxic (cell-damaging), important for applications in medical technology.
Application:
Highly transparent, water-resistant laminates, above all for surfboards, snowboards, boat linings, aquarium accessories, light domes, solar cell coatings, floor finishes.
The Epoxy resin HT 2 is suitable for all common processing methods, e.g. hand lay-up operations, pressure and vacuum impregnation, press moulding, winding, etc..
Metal, wood, plastics, ceramics, etc., can be joined with high-strength bonds without the application of contact pressure. Curing takes place virtually free of shrinkage.
Hardener HT 2:
Cycloaliphatic amine that is used at room temperature. As with all cold-curing epoxy resin systems, it is also possible to apply additional hot curing at 50 °C for ten hours to enhance the mechanical and thermal properties.
Please order Hardener HT 2 separately.
