Havel Composites CZ sro Epoxy resin LH 260

Havel Composites CZ sro Epoxy resin LH 260 is characterized by low viscosity. When curing amines or polyamines offer high quality application properties such as high mechanical properties, good chemical resistance, excellent temperature properties, etc. It is a low viscosity resin based on bisphenol A. Viscosity: 700-900 mPas / 25 ° C. 3Crystallization does not occur at normal storage temperatures. The advantage of the mixture resin and the recommended hardener is its clarity.

Features & Benefits

Special Properties

The resin is clear even at a temperature of 0 - 10 ° C, there is no turbidity as in QSome epoxy resins. The hardener resin creates a low viscosity before lamination a system that allows good wetting and saturation of the fabric while displacing bubbles from the laminated system, thus improving the mechanical properties. Workability time / so-called pot life / by pĜibliåQČ 15 min. within about 5 hours depending on the used tuåidla Temperature resistance of the product without significant changes in their parameters: > + 50-100 ° C Processing: At temperatures between 10 ° C and 50 ° C, all common processing methods.

Applications & Uses

Applications

Shipbuilding, sports equipment, aircraft models, molds and tools, adhesives, castings

Laminating Resin Systems for Curing at Room Temperature

Different combinations of laminators can be used for curing at room temperature from 10 - 30 ° C. resins and hardeners. These systems have been modified in such a way that at room temperature completely harden. Heat resistance 40 - 60 ° C can be achieved by curing at room temperature / so-called. rule inches: curing temperature + 30 ° C = maximum heat resistance. Thermal resistance of these systems can be increased to approximately 90 ° C by gradual thermal tempering at temperatures 50 -70 ° C

Uses

The laminating resin and hardener system has different workability times (depending on used), for production using glass, carbon and Kevlar fibers and is characterized by high static and dynamic properties. Can also be colored pigment.
