Presto 2K epoxy resin 1000g

Presto Epoxy Resin - 2K

DESCRIPTION:
Presto Epoxy Resin is a 2-component, solvent-free, low viscosity, transparent repair, coating, laminating and potting resin.

AREAS OF APPLICATION
- For repairing, bonding and coating of porous and smooth surfaces
- As impregnating resin for fiber-reinforced coatings and molded parts
- As a potting compound for circuits and other cavities
- For the production of waterproof coatings, e.g. liquid-impermeable coatings for gutters, pipes and troughs
- For the production of particularly strong and lightweight GRP moldings: Together with a fiber reinforcement, suitable for linings and hoods in vehicle, apparatus and model construction.
- All work with wood
- Coating of concrete floors
- Repairs to boats, motor vehicles and other molded parts.

QUALITY AND PROPERTIES:
- The resin cures tack-free on the surface facing the air. - High strength, very high adhesion
- Very water resistant, low water absorption
- Low shrinkage during curing
- Solvent free, therefore low odor
- Resistant to weak acids, weak alkalis; inorganic salt solutions, petrol & petroleum, greases and oils
- Processing even at relatively low temperatures (min. 10°C)

TECHNICAL DATA:
- Base: epoxy resin
- Color: A-component clear; B-component yellowish transparent
- Odor: A-component slightly aromatic, B-component amine-like
- Pot life/processing time at 20°C: approx. 30 min. / At lower temperatures (minimum 10°C) pot life and curing time are extended. For larger batches, the processing time is shortened due to higher heat generation.
- Working temperature: from 12°C
- Consumption per application: for coatings in pure form approx. 250 g/m²; suitable for casting in layers up to 3 cm.
- Drying (at 20°C, 50% relative humidity): Sandable after: approx. 12 hours. / Final surface hardness is reached after approx. 3 - 5 days.
- Increased chemical resistance and strength is achieved by subsequent annealing at 50°C for 24 hours.
- Flash point: A-component 135°C, B-component >100°C
- Density at 20°C: A component 1.1 g/cm³, B component 1.04 g/cm³
- Viscosity: A-component approx. 1000 mPa.s; B-component approx. 700 mPa.s; mixed viscosity: approx. 950 mPa.s
- Specific gravity: A-component 1.15 g/cm³; B-component 1.0 g/cm³
- Temperature resistance of the cured material: 70°C
- Compressive strength: 70 N/mm²
- Tensile strength: 19 N/mm²
- Flexural strength: 57 N/mm²
- Shore D hardness: approx. 80
- Hardener addition: A-component (base) : B-component (hardener) = 100 : 60 parts by weight or 100:70 parts by volume
- Shelf life/storage: 24 months when stored properly (=10°-25°C, relative humidity of max. 60%) in closed original container. Hardener loses slightly in effectiveness with increasing storage time; therefore minimal increase of drying time possible. Protect from direct sunlight, frost and moisture.
