Structural epoxy resin system for wood Adjustable pot life from 15mn to 9 hours Excellent wood wettability. High gloss aspect in all conditions Little sensitivity to humidity during application Available in thixotropic version (1020T) RESOLTECH 1020 is a advanced epoxy laminating system for wood-epoxy constructions. It may be used for: all woods laminations, coating, scarfing, strip planking, as well as bonding in form of fillet joints applications when filled with wood flour and silica. Thanks to its low viscosity and a wide range of hardeners (15 min to 10hours), it allows applications in both traditional wet layup, vacuum bagging or under press. A thixotropic version , the 1020T is available for vertical or overhanging applications prone to dripping. The mixing ration for all hardeners of this system is 100:30 by weight or 3:1 in volume. All hardeners are compatible and can be mixed to obtain intermediate reactivities. Once cured, manufactured pieces can be released from the moulds without post curing. 90% of thermomechanical properties of the resin will be obtained after 7 days at room temperature. The highest quality of the RESOLTECH 1020 system is its exceptional wettability making hand lamination easier to the workers while guaranteeing a safer work place due to the low toxicity of this system. The 1020 resin system is also widely used in civil engineering applications on glass and carbon laminates where it´s little sensitivity to humidity during it´s application and good curing properties at ambient temperature are appreciated.

MIXING RATIO The mixing ratio must be respected neither excess nor default. The mixture should be homogeneous and intimate with the use. APPLICATION It is recommended to use products to a temperature close to 18-25 ° C in order to facilitate the mixing and the reinforcements impregnating. Lower temperatures will increases the viscosity of the mixture and the gel time, but the resin will not cristalize at low temperatures. On the contrary, a higher temperature will reduce the viscosity of the mixture and well as the pot life PHYSICAL CARACTERISTICS Visual aspect 1020 : Opalescent neutral...

GEL TIME Gel times are measured according to ISO 2535 RESIN / HARDENER SYSTEM RETICULATION & POST-CURING 90% of the thermo-mechanical properties are obtained after 7 days at room temperature (25°C). To obtain a material at its highest thermomechanical properties with aTG of up to 60°C, it is necessary to postcure the laminate. It is important not to cure the system at a temperature above 50 ° C. Higher temperatures crosslinkings during initial cure may create tensions in the laminate. Higher post-curing temperarures than 50 ºC are suitable once the initial crosslinkings are established....

IECHANICAL CARACTERISTICJ Values on non reinforced resin after 7 days at 23°C * Composite manufacturing Values for the test were obtained on laminates of 16 layers of glass twill 2-2 of 285 g/m2. Average rate of impregnation of the laminate: 74% +1-2% of fiber by weight. The laminate was manufactured under press. RESOLTECH RESOLVING YOUR ENGINERING CHALLENGES
