Description
105 EPOXY RESIN
105 Epoxy Resin is a clear and low-viscosity liquid epoxy resin, that offers excellent performance. It is specially formulated to work with any of the available WEST SYSTEM hardeners. This versatile resin can be cured over a wide temperature range, resulting in a strong bond with exceptional moisture resistance. When mixed in the proper ratio with a WEST SYSTEM hardener, 105 Epoxy Resin becomes a reliable adhesive for various applications. It is formulated without volatile solvents and does not shrink after curing. Moreover, it has a relatively high flash point and no strong solvent odour. This makes it safer to work with than either polyester or vinylester resins.
A WIDE RANGE OF APPLICATIONS
WEST SYSTEM 105 Epoxy Resin is an excellent adhesive with many applications. Used in conjunction with WEST SYSTEM fillers, it is used to bridge gaps and fill voids which, when cured, can be sanded and shaped.
When used with a roller, WEST SYSTEM 105 Epoxy Resin exhibits excellent thin-film characteristics which enable it to flow out and self-level without the adverse effects of ‘fish-eyeing’. This is thanks in large part to its viscosity of approximately 1000 centipoise (cp) at 22°C. When used with WEST SYSTEM 207 Special Clear Hardener™, on the other hand, it cures with excellent clarity making it suitable for achieving a natural wood grain finish when coating with varnish.
105 Epoxy Resin is designed to wet out and bond to:
Wood fibre
Fibreglass
Reinforcing fabrics
Composite materials
Variety of metals
STORAGE AND SHELF LIFE
With proper storage, WEST SYSTEM 105 Epoxy Resin and hardeners should remain usable for many years, especially if the containers are kept closed in order to prevent contamination. Over time, the resin will thicken slightly which, in turn, will require extra care when mixing. Both resin and hardeners should be stored at room temperature. Indeed, if the resin freezes and thaws out many times it can cause crystallisation. If this happens, however, it is a simple matter to dissolve the crystals by warming the resin to 50°C and stirring for a while.
