207 Special Clear Hardener (Reformulated)

105/207 Epoxy is used for coating and fibreglass cloth application where exceptionally clear moisture-resistant, natural wood finish is desired. 105/207 Epoxy is more blush resistant and less likely to turn cloudy in humid conditions. Thin film applications roll out and tip off smoothly, requiring less sanding in preparation for finish coatings. Three coats or more can be applied in one day without additional surface preparation. Fewer coats are required to fill fibreglass weave and in most cases the final coating can be sanded the following day.

105/207 Epoxy forms a high-strength, moisture-resistant solid with excellent bonding and barrier coating properties as well as being a structural adhesive for gluing and laminating. It has excellent compatibility with paints and varnishes. An ultraviolet inhibitor in 207 helps provide a beautiful, long lasting finish when used with a high quality UV-filtering varnish. It is formulated without volatile solvents resulting in a very low VOC content. It has a relatively high flash point, no strong solvent odour and does not shrink after curing.

Pot life at 25°C:25 to 30 minutes
Cure to solid state at 21°C:10 to 15 hours
Cure to maximum strength at 21°C:1 to 4 days
Minimum recommended temperature:16°C
