Whenever it is required to add a definite material thickness to any flat or contoured surface, sheet wax is commonly used.
For plastic fabrications with epoxy or polyester resins, Thermo Stable Sheet Wax can be used with every assurance that its dimensional stability will not be disturbed by the exothermic reaction during the curing process of the resin.
Sheet wax is an accepted essential material used for adding component thickness to cold press and resin injection moulds. The specially formulated adhesive will hold the sheet wax to its applied surface throughout the temperature resistance range of up to 266°F, this ability to continue to adhere during the curing period is important in maintaining accurate component thickness.
In cold weather it may be necessary to temper the sheet by artificial heat until it can be applied more readily.
Firstly coat with Shellac varnish and also a P.V.A. release agent for perfect release when casting plaster or G.R.P. against a sheet wax surface. Sheet wax is packed in cartons, each sheet is 24" x 12" (610mm x 305mm) and the adhesive coating is protected by easily removed backing paper. In 29 thicknesses from 0.010" to 0.375". (0.25mm to 9.5mm).
