Product compatibility

• Previous coat: None or according to Hempel’s specification. Recommended products are: Hempel's Galvosil 15700, Hempel's Galvosil 15680, Hempel's Galvosil Fibre 15750
• Subsequent coat: None or according to Hempel’s specification. Recommended products are: Hempel's Silicone Topcoat 56900, Hempel's Silicone Acrylic 56940, Hempel's Silicone Aluminium 56910

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C

Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval. For best performance, avoid excessive film thickness. Overthickness should be closely controlled and never locally exceed 225 micron DFT. On irregular surfaces it is recommended to employ special care in avoiding over application
