Crystic® Polyester Resin 195
Crystic® Polyester Resin 195 is a light-stabilized polyester resin containing styrene and methyl methacrylate. When combined with powder-bonded "E" glass, it is recommended for the production of maximum-clarity GRP sheeting with up to 80% light transmission. This product has a 25-minute gel time.

- Pot Life
The amount of Accelerator E can be approximately determined from the table below.. The resin and the workshop should be at, or above, 15ºC before curing is carried out.
- Additives
Crystic195 may be colored by the addition of small quantities of light stable translucent tints. Tests should be made by the user, to ensure even color distribution.

- Formulation Guideline
Crystic195 should be allowed to attain workshop temperature (18ºC - 20ºC) before use. It requires the addition of a catalyst and an accelerator to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50) which should be added at 2% into the resin. The catalyst must be thoroughly dispersed in the resin, and this mix will remain usable for approximately 24 hours at workshop temperature (18ºC - 20ºC). Shortly before use, the correct amount of Accelerator E should be stirred into the catalyzed resin. N.B Catalyst and accelerator must not be mixed together, directly, as they can react with explosive violence.
