Synolite 8-P- Chemical/physical nature Synolite 8-P- is a low viscous, pre-accelerated, promoted, thixotropic, medium reactive unsaturated polyester resin based on orthophthalic acid. An LSE additive and a colour change system have been incorporated. Synolite 8-P- does not contain monomeric amines. Major applications Synolite 8-P- has been especially developed for hand lay-up and spray-up applications to produce all kind of constructional laminates. Principal properties Synolite 8-P- combines good mechanical properties with optimal processability. This resin shows very good fibre wetting and impregnation properties and can be used in combination with different types of glass mats (powder and emulsion bounded), woven roving and fabrics. Thick laminates can be made mostly in one go due to the low exothermic heat development combined with fast through cure, even in very thin laminates. An LSE system is incorporated to get excellent Low Styrene Emission. Extra application properties can be found on pages -7. For short gel times Synolite 8-P- can be used.

Synolite 8-P- Processing Synolite 8-P- contains barrier forming agents to reduce emission of styrene. These agents may reduce the bonding strength of overlaminates. Good strength can be obtained with overlaminating of the base laminate after delayed lay-up if the surface is not too resin rich. In other cases the surface might need sanding. Guidelines before use The resin should be conditioned at C minimum before use to obtain a sufficient cure when MEKP is used as a curing system. Stir the resin before use. Storage guidelines The resin should be stored be stored in a dark and dry place at temperatures between C and C. The shelf life of styrene containing unsaturated polyesters will be significantly reduced when exposed to light. Store in dark and in % light tight containers only.
