Overview
Synolite 8388-P-1S has been especially developed for hand lay-up and spray-up applications to produce high performance constructional laminates. It combines good mechanical properties with optimal processability. As one of the recommended international brand products in our resin range, this resin is supplied with supply chain resource support for fabricators sourcing a low styrene emission resin for constructional laminates.
Key Benefits of Synolite 8388-P-1S
- Low shrinkage and good surface
- Outstanding wetting and operation performance
- Low styrene emission
- Good curing with thin lamination
Applications
Synolite 8388-P-1S shows very good fiber wetting and impregnation properties, supporting building and construction and automotive and transportation constructional laminate applications. Thick laminates can be made in one go due to the low exothermic heat development, good through cure, and relatively low shrinkage. It can be used with powder and emulsion bound mats.
Why Low Exothermic Heat and Low Styrene Emission Matter
When building up thick constructional laminates in a single pass, excessive exothermic heat during cure can cause print-through, warping, or even resin degradation before the laminate fully sets. A resin engineered for low exothermic heat development and good through cure gives fabricators more flexibility to build thickness in one go rather than requiring multiple thin passes with cooling time in between, which can help simplify scheduling on a constructional laminate production line.
An optimized low styrene emission (LSE) system also supports a better working environment during hand lay-up and spray-up application, which is particularly relevant for fabricators operating under increasingly strict workplace styrene exposure limits. Combined with outstanding wetting and operation performance, this makes Synolite 8388-P-1S practical for shops that need both a comfortable working environment and reliable laminate quality. Fabricators should always confirm current styrene emission data, geltime, and viscosity against the latest technical data sheet for their specific process.
What to Consider When Sourcing Synolite 8388-P-1S
When sourcing a low styrene emission resin for constructional laminates, fabricators typically evaluate exothermic heat development, cure schedule for thick sections, compatibility with powder and emulsion bound mats, and styrene emission performance against workplace exposure requirements. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new resin for a constructional laminate line.
Because this resin includes a color change system for the benefit of spray-up applications, fabricators using spray-up as their primary process should confirm current color change behavior and timing against the latest technical data sheet, since this feature is specifically intended to support visual confirmation of coverage during spray-up rather than hand lay-up.
General Handling and Storage Guidance
As with most unsaturated polyester resins, this product should be kept in tightly sealed original containers, stored in a cool location away from direct sunlight and heat sources, and used within the manufacturer’s recommended shelf life. Because low styrene emission systems can be formulated differently from standard resins, fabricators should avoid storing containers near heat sources or in direct sun for extended periods.
Shelf life and specific storage temperature ranges vary by batch and packaging format, so fabricators should always confirm current shelf life, recommended storage temperature, and any handling precautions against the latest technical data sheet and SDS for the specific batch of Synolite 8388-P-1S they are working with.
How Hand Lay-Up and Spray-Up Requirements Differ
Hand lay-up applications typically prioritize good fiber wetting and impregnation, since operators need the resin to fully saturate reinforcement by hand within a workable geltime. Spray-up applications place additional emphasis on features like the color change system, which helps operators visually confirm even coverage across a mold surface during application, a benefit that is less relevant to manual hand lay-up work.
Because this resin is positioned for both hand lay-up and spray-up processes, fabricators switching between these methods, or qualifying it for a new process, should confirm current geltime and viscosity recommendations for their specific method rather than assuming identical performance across both.
