Pre-filled means the resin or hardener has been filled with silica sands before delivery, providing convenience and consistency in your manufacturing process.
Generally, pre-filled resin is more cost-effective. However, if you can source qualified silica sands locally, pure resin may offer better overall value considering shipping costs and material availability.
We've already incorporated flexibilizers and accelerators into our resin and hardener formulations during manufacturing. This ensures optimal performance and simplifies your production process without requiring additional additives.
