Pre-filled means the resin or hardener has been filled with silica sands before delivery to customers.
Generally yes, but consider final costs. If qualified silica sands are available locally, pure resin may be more cost-effective due to lower shipping costs.
We've already added flexibilizer and accelerator into the resin/hardener before delivery, making our materials easy to use without additional additives.
