Resin is vital material for kayak parts. The injection molding process and the drying temperature are crucial for kayak part production. Too high Process temperature could cause material decomposition, on the other hand, when process temperature is too low, the resin might not be able to melt which could cause screw damage. Almost all the resins absorb moisture quickly except non-hygroscopic resins(PP, PE), non-dried resins could cause watermarks or splays (streaks or bubbles). Thus, drying resin for enough time is necessary. BroadPlast kayak hardware manufacturer lists common resin process conditions (mold temperature) and resin drying conditions below for your reference.
