305 (CPM)/CPL heated compression Bio based epoxy (Slow)

45.00150.00 "incl. VAT"

Compression molding elevated temperature resin. Also called 305.

Soon we will replace this product with a very similar product called Polar Bear from our supplier.

Pot life is 50min. Cure time is 20min at 80 degrees.

mix ratio is 100:38g (resin:hardener)

best to be used at 60 degree C or above for pneumatic press.

Low smell, low toxicity! Great to work with and more environmental!


Make sure you use a digital scale. Mix by weight.

Make sure you use gloves.

Tip 1: Mix a pot of 200-300mL of epoxy at the time. Dont mix much more then this. Stir well for 2min with your hand, scrape the edges. The mix can become a bit hot, this is normal. Let it sit for 1-2 minutes for air to escape!

Tip 2: make sure you are protected with gloves as skin contact it the worst exposure.

Tip 3: If any crystals are present in the Resin, please make a warm water bath (about 50C or above should do, in production the resin is heated to 100 degrees so no worries) and place the Resin container in the warm water and stir til crystals are gone. This is normal for some Resins. Let it cool down before use! Do this before mixing!

We are transitioning to a new brand of resin (due to the changes and huge price increase). Our priority is quality and bio based, still working with the same company and supplier! Entropy will not be available in the future.

Application Tips:

  • For best results, measure the two components by weight within 5% of the recommended mix ratio.
  • Always mix product for at least two minutes, scraping the container to ensure complete mixing.
  • Use products in a controlled environment. Avoid high humidity and cold temperatures.
  • Amine blush, a by-product of the curing process, appears as a wax-like film cured epoxy and is more noticeable in cool, moist conditions. It can clog sandpaper and inhibit subsequent bonding. Blush is water-soluble and easily removed with clean water (not solvent) and an abrasive pad.
  • For good adhesion, epoxy bonding surfaces should be clean, dry and sanded.
  • If unfamiliar with the product, create smaller test samples before starting a larger scale project.
