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 mixing with hardener!

Tip 4: Regarding temp ramp-ups, the smoother, the better. This way, we allow the materials to deform at its given time. 

Here some tricks and tips

  1. Press for 3 minutes (Room temperature)
  2. Start ramping up (10C every 5 minutes i.e.) the temperature to 85C for 15 minutes, let it cool (6 hours at least or overnight) otherwhise it can bend and deform if its demolded at high temperature.
  3. Switch off the pressure 

+Fast ramps produce different deformation speeds which are converted into internal tensions between the different materials.

Description

Polar bear is a heated compression bio based epoxy.

  • Applications: Polar Bear Recyclable Epoxy System is specifically formulated for compression molding applications, such as for skis and snowboard manufacturing. Heat assisted curing.
  • Mix Ratio: 100:46 by weight

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.
