    Why A Kit?

    Biomaterials are not readily available to everyone today. That needs to change. We think amazing things will start to happen when renewable materials are more accessible and easy to use. And, we’ll all leave more fossil fuels in the ground.

    What are polyurethanes?

    Polyurethanes are a class of polymeric materials generated by reacting two types of chemical subunits,  isocyanates (molecules with multiple reactive isocyanate groups) and alcohols having multiple reactive hydroxyl groups (called diols, triols, and polyols). 

    In the universe, there are many types of isocyanates and polyols. Different formulations can be achieved by combining different subunits and by varying the amount of minor formulation ingredients.

    As a material class, polyurethanes are found everywhere. From the foam in your couch, the coatings on your car seats, the adhesives in your shoes, the wheels on your roller board, the bushings enabling the motion of millions of machines, as well as in tens of thousands of other products, polyurethanes a vital material for our modern functioning world. 

    What part of these formulations are biobased?

    The Pollinator Series formulations are made with Checkerspot's Algal Polyol 001, a USDA Certified Biobased Product. Each item made solely from the resin system will be ≥​56% biobased (ASTM D6866).

    How do I buy larger quantities or materials with different properties?

    We can custom formulate to achieve a range of properties. We want to talk with you about your project, part, product, and process. Please contact us to discuss.
