For two years in a row, TSE won the JEC Americas Innovation Award, and we couldn't be more proud of our Composites Team! 

The Biobased, Drop-In Solution for Styrene Polyester. TSE-EcoSpray® Bio 550C and TSE-EcoSpray® Bio 530C are USDA Certified Biobased Products under the USDA's BioPreferred® Program.  They are polyurethane spray layup resins for reinforcing consumer and industrial fiberglass composite structures, such as baths, hot tub spas, boats, motor vehicle parts, construction and many others. They can be used with fiberglass chop. These new resins are a drop-in solution that can replace styrene polyester in many applications.  They're 1:1 by volume, so application is quick and easy.

TSE-EcoSpray Bio resin is VOC and BPA-Free, and that's getting to be more important every day. Current regulations in the U.S. generally allow 20 PPM for styrene emissions. Since TSE-EcoSpray Bio reinforcing resin is totally free of solvents, VOC's and BPA, you can manufacture your hot tub spas and tubs without those nasty styrene odors, and without the need for Title V permits!

Styrene "Reasonably Anticipated to be a Human Carcinogen."  On July 28, 2014, the National Research Council on the National Academies (NRC) published a Report titled "Review of the Styrene Assessment in the National Toxicology Program 12th Report on Carcinogens."  The Report, prepared by a panel of scientists, states "compelling evidence exists to support a listing of styrene as, at a minimum, reasonably anticipated to be a human carcinogen."   

The time to switch to safe, environmentally preferable alternatives is NOW!

Non-Foaming in Ambient Humidity.  TSE-EcoSpray Bio can be applied in the ordinary FRP shop environment without foaming!  No climate control needed!  

A USDA Certified Biobased Product.  Our urethane reinforcing resin is a USDA Certified Biobased Product under the USDA's BioPreferred® Program.  This serves as independent verification of the percentage of biobased materials in our products.   

Environmentally Preferable. Same Great Properties. No Additional Cost.  TSE-EcoSpray Bio gives you the "environmentally friendly" solution without sacrificing flexibility, adhesion, tensile strength or Tg, with hugely superior impact resistance compared to styrene ester resins.  All of this at no additional cost for an environmentally preferable product!  

Renewable & Sustainable.  TSE-EcoSpray Biobased polyurethane reinforcing resin is made from renewable natural oils, forming a key component of sustainable design. TSE-EcoSpray Bio is Sage Green in color as a reminder that you can help the environment while marketing your environmentally friendly hot tub spas and tubs to "Green-minded"consumers, driving more "Green" into your pocket!
