Isocyanate Resins - CASE Study

The CASE (Coating, Adhesives, Sealants, and Elastomers) industries are experiencing an evolution in new product formulations. The need for environmentally friendly products has never been higher. Consumers and businesses are demanding sustainable products and a reduction of environmental impact from the CASE industries.

CASE product formulators are challenged today to transition products from fossil fuel-based raw materials to renewable alternatives. Bio-based solvents can play a crucial role in making this shift possible. Many solvent-based traditional formulations cannot be replaced with alternative technologies due to poor product performance or application constraints. Bio-based solvents can aid the product formulator achieve the goal of providing a sustainable formulation with minimum impact on performance.

Key criteria for replacing petroleum-based solvents are compatibility with commonly used resins in current formulations. The selection of the proper bio-based solvent (or blend) can offer a sustainable solution and potentially offer a VOC reduction in specific formulations. An additional benefit of a bio-based solvent formulation can be a reduction in the overall carbon footprint for CASE companies.

Vertec BioSolvents, Inc. is an innovative manufacturer of sustainable, safe, bio-based green solvents and solvent blends derived from corn, soybeans, citrus and other renewable feedstocks. Our latest R&D efforts have demonstrated many commonly used solvent-based resins formulations can benefit from inclusion of bio-based green solvents.

Isocyanate Resins

Isocyanate resins are used in two-component and one-component urethane coatings and adhesive formulations. Aliphatic urethane coatings offer excellent weather resistance and are the coating type most used for aircraft and automotive finishes. Petroleum-based solvents have traditionally been used to dissolve / solvate isocyanate resins. The use of biosolvents to replace them can lead to a greater sustainable formula and potentially lower the VOC of the product.

Below are examples of Vertec BioSolvents products compatibility and viscosity behavior with a popular aliphatic isocyanate resin.
