A key innovation initiative is the transition to partially bio-based epoxy resins. By replacing a portion of fossil-based raw materials with renewable feedstocks, these formulations can help reduce the use of fossil resources while maintaining the performance requirements of construction and industrial applications.*

Embracing bio-based solutions
Traditionally, the epoxy industry has relied on "fossil" epoxies, but Sika is making a conscious shift to bio-based alternatives.
The bio-based glycerin used for epichlorohydrin synthesis is a by-product of biodiesel production and primarily derives from waste oils, leftover cooking fats from large kitchens, rapeseed oil, and other vegetable oils. This shift not only reduces reliance on fossil resources but also paves the way for more sustainable manufacturing processes.
Sika successfully produced flooring coatings with epoxy resins containing 28% of bio-based carbon. This commitment to sustainable epoxy resins not only signifies a substantial reduction in Sika’s reliance on fossil resources but also underscores Sika's unwavering commitment to environmental responsibility.
