Crestomer® Bio 1140PA

Chemical Family: Urethane Acrylates

Crestomer® Bio 1140PA is a two-part, pre-accelerated, highly thixotropic structural adhesive based on unsaturated urethane acrylate with more than 20% bio-derived content that is completely styrene-free. It is used in various structural composite applications and exhibits excellent adhesion to FRP laminates, core materials, wood, and certain metals. Due to its versatile adhesion properties, Crestomer® Bio 1140PA can also serve as a general-purpose adhesive. It can bond diesel tanks, contour joints in FRP components, repair damaged areas, and bond "green" FRP.
