Urea-modified furfuryl alcohol resins
Cores made using resins of this group are mainly employed in casting operations where a certain thermal stability, coupled with good core collapse after pouroff is required. Such resins are thus excellent for use in production of aluminum cylinder heads (low condensate levels) and malleable iron castings that are prone to cracking. At elevated levels of furfuryl alcohol, such resins are naturally also suitable for use in gray iron casting.
