1. A bio-based binder system useful for the formation of fiberglass insulation, the system comprising:
- A) an aqueous curable binder composition comprising;
(i) at least one carbohydrate;
(ii) at least one crosslinking agent; and
B) a dedust composition comprising a blend of;
(i) a blown, stripped plant-based oil having a viscosity of at least 200 cSt at 40°
C., a flash point of at least 293°
C., and having an acid value less than 5.0 mg KOH/gram; and
(ii) from about 0.5 percent by weight to about 11 percent by weight, relative to the amount of the blown, stripped plant-based oil, of a refined, bleached, and deodorized plant based oil having greater than 0.0 percent by weight and less than 2 percent by weight 18;
3 fatty acid content,wherein the bio-based binder system comprises at least one emulsifying component and wherein the bio-based binder system comprises 10 parts per million sulfur or less based on the weight of components A) and B), excluding water.

Abstract
An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.
