Surface green strength

Polyester diols are often combined with polyether diols to provide green strength through crystallization or elevated r . Most prevalent and least expensive is hexamethylene diol adipate (HDA) with a Tm of about 60°C. A variety of polyesters are available with various levels of crystallinity — from wax-like to amorphous — and crystallization rate, and with values ranging well below 0°C to above room temperature. Polybutadiene diols are the most expensive and most hydrophobic. They provide low surface tension and thus good wet out of non-polar surfaces. 

Foundry core oil. CNSL resins are known to impart good scratch hardness to sand core after they are baked [133,134,137,167]. It also provided resistance to moisture and weathering and good green strength, and surface finish to molded articles.
