RECOMMENDED FORMULATION USE

PEAM-1044 is recommended for use as a base resin. It has excellent adhesion with low stress due to its high Tg DCPD units. The oligomer has good solubility in both aliphatic and aromatic resins. Exceptionally low warpage can be achieved with the addition of polybutadiene type resins.
