1.The moldings need to condition for 1-2 days after processing to develop their full strength. During the conditioning the starch component reabsorbs its moisture content making it more ductile. 2. BIOGRADE B-M resins can be blended with natural fibres such as flax, hemp, sisal and coconut hair (coir) to add reinforcement and to assist with water-wicking into thick section mouldings. 3. Wet resin should be dried before processing to limit degradation induced by water (hydrolysis)
