In terms of processability of the resin this marks an important stage: before gelation the system is relatively mobile, after it the mobility is very limited, the micro-structure of the resin and the composite material is fixed and severe diffusion limitations to further cure are created. What is the difference between c-chart and u-chart? Grade 102 USPL offers ultra-low lead (the lowest lead attainable), with the highest m2/g surface area (SA) available with high quality French Process material.
