Resin To Hardner Mixture - Diamond DA20-C1 Maintenance Manual

Standard Practices - Structures
C. Procedure
(1) Weigh the cut cloths and determine by ratio the resulting mixed resin weight. The ratio for
glass fiber cloth to resin is: 100:70 and the ratio for carbon fiber cloth to resin is: 100:85.
(2) Dispense only as much resin and hardener as you are able to use within the "working life" of
the resin, at the measured ambient temperature in accordance with the mixture table on
paragraph 9. A very common average mass is 100 g resin per pot. The dispensing error for
the mixing ratio should not be more than 0.5 percent.
(3) Mix the components thoroughly for several minutes. Always scrape the stirring utensil
surfaces as well as the sides of the mixing container, to ensure mixing of all components.
(4) Always thoroughly mix the resin system components before adding fillers or other additives.
(5) Note that small batches tend to have greater dispensing and mixing errors than larger
batches. Therefore, even more care is required when mixing small batches.
(6) Avoid dispensing components into different containers prior to mixing. Best accuracy is
obtained by weighing the resin and the hardener into a single mixing pot. Dispensing by
weight tends to be more precise than dispensing by volume.
(7) Large batches of mixed resin should be poured into flat containers, so that the surface area to
volume ratio is increased. This will reduce the risk of an exothermic reaction.
(8) Note that the resin on the rollers, brushes and other tools will also "cure". For this reason,
clean the tools regularly when lamination is continuing for an extended period of time. Use
only new brushes.
(9) Do not permit resin to become contaminated with foreign substances, other than the specified
additives. Solvents and thinners used to clean the equipment should be dried off before
commencing work with the tools.

Curing of resin / hardener mix happens by an exothermic reaction. Therefore,
leftover resin may overheat and is a potential fire hazard. it may cause injury to
personnel.
