Preparation of moulds.

Before casting, make sure that the details or moulds are free from traces of moisture (the maximum moisture content on the surface should not exceed 4%). Before applying
E- 4080, the prepared object should be coated with a suitable liquid mould release agent such as E 499 or an equivalent mould release agent to avoid sticking.

Mixing.

Mix component E -4080 B carefully before use. Then mix both components until smooth by using a slow mixer. Vacuuming improves the quality of work.

Component A and Component B E -4080 should be mixed with a low speed mechanical mixer according to the mixing ratio indicated on this data sheet for approximately 3 minutes when used manually. Two components (component A and component B) should be mixed at temperatures above 18 °C. Component B can be heated up to 40 °C to lower the viscosity, but this implies shorter application time.

CAUTION: mix the ingredients very carefully, especially on the sides and bottom of the bucket, until the mixture is completely homogeneous.

Application.

Brush E -4080 onto mould or prototype to avoid formation of air pockets. Pour the
E-4080 resin into the mould after 3-5 minutes.

TIP: Remove air bubbles with a suitable dryer or vacuum chamber.
