EasyFlo 60 -White Polyurethane Resin-

EasyFlo 60 is an ultra-low viscosity polyurethane resin (60 cP) that produces bright white casting parts, virtually bubble-free without the need for a vacuum chamber. With a simple 1:1 mix by volume and a pot life of just 2.5 minutes, it is the most straightforward option for part reproduction, rapid prototyping and special effects props.

Technical specifications

* Cure time varies depending on cast mass and ambient temperature.

What it is used for

Thanks to its exceptional fluidity and fast cure cycle, EasyFlo 60 fits any process where faithful detail reproduction, high productivity and parts ready to finish or machine in a short time are required:

• Reproduction of small and medium-sized sculptures and artistic pieces
• Rapid prototyping of industrial or design parts
• Props and set dressing for special effects (film, television, theatre)
• Parts for rotational moulds
• Series production of decorative or signage elements
• Architectural or engineering scale models
• Reproduction of parts that will subsequently be painted or lacquered

How to use it

1. Prepare the mould: make sure the mould is clean and dry. Apply a release agent if the mould is not silicone or if the surface is porous, to ensure clean demoulding without damaging the part.
2. Bring components to temperature: keep part A and part B at room temperature (20-25 ºC). In cold environments, curing slows down and more bubbles may appear.
3. Weigh or measure the components: mix in a ratio of 100A:100B by volume or 100A:90B by weight. For greater accuracy, use a precision scale.
4. Mix carefully: stir for approximately 30-40 seconds, scraping the sides and bottom of the container. Avoid whipping to prevent introducing unnecessary air.
5. Cast immediately: you have 2.5 minutes of pot life. Pour the mixture in a thin stream from a certain height to break any bubbles as it falls.
6. Allow to cure: the material reaches demoulding rigidity in 15-30 minutes depending on mass and temperature. Do not force demoulding prematurely.
7. Demould and finish: the part can already be sanded, painted, lacquered or machined. To colour in bulk, add PolyColor pigments to part A before mixing with part B.

Tips for use

Bubble control without a vacuum chamber

EasyFlo 60's viscosity of 60 cP is so low that bubbles rise and burst on their own in most cases. To maximise this effect, pour the mixture in a thin, continuous stream from around 20-30 cm in height. If the mould has complex geometries, tilt it slightly during the first few minutes so that air can escape. Only in the case of highly technical parts with deep undercuts is it worth using a vacuum chamber.

Pigmentation and finishes

EasyFlo 60 works perfectly with PolyColor pigments. Add the pigment to part A, mix thoroughly until the colour is uniform, then incorporate part B. Do not exceed 3-5% pigment by total weight to avoid altering the mechanical properties. Cured parts can be painted with water-based or solvent-based paints and can be machined with a milling machine, lathe or sander without any problem.

Storage and shelf life

Keep containers tightly closed and away from moisture. Part B is particularly sensitive to ambient humidity: if the container has been open for some time, check that it has not thickened or formed lumps before use. Store between 18 and 25 ºC. Once opened, use within a reasonable period to ensure correct reactivity of the components.
