Product catalog summary
Product Overview: The ALUMINIUM 250TV is a fine aluminium powder with an average particle size of 60 µm, used primarily as a filler to enhance the properties of casting resins and improve adhesion in laminates.
Applications: It is used to increase filler content in RESOLTECH epoxy gelcoats and aluminium casting resins, transforming them into thick pastes and improving thermal conductivity. It also enhances mechanical adhesion between gelcoats and reinforcement layers.
Application Procedure: The powder should be spread over freshly applied gelcoat. Once the gelcoat hardens, excess powder is removed, leaving a fine layer that ensures mechanical adhesion. Timing for application is crucial and should be tested in small samples.
Physical Characteristics: The powder has a granulometry of <45 µm (60-85%), >45 µm (15-60%), and >75 µm (<5%). Chemical composition includes Al: 99.7% min, Fe: 0.2% max, Si: 0.12% max, Cu: 0.01% max. Apparent density is 0.93-1.0 g/cm³, and bulk density is 2.7 g/cm³.
Packaging: Available in 5 kg, 25 kg, and 50 kg packages.
Health & Safety: Basic safety measures include wearing masks to avoid dust inhalation. In case of eye contact, rinse with water and seek medical advice.
Transport Information: Classified as non-dangerous according to UN, IMO, ADR/RID, and IATA/OACI regulations.
Coverage: For flat mould applications, plan for 350 gr/m², with approximately 180 gr/m² remaining bonded after excess removal.

RESOLTECH ALUMINIUMMINUM FINE ALUMINIUMMINUM POWDER/FILLER Ideal to create a mechanical cling between gelcoat and following reinforcement layers or castings. Increasing of filler content in all RESOLTECH epoxy Gelcoats & ALUMINIUMminium casting resins The ALUMINIUM 250TV is an ALUMINIUMminium powder with average particle size of 60 µm. . The ALUMINIUM 250TV maybe used as filler for the 2060 ALUMINIUM 25 or the 1450T ALUMINIUM in order to increase the filler content these casting resins and transform them into thick pastes & improve the thermal conductivity of these casting resins. The ALUMINIUM250TV may also be used to improve adhesion of laminates onto epoxy gelcoats, by providing a mechanical bond rather than chemical bonding.

APPLICATION Powder spread generously the ALUMINIUM 250 TV powder all over the freshly applied gelcoat in order to completely cover it. Once the gelcoat hardened, the excess of ALUMINIUM 250 TV must be removed with a brush or a vacuum cleaner, leaving on the back of the gelcoat a fine layer of aluminium with the texture of a 400 grit sanding paper. The filler embedded on the gelcoat will ensure an excellent mechanical adhesion with the reinforcement to be laminated or infused on it. Tip: The right moment to spread the ALUMINIUM 250TV on the gelcoat depends on the reactivity of the gelcoat and...

Resoltech ALUMINIUM 250TV COVERAGE When applying the Aluminum powder onto the gelcoat on a relatively flat mould (largest posible consumption), an average of 350 gr/m2 should be planned. Once the gelcoat has hardened and the excess of Aluminium 250 TV removed, approximately 180gr/m2 will stay bonded onto the gelcoat. LABELLING / TRANSPORT Non dangerous according to UN,IMO, ADR/RID and IATA/OACI regulations. HEALTH & SAFETY It is advised to follow basic rules such as , wear masks when producing dust. Please read our standard health and safety sheet for more information. In case of eye contamination,...
