Resoltech 8050/8058 Epoxy Profiling & Fairing Filler

RESOLTECH 8050 / 8058 is a fast curing, lightweight, and easy sanding epoxy filler.

It is a premium choice for profiling & fairing above and below the waterline for professional applicators on steel, aluminum and composite materials.

The specially formulated lightweight epoxy filler will apply from very thin layers up to 30 mm in  one coat without the risk of sagging/slumping. This filler will result in a high strength and impact resistant watertightsurface

The formulation of the 8050 will help improve health and safety for the workers and follows the latest EU regulation (CE) n° 453/2010  and does not contain any CMR materials.

When sanded, the surface of this system is smooth enough to be directly overrated with 2 coats  of RESOLCOAT 3010T / 3014T high build epoxy primer and is compatible with all paints & primers. RESOLTECH 8050 / 8058 fast curing characteristics enable applications of 2 to 3 layers of a day with sanding between them, improving the productivity of the workers, It may be applied in covered facilities or outside as it offers little sensivity to climateconditions

Its excellent waterproof quality enables to guarantee long lasting barriers when used as Osmosis treatment. Easy to sand or mill with CNC, RESOLTECH 8050 / 8058 may be used as profiling filler on low density foams blocks for plugs manufacturing and tooling boards adhesive.

RESOLTECH 8050 is the product that offers long-term performance of superior quality.

Mixing ratio

The mixing ratio must be respected neither excess nor default. The mixture should be homogeneous and intimate with the use. It is recommended to use flat spatulas & trowels to hand mix the resin & hardener on a flat surface to avoid air incorporation during the mix.

Application

It is mandatory to respect the mixing ratio, all excess or default will result in a loss of thermo- mechanical properties.

< Substrate temperature should be minimum 10°C andmaximum  35°C.  Product  temperature should also be minimum 10°C and maximum 35°C. Ambient temperature should be minimum 10°C and maximum35°C.

< Surface preparation: on previously painted surfaces, clean thoroughly to degrease the surface and sand with 80-180 grade paper or remove all previous coatings if in poor condition and prime thesubstrate.

Steel Aluminum: Prime with RESOLCOAT 3010T / 3014T.

Wood: Prime stable constructions only, with RESOLCOAT 1010 / 1014.

GRP: For osmosis treatment, prime the sanded fibre with 1020T/102XS in order to waterproof the substrate and lightly sand/deglaze before application of filler.

BARE GRP/COMPOSITE: Remove surface wax/mould  release  agent  with  degreaser,  sand with 80-180 grade paper. If left for longer than 24 hours, two component epoxy primers and fillers will need sanding with 80-180 grade paper to ensure a good mechanicaladhesion.

As general rule: all substrates must be sanded, clean and dry.

< Mix the two components thoroughly to an even colour. Remove any dust  from  the surface. Apply firmly in a spreading action. When hardened, sand smooth with 80-180 grade wet or drypaper.

< Overcoating: RESOLTECH 8050 / 8058 may be over coated with itself or  with  RESOLCOAT 3010T / 3014T as soon as it is cured enough not to be lifted during the screeding process.

Coverage of application vs thickness

Coverage will depend on the thickness needed to profile. The following table indicates the coverage vs thickness.

Warning : On thick applications, with high temperatures it is recommended to test the desired thickness at application conditions & substrate temperature  to ensure that no exothermic reaction may occure.
