Fillers & thickeners

Fumed silica (thixotropic)

  • Prevents sagging and "runs" on vertical surfaces
  • Ideal for adhesive pastes and spatula systems
  • Mix in at low speed and dust mask

Fillite 355 (Lightweight)

  • Reduces specific weight, easy to sand
  • Perfect for filling and leveling pastes
  • Bonds in epoxy/PU; dosage per TDS

Filler Polyurethane

  • Makes strong repair pastes
  • Combine with PU for fast gap filling
  • Curing and workability according to product sheet

Cut Fiberglass 12 mm

  • Increases impact resistance and tensile strength
  • Good for corners/edges and support caps
  • Distribute evenly to avoid lumps

Metal powders - aluminum, copper, brass & bronze

Create cold-casting and metallic effects in epoxy or PU. Post-treatment (sanding, polishing, or patination) gives a realistic metal look.

  • Aluminum powder: light silver-gray, technical/industrial effect
  • Copper powder: warm reddish brown, suitable for patina
  • Brass powder: gold tint, classic decorative
  • Bronze powder: deep brown-gold, sculpting effect

Tip: First mix a small amount of slurry with one part resin and then add it to the main mixture for a lump-free distribution. Always follow the system's maximum fill level.

Pretreatment & finishing

Isopropanol Alcohol 99.7%

  • Clean and degrease before gluing/coating
  • Evaporates quickly; use lint-free cloths
  • Caution: Flammable – ventilate well, avoid sparks

Double Coat Mat Set

  • Durable, matte topcoat over epoxy/PU/wood
  • Abrasion and chemical resistant (consult TDS)
  • Processing according to mixing ratio and pot life

Araldite 2012 - Epoxy glue (50 ml)

  • Fast curing, strong and impact resistant
  • For metal, ceramics and many plastics*
  • Dosing package (A/B) – clean, repeatable connections

Frequently Asked Questions (FAQ)

Which filler do I choose for vertical applications?

Fumed silica makes systems thixotropic (non-sag). For structural fill, it can be combined with chopped fiberglass.

I want to lose weight; what do I use?

Fillite 355 (microballoons) reduces weight and sands well—ideal for filler and volume build-up.

How do I get a real metallic effect?

Use a high percentage of metal powder (within the TDS limits), pour, let harden, and polish the surface. Patinas add extra depth.

Can I use IPA 99.7% for everything?

For cleaning/degreasing on compatible surfaces only. Test for colorfastness and observe fire safety.
