Laminating epoxy resin

add remove What is STRATPOXY resin? insert_link

STRATPOXY is a two-component epoxy resin (resin + hardener) designed for lamination, repair, waterproofing, and the manufacture of composite parts for individual users.

add remove What is the difference between STRATPOXY and STRATPOXY PLUS? insert_link

  • STRATPOXY (standard): DIY, model making, waterproofing, simple repairs. Maximum temperature 50°C.

    STRATPOXY PLUS: more technical repairs (carbon, sandwich structures, vacuum processes). Maximum temperature up to 90°C.

add remove Is STRATPOXY suitable for beginners? insert_link

Yes, standard STRATPOXY is perfectly suitable for beginners. STRATPOXY PLUS requires more precision but remains accessible to a careful individual.

add remove Which materials does STRATPOXY resin adhere to? insert_link

Wood, sanded metal, fiberglass, carbon fiber, sanded PVC and ABS. It does not adhere properly to silicone, Teflon, or greasy plastics.

add remove What is the correct resin mixing ratio? insert_link

  • STRATPOXY: 100 g of resin / 38 g of hardener (or 2 parts resin / 1 part hardener by volume)

  • STRATPOXY PLUS: 100 g of resin / 37 g of hardener (weight ratio only)

add remove How long can you work with the resin? insert_link

At approximately 20°C:

  • STRATPOXY Slow: 1h45

  • STRATPOXY Fast: 35 min

  • STRATPOXY PLUS Slow: 4h

  • STRATPOXY PLUS Fast: 35 min
add remove How to calculate the required amount of resin? insert_link

Simple rule: resin weight ≈ fabric weight. Add approximately 10% extra.

add remove Is surface preparation required before application? insert_link

Yes. You must always: degrease, sand (80-grit), and carefully remove all dust.

add remove In what order should the resin and fabric be applied? insert_link

To achieve proper lamination with a fabric (glass, carbon, flax, aramid), it is important to follow the correct application sequence in order to ensure good fibre impregnation and avoid the formation of air bubbles.

The first step is to apply a thin layer of resin directly onto the substrate (wood, foam, metal, composite, etc.). This layer prepares the surface and improves the adhesion of the fabric.

Next, place the dry fabric onto this first layer of resin. The resin already present on the substrate helps hold the fabric in place and facilitates its impregnation.

Once the fabric is properly positioned, apply another layer of resin on top using a brush, roller, or spatula. The goal is to fully impregnate the fibres until the fabric becomes translucent (in the case of glass or flax) or uniformly saturated.

After applying the resin, it is recommended to perform air removal using a laminating roller (bubble roller). This step helps remove trapped air within the fibres and ensures a uniform and strong laminate.

If multiple layers of fabric are required, simply repeat the same process:
resin → fabric → resin → air removal.

Following this sequence ensures optimal fibre impregnation, good bonding between layers, and maximum mechanical performance of the final composite.

add remove When can a STRATPOXY-made part be demolded? insert_link

  • STRATPOXY: 20 to 34 hours

  • STRATPOXY PLUS: 16 to 48 hours

    Final strength is reached after several days.
