Thixotropic agent for gelcoats and top layers on vertical surfaces
A1 Thixotropic A (Thix A) is a liquid additive that thickens A1 acrylic resin (Acrylic One) into a gel. Use it to make a gelcoat or top layer that stays in place, even in moulds with vertical or overhanging parts. Add Thix A to the A1 mix until you reach the thickness you want, up to a maximum of 2 % of the total weight. Adding more reduces the effect.
Key benefits
- Stays put: thickened A1 does not sag on vertical surfaces.
- Clean top layer: suitable for the visible first layer in the mould.
- Low dosage: maximum 2 % of the total weight.
- Combinable: can be used with pigments, dry sand or metal powders.
Typical applications
- ✓ Gelcoats and top layers in moulds
- ✓ Vertical and overhanging parts
- ✓ Coloured or filled show layers with pigment or metal powder
Application
- Mix A1 liquid and A1 powder until smooth.
- Add pigment and/or materials such as dry sand or metal powder if required.
- Add Thix A until the desired thickness is reached, up to a maximum of 2 % of the total weight.
- Brush the top layer into the mould with a layer thickness of at least 1 mm.
- Once the top layer has gelled, normally after 20 to 30 minutes, apply the next layer of A1 within 1 hour, with glass fibre reinforcement if needed. This gives the best adhesion between layers.
Points to note
- ✓ More than 2 % Thix A reduces the thickening effect.
- ✓ Work above 10 °C, ideally at 20 °C.
- ✓ Stored in closed packaging, cool, frost-free and out of direct sunlight, the shelf life is at least 1 year.
