Specially formulated machinable boards
with associated adhesives and putty

Composite resins are specially designed
for the production of high-performancecomposites also giving good wettingof difficult fibre materials, variable
viscosity for different production
processes and application temperature
ranges up to 225 °C.

Extrudable pastes and mass-casting
systems are tailor-made products
for making joint-free, near net shapes
in styling design, cubing models anddiverse moulds in high-quality.

Excellent processing and good resistance
to external influences are the deciding
features of gelcoats.

These materials provide since decades
beneficial alternative solutions technically
and/or economically versus traditional
methods using wood or metal.

Our laminating and multipurpose
resins can be used in different stagesof manufacture in the construction ofmodels, negatives, moulds and tools
and result in high-grade laminates withexcellent strength.

• Vacuum Casting Systems• Low Pressure RIM-Systems
For rapid production our vacuum casting
systems based on polyurethane are
the perfect solution. They simulate themajority of characteristics of thermoplastic series materials without limits inshapes intricacy.
The same applies for low pressure
RIM-systems, which are processed withthe help of 2-component-mixing andmetering machines. Our RIM products
can be used for small and large volume
parts and are suitable for high-classprototypes as well as short runs andserial production.

The large range of tooling resins can beused in many different ways. They aresuitable for the quick and inexpensive
manufacture of production equipment
such as foam-, RIM- and vacuumforming
moulds or foundry patterns and metal
sheet forming tools.
There are also suitable casting resins formaking auxiliary items such as masterand core models or negatives.
Some fastcast resins are particularly
dedicated to make scale models
production, mock ups and prototypes.
The system selected depends on thecasting procedure in question, e.g. mass
casting, backfill or facecasting.

DESIGN AND STYLING BOARDSDESIGN AND STYLING BOARDSLight PUR foam boards are most favored materials thatdesigners prefer to work with to create shaped forms or
styling prototypes/models.
These specially formulated boards are offered from 0.08 to
0.35 g/cm3 density with optimum balanced mechanical andthermal properties.
All boards feature excellent machinability by hand or CNC
milling, producing mainly shavings and minimal dust while
delivering a fine and non-powdery surface.

range. The combination of superior surface
quality and the use of dedicated adhesive
Labelite Glue enables an easy painting withlowest appearance of glue lines.

Sika Advanced Resins offers a wide range of tooling boards
specially dedicated to make foundry patterns and cold coreboxes.
Model-makers can select the most suitable board for theirrequirement in durability: abrasion resistance level from low
to higher series of sand mouldings to be made as well as
strength and dimensional stability.
These boards are cost-effective alternative solutions tometallic patterns and cold core boxes for most foundry
processes up to medium size series.

MODEL AND MOULD MAKINGPASTESMODEL & MOULD MAKING PASTES
Large size models and tools are made with extrudable PUR
and epoxy pastes providing a workable surface applied ontoa stable core substructure. This technique is widely used tomake plugs for boats or wind blades as well as automotive or
architectural designs. This technology is beneficial versus
boards as offering lighter models with a smooth and seamlesssurface (joint-free unlike boards).
The PUR base allows for standard performance the fast-making
of models without any post-curing.
The epoxy range provides higher dimensional stability andheat resistance for models or direct tooling applications incomposite parts making.

FASTCAST RESINSPUR CASTING RESINSFILLED FASTCAST RESINSUNFILLED FASTCAST RESINSFilled fastcast resins are especially suitable for making
e.g. master, core models, negatives and patterns with large
dimensions and are characterized by low shrinkage.

The unfilled fastcast resins are usually used for making detailed
models and mouldings with thin walls due to their excellent
flowability. They can, however, be cast in thicker layers byadding filling materials to them.

PUR Casting systems with long pot life
SikaBiresin® F46• Prefilled casting resin can be cast in thick sections(e.g. backfilling)• Results in durable core models with high dimensional accuracy
SikaBiresin® F48 and SikaBiresin® F50• Offer lower viscosity and are used unfilled by face castingprocess• Both systems can be filled with high filler loading to usethem as high-grade mass casting systems with highstrength values

ADHESIVE AND PUTTY FILLERSYSTEMS FOR BOARDS AND PASTESADHESIVE AND PUTTY FILLER SYSTEMSFOR BOARDS AND PASTESADHESIVES

The adhesive and putty filler systems are specially adapted
to Sika Advanced Resins boards. This relates to colour andmechanical-physical properties. This results in a similiar
behaviour regarding machinability and subsequent use inapplication.

In the development of adhesives, special attention is paid toachieving a sufficiently high degree of adhesive strength andrapid curing.
