Crestamould RTR 4010PA is a new, improved rapid tooling resin which incorporates better handling properties, lower viscosity,improved shrinkage control and is catalysed with standard MEKP catalyst. Crestamould RTR 4010PA is a thixotropic, filled, low profile resin for hand-lay mould making applications.
Crestamould RTR 4010PA helps to achieve faster mould making and eliminates surface distortion, forming part of our new mould making system, which also comprises Crestamould Gelcoat 15PA.
Applications
Crestamould® RTR 4010PA is designed for hand-lay applications and must be allowed to attain a
minimum workshop temperature of 18°C before use (20°C - 24°C is recommended). It should be mixed
thoroughly prior to use and requires only the addition of MEKP catalyst to start the curing reaction. The
recommended catalyst is Catalyst M (or Butanox® M50), which should be added at 1% into the resin and
thoroughly dispersed. The recommended resin-to-glass ratio for chopped strand mat glass reinforcement
is at least 3-to-1 by weight.
Although Crestamould® RTR 4010PA is designed for hand lay application, it can also be spray applied.
Please contact the Scott Bader Technical Service department if further information is needed.
The design, complexity and size of the mould will determine optimum reinforcement levels and thickness.
At least 3 layers of 450gsm chopped strand glass mat, or equivalent, is required and should be applied in
a single operation consolidating between layers, to achieve sufficient cure and low shrink performance.
The material will undergo a colour change becoming whiter as the curing reaction takes place.
