Crestamould

Crestamould® B12R Sealer is a MEKP catalysed, brushable, slightly thixotropic sealer designed to coat expanded and extruded polystyrene foams. It acts as a chemical bridge and barrier between the polystyrene foam and either a laminate or a machinable polyester-based tooling paste such as Crestamould T27/T28. Its main use is for sealing of polystyrene foam blanks used in 5-axis plug and pattern work.

Crestamould® T28 is an extrudable modified polyester compound designed for milling of small and large plugs or direct limited production molds with Computer Numerical Control (CNC) multiple axis machines. It can be extruded with conventional FRP putty dispensing equipment. The product provides a homogeneous substrate that prevents print from the underlying structure and gives sufficient flexibility to prevent cracks.

Crestamould® Gelcoat 15PA (B) is a pre-accelerated brush gelcoat specially formulated from a vinyl ester base resin and has been developed to have excellent gloss retention alongside impact, heat and chemical resistance. The viscosity profile ensures even coverage with minimal drainage and low film porosity. Crestamould® Gelcoat 15PA (B) is recommended for use in the manufacture of high quality FRP composite tooling.

Crestamould® Resin 474PA is a thixotropic, pre-accelerated orthopthalic polyester resin with good heat and chemical resistance properties. This product is suitable for the construction of tanks, pipes, and fume stacks to operate in environments where heat and chemical resistance are both required. A non-thixotropic, non-accelerated version of this resin is available as Crystic® 198.

Crestamould® VE 679PA is a pre-accelerated, thixotropic, DCPD-modified vinyl ester resin. This product has been developed for use as a skin coat in marine and tooling applications. It has excellent blister resistance, reduced print through, a 23-minute gel time, and Lloyd's approval.

Crestamould® VE 690PA is a pre-accelerated, thixotropic, modified vinyl ester resin. This product is developed for use as a skin coat in tooling and marine applications. It has excellent blister resistance, and it significantly reduces the occurrence of print-through to produce durable moldings with an enhanced surface finish.

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. It is a thixotropic, filled, low profile resin which helps to achieve faster mold making and eliminates surface distortion. This product was formulated for hand-lay mold making applications.

Crestamould® T27 Polyester Compound is designed for milling of large plugs (10-25 m, 30-75 ft, ) or direct limited production moulds with Computer Numerical Control (CNC) multiple axis machines. It provides a homogeneous substrate that prevents print from the underlying structure, and gives sufficient flexibility to prevent cracks.

Crestamould® Gelcoat 15PA (S) is a pre-accelerated spray gelcoat specially formulated from a vinyl ester base resin and has been developed to have excellent gloss retention alongside impact, heat and chemical resistance. The viscosity profile ensures even coverage with minimal drainage and low film porosity. Crestamould® Gelcoat 15PA (S) is recommended for use in the manufacture of high quality FRP composite tooling.

Crestamould® T29 Extrudable is a modified polyester compound designed for the milling of large plugs or production molds with CNC multiple axis machines. This material combines unique qualities and it can be extruded up to a thickness of approx. 15mm (0.6”). It provides a homogenous substrate that prevents print from the underlying structure.

Crestamould® T29 Sprayable is a modified polyester compound designed for the milling of large plugs or production molds with CNC multiple axis machines. This material combines unique qualities and can be sprayed with few passes up to a thickness of approx. 1-3mm (0.04 - 0.12”). It provides a homogenous substrate that prevents print from the underlying structure.

Crestamould® B21 Sealer is a brushable sealing laminating resin for polystyrene foam surfaces. When used with a chopped-strand mat, this sealer provides a styrene-resistant barrier between the polystyrene plug and styrenated tooling pastes. It has good adhesion to tooling pastes like Crestamould® T29. Crestamould® B21 sealer has a low styrene content, significantly reducing polystyrene surface erosion compared to traditional styrene-containing resins. The sealer can be used to laminate CSM to create a more structurally stable foundation for mold production.
