Description
DELTAShield CRX 700 is a specially formulated high performance, rigid polymer designed for in mold spray applications, mold making applications and the replacement of fiberglass reinforcing.
DELTAShield CRX 700 exhibits excellent structural strength, good thermal stability and very low moisture permeability making it suitable for use in immersion applications.
DELTAShield CRX 700 is spray applied and is tack free in seconds providing very rapid turn around and handling times.
Features
- Extremely fast application
- Extremely fast cure resulting in reduced handling and re-use times
- Good abrasion resistance
- Excellent adhesion
- Very good impact resistance
- Excellent chemical resistance
- Very low moisture absorption
- Stable over a wide temperature range
Typical Uses
- Fabrication of parts traditionally made from Fibreglass
- In mould spraying of components
- Structural support of flexible wear linings
- Structural support of vacuum formed components
