EXO-SET High Density Spray foam system

Click here to download/view PDF version

Product Description

EXO-SET is a zero ODP two component foam system fully formulated to produce a high density rigid spray foam. The system should be processed at a 1:1 volume ratio through suitable spray machinery ( Gusmer, Glas-Craft/Probler etc ) and will produce a closed celled rigid foam of approximately 220kg/m³ density. When fully cured the foam is extremely strong and durable, and is fire retardant in accordance with BS4735.

Uses

EXO-SET is used for speciality scenic replication and reinforcement purposes.

EXO-SET should be applied under standard conditions of temperature and humidity where possible – approximately 20ºC and 50% humidity. The reactivity of the system has been tailored to suit these conditions.

Equipment

EXO-SET can be processed through all standard foam spray machines. The machine should be capable of maintaining the mix ratio at ±2% accuracy and controlling the component temperatures at 40-60°C (variable).

Recommended machine settings

Spray Techniques

The guidelines in Isothane Limited’s standard specification should be followed but the general requirements are as follows.

• The foam reaction gives out a large amount of heat.
• Care must be taken to build up the thickness of foam required gradually, to reduce the risk of scorching.
• The substrate should be clean, dry and free of dirt, grease, oil and loose particles.
• In certain cases primer may be necessary to maximise adhesion.
• Factory conditions should be suitable for spraying with regard to humidity and ambient temperature.

Physical Properties

The reactivity of EXO-SET when tested at the laboratory at 20°C is as follows:

Mix Ratio (by weight) Resin 100 : 114 Iso (EXO –SET [R] : EXO –SET [H])
Mix Ratio (by volume) Resin 100 : 100 Iso (EXO –SET [R] : EXO –SET [H])

Fire Safety

Rigid polyurethane foams are organic, combustible materials and may present a fire risk in certain applications if exposed to fire and/or heat. Do not use welding and cutting torches, flame or any other ignition source on or near such exposed foams. The cured foam is fire retardant to BS4735.

Storage, Handling and Personal Protection

Please consult our separate Material Safety Data Sheet. The MSDS gives a comprehensive list of all aspects of safe handling.
