Type 1XR High Density Fireproofing

Southwest Fireproofing Type 1XR is a high density Cementitious Fireproofing tested for petrochemical fires and exterior service conditions.

Descriptions

Southwest Fireproofing Type 1XR^TM is a high density mixture of Portland cement and vermiculite. This combination has formed the basis of spray-applied fireproofing materials for over 50 years. Formulation developments over the years have improved application and service characteristics while maintaining the excellent fire resistance and durability of this proven mixture.

Specific Uses

Type 1XR^TM is a durable high density fireproofing specifically designed for petrochemical service conditions. This product formula can also be used for chemical processing structures as well as other exterior or interior conditions requiring durable fireproofing.

Benefits

Type 1XR^TM has excellent workability, spraying and adhesion characteristics. Type 1XR^TM sets to form a hard and durable monolithic barrier with superior performance characteristics.

Type 1XR^TM is comprised of common Portland cement, vermiculite and other ingredients requiring only the addition of water to produce a wet mix easily applied with standard industry equipment.

Applications

Type 1XR^TM is used in petrochemical and other demanding situations requiring a high density product as shown in the Selection Chart.

Typical uses for Type 1XR^TM are:

	Petrochemical
	Chemical processing
	Clean room production
	Heavy manufacturing
	Material handling and storage
	Maintenance and testing
	Transportation terminals
	Gymnasiums and arenas

TYPE 1XR CEMENTITIOUS FIREPROOFING IS SPRAY-APPLIED TO STRUCTURAL COMPONENTS OF BUILDINGS FOR FIRE RESISTANCE. UNDERWRITERS LABORATORIES FIRE TEST RESULTS HAVE QUALIFIED IT FOR USE IN OVER 100 DESIGNS. UL DESIGN PAGE

TYPE 1XR CEMENTITIOUS FIREPROOFING IS DERIVED FROM THE BENEFICIAL COMBINATION OF PORTLAND CEMENT AND VERMICULITE. IT IS NON-COMBUSTIBLE AND UNDER FIRE, IT RELEASES WATER OF CRYSTALLIZATION WHICH TURNS TO STEAM AND RETARDS HEAT TRANSFER.
