Fortafix High Temperature Adhesive

Fortafix High Temperature Adhesive - Fiborclad

Fortafix High Temperature Adhesive - Fiborclad

An inorganic adhesive cement specifically prepared for its excellent tack, thixotropic, heat and fire resisting properties. FIBORCLAD has a maximum working temperature limit of 850°C. Complies with BS 476: Part 4: Non combustibility test for materials. Fiborclad can be safely used as a fixing or jointing medium where resistance to the spread of flame or fire is a requirement

Typically Used For
FIBORCLAD is a suitable bonding and jointing medium for all types of inorganic wall boards including fibreboard, chipboard, plywood and those based on ceramic and mineral fibres, as well as fibre & mineral wool thermal and acoustic insulation materials. Effective bonds are obtained between these materials and to iron, steel and other metals.

Additional Information
Fiborclad Grade 3 - Low Viscosity @ 6,000/2,800 cP Fiborclad Grade 4 - Medium Viscosity @ 30,000/10,000 cP Fiborclad Grade 7 - High Viscosity @ 200,000/50,000 cP FIBORCLAD possesses good wetting and penetrating powers; sets quickly at high or low temperature and has good application qualities. As a cold setting adhesive it is extremely effective and will form tenacious bonds of extreme durability, which improve with age.

Application
Coverage Rate 4 - 6 m2/litre: FIBORCLAD is economical in use and can be applied by brush, spreader or spray gun. If viscosity adjustment is required "FORTAFIX" THINNERS L.7 may be used without loss of adhesive strength. In very warm atmospheres setting can be retarded by the addition of 5% to 10% clean water according to conditions prevailing at the time of application but it must be noted that the adhesive hardens by loss of moisture and too much added water may prolong hardening if the temperature reduces. IT IS ESSENTIAL THAT ALL SURFACES TO BE BONDED ARE FREE FROM OIL, DUST OR ANY FORM OF SURFACE COATING OR CONTAMINATION. Stir contents of the container prior to use, to overcome the effects of any settlement of the ingredients during storage. Ensure that all surfaces to be bonded sealed or insulated, are degreased, clean and free from contamination. A light surface abrasion of the material to be bonded will increase the amount of surface area available for adhesion and will give improved mechanical key. Apply the adhesive to all surfaces to be bonded. Join and apply moderate pressure to ensure even anchorage and solid contact of the surfaces to be bonded, ensure that all surface are fully wetted by the adhesive. Secure the components and allow the adhesive to set and harden.

Curing
This product is water based. In order to cure of the material it is necessary to fully dry & dehydrate the adhesive, by heating as gently & progressively as time and circumstances will allow. The ease by which full curing can be achieved is dependant on the porosity of the substrate, as well as the amount of available surface through which the adhesive film can dry. The cement should be allowed to harden at a minimum air temperature of 20°C until initial set has taken place. After this period the hardening process may be accelerated using the following typical schedule; Heat from 20° to 80°C @ 4°C per minute (15 minutes). Hold for 10-20 minutes Heat from 80° to 140°C @ 2°C per minute (30 minutes). Hold for 120-180 minutes Heat from 140° to 200°C @ 0.2°C per minute (300 minutes). Above 200°C - raise temperature @ 1°C per minute to required temperature, allow to cool progressively. Hardening and curing times given are approximate in view of possible variations in adhesive volume, glue line thickness, and substrate conditions, all of which will influence curing times.
