1 Technical Data Hygiene and Waterproofing Solutions FLAMELOCK Description : Water based fire retardant coating Type : Acrylic\Boron polymer blend Use : To retard and reduce flame spread. The product is fully compliant to International fire safety ratings. Advantages : Excellent adhesion to most substrates Highly elastic, durable coating Excellent exterior and interior durability UV resistant Waterproof when cured Resistant against a wide range of chemical agents It can be used as a barrier coating Flamelock is water based coating which forms a tough, flexible, chemical resistant membrane with outstanding fire retardant properties. Suitable for both internal and external applications, it achieves the highest fire safety rating to international standards including BS 476 parts 3, 6 and 7. Upon curing, it is completely waterproof and forms an effective defence against aggressive elements such as chlorides, acid gases and atmospheric pollution. It presents an effective vapour barrier and is suitable for use over a wide range of common substrates. Available in a range of decorative colours, Flamelock is UV stable, so it remains highly elastomeric throughout its design life. Flamelock complies with all the international asbestos control legislation. Typical test data (General) Service temperature : - 50 o C to o C. No change after cyclic Testing Minimum Application temperature : 3 o C, providing this is above dew point Drying times : Approximately 2 hours in ideal conditions. At lower temperatures or conditions of high relative humidity drying will be retarded. If in doubt, allow 24 hours between coats. Permissible substrate moisture : 20% wood moisture equivalent, as measured by protimeter

(see following section for applications over asbestos) Tensile load : 1,0 kg/cm for 1cm wide strip (@ 350 mic DFT) Elongation : 213% unreinforced Water vapour permeability : BS 3177 (temperate) at 350 mic 16,8g/m 2 /day BS 3177 (temperate) at 510 mic TB 92/F 11,9g/m 2 /day Accelerated weathering : BS hours carbon arc TB 7/F No change Impact resistance : BS 3900 Part E3 TB 24/F Withstands 5 mm indentation on PIR foam without defect Chemical resistance : Resistant to a wide range of reagents, even under total immersion conditions TB 6/F Salt spray to BS 3900 part F4, 2500 hours TB 132/F no corrosion of substrate Approximate solids content : 63,2 % by weight 50,4 % by volume Specific gravity: 1,32 Colour range : white, special colours on request Pack sizes : 5, 10 and 20 litres Cleaning : Water. Dry paint may be removed with polar solvent like xylene and toluene. Miscellaneous technical data (Fire tests) BS 476 part 3 : FAA or SAA designation on polyurethane foam, polyisocyanurate foam and bitumen BS 476 part 5 : P classification (not easily ignitable) on expanded polystyrene and gloss paint

3 BS 476 part 6 : Low index and sub-index ratings (zero in some cases) on expanded polystyrene, gloss paint and plasterboard BS 476 part 7 : Class 1 rated on polyurethane and polyisocyanurate foams, mineral wool, expanded polystyrene, gloss paint, plasterboard, paperboard and asbestos cement. In conjunction with part 6, a class 0 rating. DIN 4102 : B rated on polyurethane foam. TB139/F, 217/F ASTM E-84 : Low rating in the tunnel test. TB 305/D/F Anti-static : Classed as anti-static coating in accordance with BS TB69/F Application details Absorbent surfaces : Apply direct over clean, dry surfaces (fibreboard, cardboard etc) Asbestos cement : Flamelock can be used on asbestos cement, either internally or externally, to prevent further breakdown of the cement binder and to prevent fibre release. Flamelock is also effective in treating the surface of weathered asbestos cement to give expanded life and waterproofing. Always ensure strict compliance to Health and Safety requirements when working with asbestos-containing materials. Treatment : When surfaces are clean, dust free, dry and sound, apply Hydrolock primer. Flamelock can be applied direct to dry internal surfaces but always use Hydrolock primer followed by two coats of Flamelock in areas which are prone to impact. Application : Allow the primer to cure (overnight). Treat partially reinforce areas first before applying two coats of Flamelock. Bitumen : Stable bitumen based paints and bitumen coated metals may be treated. Apply Flamelock over Hydrolock primer. For surfaces liable to bleeding, consult our Technical department. Bitumens containing excess volatiles may damage or discolour the coating. Cement and Plaster substrates : Apply Flamelock over Hydrolock primer to plaster finishes and sound, semi-compressed cement bound

4 boards. Concrete screeds : Apply over Hydrolock primer when treating aged but sound concrete (pre-cast or poured) and stable screeds. Newly applied cementitions materials should be allowed to cure for at least 10 days and ideally 28 days before treatment. Insulation : Apply direct to expanded polystyrene and wrap- (other than asbestos) around pipe insulation. Polyurethane and polyisocyanurate foams either sprayed in situ or slabstock plus lightly dusting materials such as phenolic insulation require pre-treatment with Hydrolock primer. Lining boards : Boards with absorbent surfaces such as limpet, (including asbestos containing plasterboard, Duripanel, Asbestolux etc., require prelining insulation boards) treatment with Hydrolock primer. Consult our technical department for advice about priming precoated boards. Mastics : Use Hydrolock primer over cured polysulphide,but polysulphide may not be applied over an existing Flamelock membrane. Low or high modulus silicones may be applied over Flamelock but Flamelock will not adhere to silicone based mastics. Use Hydrolock primer when treating cured polyurethane. Metals : Always remove rust from ferrous metals and oxidation products from non-ferrous metals. All surfaces should be clean and free from grease and should be prepared in such a way as to reveal bright metal. Hydrometal primer should then be applied as soon as possible in order to prevent flash rusting. Use two coats of primer on badly corroded metals and shot- or grit-blasted surfaces. Galvanised metals may require degreasing or the use of a proprietary pre-treatment wash such as Galv-etch or a galvanised iron degreaser. Painted Surfaces : Apply direct to sanded gloss, oil, alkyd and epoxy paints. Unsanded paints should be cleaned and treated with Hydrolock primer. Sound, clean emulsion, lime wash, polyurethane, bitumen and pitch paints also require pre-treatment with Hydrolock primer. Note, however, that such treatments may not satisfy fire requirements as old

5 paint may be an unsuitable base in the event of a fire. Ensure that existing paints are fully adhered before priming/coating. Test if necessary and remove if not well adhered. Plastics and rubber : Many plastics can be coated directly but plasticized types such as PVC require a ketone solvent wash first. Polyester/EVA/Melamine require pre-treatment with Hydrolock primer. Rubber compounds are a special case; consult our technical department for advice. Existing Flamelock membranes : Clean down thoroughly and apply Hydrolock primer. Coverage Rates Coverage (unreinforced) : 1 st coat 3 4 m 2 /litre 2 nd coat 3 4 m 2 /litre For bridging cracks, joints and expansion joints, reinforce the Flamelock with the appropriate grade chopped strand matt. For overall reinforcement, use either standard or premium grade chopped strand matt. Equipment Rollers : Use only for the embedment of reinforcement Brushes : A wide, soft nylon or bristle brush gives best results. Do not use brushes directly on friable, asbestoscontaining insulation. Airless spray : Most types industrial spray equipment is suitable. Use a tip size between 0,48 and 0,74 mm (19 and 29 thou). Clean-up : Clean brushes and spray equipment with water. Dried Flamelock can be removed with cellulose thinners, xylene or toluene.
