(ISO 34) Movement Capability ±25% (ISO 9047) ±35% (ASTM C 719) Service Temperature −40 °C to +150 °C Joint Design The joint width must be designed to suit the joint movement required and the movement capability of the sealant. The joint width shall be ≥ 10 mm and ≤ 40 mm. The joint depth shall be ≤ 20 mm. A width to depth ratio of 2:1 must be maintained (for exceptions, see table below). Backing Material Use polyethylene foam backing rods. Sag Flow 2 mm approx. (20 mm profile, 50 °C) (ISO 7390) Ambient Air Temperature +5 °C to +40 °C, min. 3 °C above dew point temperature Substrate Temperature +5 °C to +40 °C Curing Rate 2 mm/24 hours approx. (23 °C / 50% r.h.) (CQP 049-2) Skin Time 25 minutes approx. (23 °C / 50% r.h.) (CQP 019-1) Tooling Time 20 minutes approx. (23 °C / 50% r.h.) (CQP 019-2) APPLICATION INSTRUCTIONS SUBSTRATE PREPARATION The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Sikasil®-670 Fire adheres without primers and/or activators APPLICATION METHOD / TOOLS Sikasil®-670 Fire is supplied ready to use. After the necessary substrate preparation, insert a suitable backing rod to the required depth and apply any primer if necessary. Insert a foil pack or cartridge into the sealant gun and extrude Sikasil®-670 Fire into the joint making sure that it comes into full contact with the sides of the joint and avoids any air entrapment. Sikasil®-670 Fire sealant must be firmly tooled against the joint sides to ensure adequate adhesion. It is recommended to use masking tape where exact joint lines or neat lines are required. Remove the tape within the skin time. Do not use tooling products containing solvents. CLEANING OF TOOLS Clean all tools and application equipment immediately after use with Sika® Remover-208 and/or Sika® TopClean T. Once cured, residual material can only be removed mechanically. FURTHER DOCUMENTS ▪ Safety Data Sheet (SDS) ▪ EN 13501-2 classification report ▪ ETAG 026 assessment report ▪ Brochure Sika Fire Protection Solutions LIMITATIONS ▪ Sikasil®-670 Fire cannot be overpainted. Colour variations may occur due to exposure to chemicals, high temperatures and/or UV-radiation (especially with the colour shade white). However, a change in colour is purely of aesthetic nature and does not adversely influence the technical performance or durability of the product. ▪ Do not use Sikasil®-670 Fire on natural stone. Do not use Sikasil®-670 Fire on bituminous substrates, natural rubber, EPDM rubber or on any building materials which might bleed oils, plasticizers or solvents that could attack the sealant. ▪ Do not use Sikasil®-670 Fire to seal joints in and around swimming pools. ▪ Do not use Sikasil®-670 Fire for joints under water pressure or for permanent water immersion. ▪ Do not expose uncured Sikasil®-670 Fire to alcohol-containing products as this may interfere with the curing reaction.

Sika Firerate is a gunnable acrylic based jointing and sealing compound specially formulated with inorganic fillers to provide a fire barrier. Sika Firerate has been tested for fire resistance for up to 4 hours according to AS 1530.4 in masonry wall and floor joints. USE Sika Firerate is suitable for sealing joints in concrete or masonry that must have a fire rated resistance to Australian Standards. Sika Firerate also fulfils the basic function of a gap filler and joint sealant against water and dust penetration. CHARACTERISTICS AND ADVANTAGES Safe to use – contains no asbestos or fibres. Paintable. Good flexibility and adhesion to concrete and masonry. Interior use only. Easily applied with normal caulking equipment. Easy tooling off. Economical – single product for both fireproofing and sealing functions. Water clean-up of tools and equipment while still uncured. Excellent acoustic performance, test report available. COLOUR Grey CHARACTERISTICS/ADVANTAGES • Up to 4 hours fire resistance according to AS 1530.4 • Very good resistance to weathering • Movement capability of ± 20 % • Easy to smooth and very good workability • Good adhesion to many different substrates • Water clean-up of uncured sealant . APPROVALS / STANDARDS • AS 1530.4 FRL • ISO 717.2 Rw (Ctr) = 64 (-13) SUBSTRATE PREPARATION The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles.

Features Resists intense heat Sets hard Water clean up Where can this product be used? Repairing bricks in fireplaces and chimneys Sealing flues in pot-belly stoves Filling cracks in ironworks and bricks  What materials is this product suitable for? Brick Metal Concrete How to Use: Remove all dust, grease and loose debris before applying material. Dampen the cavities on porous surfaces for better adhesion. Apply Fireproof Cement firmly into holes and cracks with a damp knife or spatula. Allow Fireproof Cement to dry a minimum of 48 hours before exposure to heat. If Fireproof Cement is stiff slacken with a little water. Limitations: Fireproof Cement is not an adhesive - it is a filling compound. Not recommended for external use e.g. BBQ's, incinerators etc. Fireproof Cement is not suitable for use in kilns. Fireproof Cement is not recommended for moving joints such as expansion joints as it sets rigidly Hardened material cannot be resoftened with water.
